مُرَاجَعَة ٣: أُقَدِّمُ حُجَّةChapter 15: Unit III Assessment

Presenting a supported argument with evidence · Speak and Write Arabic: Independent Communication and Advanced Expression

Chapter Overview

This chapter is the Unit III assessment. It introduces no new grammar, morphology, vocabulary domain, or clause type. Instead, it asks you to bring together everything Unit III has built: stating and qualifying an opinion (Chapter 11), comparing and interpreting evidence (Chapter 12), reading and producing data commentary (Chapter 13), and describing a formal procedure impersonally with the passive voice (Chapter 14). The task that unifies these four chapters is the supported argument — a piece of connected MSA in which you take a position, back it with comparison and data, and, where relevant, explain a process that bears on your case. You will review the key structures from each chapter, read and listen to model arguments, and then plan, draft, and revise your own supported argument in writing and in speech. No system beyond what Chapters 11 through 14 authorized will be required at any point in this chapter.

Learning Objectives

By the end of this chapter, you will be able to:

  1. State a clear thesis and support it with reasons, using the opinion and qualification structures from Chapter 11.
  2. Compare two or more options using elatives and contrast structures from Chapter 12 to strengthen an argument.
  3. Cite and interpret a statistic or data point using the data-commentary language from Chapter 13.
  4. Describe, where relevant to the topic, a formal procedure impersonally using the passive voice and sequence connectors from Chapter 14.
  5. Organize a multi-paragraph argument with a thesis, supporting points, evidence, and a conclusion.
  6. Read and listen to model arguments and identify their thesis, supporting evidence, and organization.
  7. Present a supported argument in writing and in speech, synthesizing all four chapters of Unit III without relying on any unscoped system.

Opening Communication Scenario

Your university's student newspaper is publishing a special issue on improving campus life, and you have been invited to submit a short opinion piece. You have chosen the topic of streamlining the housing-application procedure discussed in Chapter 14. Your piece must take a clear position, compare the current procedure with a proposed alternative, cite at least one figure or statistic to support your case, and — since the topic is a formal procedure — describe part of that procedure impersonally rather than naming specific staff members.

  1. You will review the opinion, comparison, data-commentary, and process-description language from Unit III.
  2. You will read and listen to model supported arguments and identify how each one is organized.
  3. You will plan, draft, and revise your own supported argument, then present it in writing and in speech.
مُرَاجَعَة المُفْرَدَات — Cumulative Vocabulary Review

Cumulative Vocabulary Review

No new vocabulary is introduced in this chapter. The table below regroups the key productive vocabulary from Chapters 11 through 14 by function, since a supported argument draws on all four categories at once.

التَّرْكِيب — Synthesis Focus

Synthesis Focus: Opinion, Comparison, Data, and Process

This section introduces no new structure. It shows how the four systems already active in Unit III combine inside a single supported argument, and it models the kind of paragraph-level organization your own argument should follow.

Synthesis 1 — Thesis plus qualification (Chapter 11)
أَعْتَقِد أَنَّ ..., وَإِن كَان ذَلِك صَحِيحًا إِلَى حَدٍّ مَا فَقَط
An argument normally opens with a thesis and, where appropriate, a qualification that shows the writer has considered the limits of the claim, exactly as taught in Chapter 11.
أَعْتَقِد أَنَّ عَمَلِيَّة طَلَب السَّكَن الجَامِعِيّ تَحْتَاج إِلَى تَبْسِيط، وَإِن كَانَت بَعْض الخُطُوَات ضَرُورِيَّة فِعْلًا.
I believe that the university housing-application process needs to be simplified, even though some steps are indeed necessary.
Synthesis 2 — Comparison as support (Chapter 12)
النِّظَام المُقْتَرَح أَكْثَر ... مِن النِّظَام الحَالِيّ
A comparison strengthens a thesis by placing the current situation next to a proposed alternative, using the elatives and contrast connectors from Chapter 12.
النِّظَام المُقْتَرَح أَكْثَر وُضُوحًا مِن النِّظَام الحَالِيّ، لِأَنَّه يُحَدِّد مَوَاعِيد كُلّ خُطْوَة بِوُضُوح.
The proposed system is clearer than the current system, because it clearly specifies the deadlines for each step.
Synthesis 3 — Data as evidence (Chapter 13)
تُشِير الإِحْصَاءَات إِلَى أَنَّ ... بِنِسْبَة ...
A statistic gives an opinion concrete support, exactly as practiced in the data-commentary work of Chapter 13.
تُشِير الإِحْصَاءَات إِلَى أَنَّ ثَلَاثِين بِالمِئَة مِن الطُّلَّاب الجُدُد يُوَاجِهُون تَأْخِيرًا فِي الحُصُول عَلَى نَتِيجَة الطَّلَب.
The statistics indicate that thirty percent of new students face delays in receiving the result of their request.
Synthesis 4 — Process description within an argument (Chapter 14)
أَوَّلًا، يُقَدَّم ... ثُمَّ يُرَاجَع ... وَهَذِه الخُطْوَة بِالذَّات هِي الَّتِي تَحْتَاج إِلَى تَعْدِيل
When the topic of an argument concerns a procedure, the passive process-description language from Chapter 14 lets the writer point to a specific step as the source of a problem, without naming individuals.
أَوَّلًا، يُقَدَّم الطَّلَب إِلِكْتْرُونِيًّا، ثُمَّ يُرَاجَع مِن قِبَل المَكْتَب. وَهَذِه الخُطْوَة بِالذَّات هِي الَّتِي تَحْتَاج إِلَى تَعْدِيل، لِأَنَّهَا تَسْتَغْرِق وَقْتًا طَوِيلًا.
First, the request is submitted electronically, then it is reviewed by the office. This particular step is the one that needs to be revised, because it takes a long time.

Recycled structures used in this chapter: every structure above was activated in Chapters 11 through 14 and is reproduced here for synthesis only; no structure is introduced for the first time in this chapter, consistent with the assessment-chapter boundary for Unit III.

Model Dialogue

هِبَة and يُوسُف, staff writers for the student newspaper, discuss هِبَة's draft opinion piece before submission.

يُوسُف
مَا رَأْيُكِ فِي عَمَلِيَّة طَلَب السَّكَن؟ هَل تَحْتَاج إِلَى تَغْيِير حَقِيقِيّ؟What's your opinion of the housing-application process? Does it really need to change?
هِبَة
أَعْتَقِد أَنَّهَا تَحْتَاج إِلَى تَبْسِيط، وَإِن كَانَت خُطُوَاتُهَا الأَسَاسِيَّة مَعْقُولَة إِلَى حَدٍّ مَا.I believe it needs simplification, even though its basic steps are reasonable to some extent.
يُوسُف
هَل عِنْدَكِ دَلِيل عَلَى ذَلِك؟Do you have evidence for that?
هِبَة
نَعَم. تُشِير الإِحْصَاءَات إِلَى أَنَّ ثَلَاثِين بِالمِئَة مِن الطُّلَّاب الجُدُد يُوَاجِهُون تَأْخِيرًا. وَالخُطْوَة الَّتِي تُرَاجَع فِيهَا الطَّلَبَات هِيَ الأَبْطَأ.Yes. The statistics indicate that thirty percent of new students face delays. And the step in which requests are reviewed is the slowest.
يُوسُف
وَبِمَاذَا تُقَارِنِين النِّظَام الحَالِيّ؟And what do you compare the current system to?
هِبَة
أُقَارِنُه بِنِظَام إِلِكْتْرُونِيّ مُوَحَّد يُطَبَّق فِي جَامِعَات أُخْرَى، وَهُوَ أَكْثَر وُضُوحًا وَأَسْرَع مِن نِظَامِنَا الحَالِيّ.I compare it to a unified electronic system used at other universities, which is clearer and faster than our current system.

Guided Practice

تَمْرِين ١ — Identify the function. Label each sentence below as thesis, comparison, data support, or process description.

  1. أَعْتَقِد أَنَّ الجَامِعَة يَجِب أَن تُبَسِّط عَمَلِيَّة التَّسْجِيل.
  2. تُشِير الإِحْصَاءَات إِلَى أَنَّ نِصْف الطُّلَّاب يُعَانُون مِن التَّأْخِير.
  3. النِّظَام الجَدِيد أَكْثَر كَفَاءَة مِن النِّظَام القَدِيم.
  4. أَوَّلًا، يُقَدَّم الطَّلَب، ثُمَّ يُرَاجَع خِلَال أُسْبُوعَيْن.

تَمْرِين ٢ — Build a supporting paragraph. Combine the four sentence types from Exercise 1 into one short, organized paragraph, adding connectors where needed.

تَمْرِين ٣ — Strengthen a weak argument. The sentence below states an opinion with no support. Add one comparison and one statistic to strengthen it.

  1. أَعْتَقِد أَنَّ المَكْتَبَة يَجِب أَن تَبْقَى مَفْتُوحَة لَيْلًا.

Listening Assessment

Ask your instructor, a partner, or a text-to-speech tool to read the following short opinion segment aloud twice at a moderate pace. Listen without reading along the first time, then answer the questions below.

أَعْتَقِد أَنَّ نِظَام تَسْجِيل المَوَادّ الدِّرَاسِيَّة فِي جَامِعَتِنَا يَحْتَاج إِلَى إِعَادَة نَظَر، وَإِن كَانَ قَد تَحَسَّن فِي السَّنَوَات الأَخِيرَة. تُشِير الإِحْصَاءَات إِلَى أَنَّ عِشْرِين بِالمِئَة مِن الطُّلَّاب لَا يَحْصُلُون عَلَى المَوَادّ الَّتِي يَخْتَارُونَهَا فِي المَرَّة الأُولَى. وَعِنْدَمَا نُقَارِن نِظَامَنَا بِالنِّظَام المُسْتَخْدَم فِي جَامِعَات أُخْرَى، نَجِد أَنَّ ذَلِك النِّظَام أَكْثَر مُرُونَة، لِأَنَّه يَسْمَح بِالتَّسْجِيل المُبَكِّر لِلطُّلَّاب المُتَفَوِّقِين. أَوَّلًا، يُقَدَّم طَلَب التَّسْجِيل إِلِكْتْرُونِيًّا، ثُمَّ يُرَاجَع تِلْقَائِيًّا حَسَب الأَوْلَوِيَّة. وَهَذِه الخُطْوَة بِالذَّات، خُطْوَة تَحْدِيد الأَوْلَوِيَّة، هِيَ الَّتِي أَقْتَرِح تَعْدِيلَهَا.

مُهِمَّة الاسْتِمَاع — Listening task

  1. What is the speaker's thesis about the course-registration system?
  2. What statistic does the speaker cite, and what does it support?
  3. What comparison does the speaker make, and what does it show?
  4. Which specific step in the process does the speaker propose to change?

Speaking Assessment

تَدْرِيب مُوَجَّه — Controlled practice: State and support one point

Choose one campus topic (library hours, dining options, course registration, housing) and produce one sentence each for thesis, comparison, and data support, without yet combining them into a full argument.

مُهِمَّة تَوَاصُل — Communicative task: Present your argument to a partner

Present your full supported argument to a partner in under three minutes, using at least one thesis statement, one comparison, one statistic, and, if your topic involves a procedure, a passive process description. Your partner should ask you at least one follow-up question using a structure from Chapters 11 through 14.

لِلْمُتَعَلِّمِينَ المُسْتَقِلِّينَ — Solo alternative

Record yourself presenting your supported argument, then listen back and check that you used at least one structure from each of Chapters 11, 12, 13, and 14.

Reading Assessment

Read the short opinion piece below, then answer the comprehension questions. Predictable short vowels on familiar words remain unmarked, consistent with the reading level established across this unit.

هَل نَحْتَاج إِلَى نِظَام أَبْسَط لِطَلَب المِنَح الدِّرَاسِيَّة؟

مِن وِجْهَة نَظَرِي، تَحْتَاج عَمَلِيَّة طَلَب المِنَح الدِّرَاسِيَّة فِي جَامِعَتِنَا إِلَى تَبْسِيط حَقِيقِيّ، وَإِن كَانَت الجَامِعَة قَد حَسَّنَت بَعْض جَوَانِبِهَا مُؤَخَّرًا. تُشِير الإِحْصَاءَات إِلَى أَنَّ نِصْف الطَّلَبَات تَقْرِيبًا تُرْفَض بِسَبَب نَقْص فِي الأَوْرَاق، لَا بِسَبَب عَدَم اِسْتِيفَاء الشُّرُوط الأَسَاسِيَّة. أَوَّلًا، يُقَدَّم الطَّلَب مَع مَجْمُوعَة كَبِيرَة مِن الأَوْرَاق. ثُمَّ يُرَاجَع المِلَفّ مِن قِبَل لَجْنَة المِنَح. بَعْد ذَلِك، تُعْتَمَد الطَّلَبَات المُسْتَوْفِيَة، وَتُرْفَض البَاقِيَة. وَعِنْدَمَا نُقَارِن هَذَا النِّظَام بِنِظَام إِلِكْتْرُونِيّ مُبَسَّط تَسْتَخْدِمُه جَامِعَات أُخْرَى، نَجِد أَنَّ ذَلِك النِّظَام أَكْثَر وُضُوحًا وَأَقَلّ تَعْقِيدًا. لِذَلِك، أَقْتَرِح أَن تُرَاجِع الجَامِعَة قَائِمَة الأَوْرَاق المَطْلُوبَة، لِأَنَّ هَذِه الخُطْوَة بِالذَّات هِيَ سَبَب مُعْظَم حَالَات الرَّفْض.

أَسْئِلَة الفَهْم — Comprehension questions:

  1. What is the writer's thesis about the scholarship-application process?
  2. What statistic does the writer cite, and what claim does it support?
  3. What comparison does the writer make, and what conclusion does it lead to?
  4. Which specific step does the writer identify as the main problem, and what does the writer propose?

Writing Workshop — A Supported Argument

In this workshop, you will plan, draft, and revise a short, organized opinion piece that combines a thesis, a comparison, a statistic, and — where relevant to your topic — a passive process description, using only structures activated in Chapters 11 through 14.

  1. Step 1 — Choose a topic. Select a campus or community topic that involves a decision, a comparison, and, ideally, a formal procedure.
  2. Step 2 — State your thesis. Open with أَعْتَقِد أَنَّ or مِن وِجْهَة نَظَرِي, adding a qualification if appropriate.
  3. Step 3 — Add a comparison. Compare your proposal with the current situation or an alternative, using an elative structure from Chapter 12.
  4. Step 4 — Cite evidence. Add a statistic or data point using تُشِير الإِحْصَاءَات إِلَى أَنَّ or a similar structure from Chapter 13.
  5. Step 5 — Describe the relevant procedure, if any. If your topic involves a process, describe it impersonally using the passive and sequence connectors from Chapter 14.
  6. Step 6 — Close with a recommendation. End with a sentence that restates your position and, if appropriate, names the specific step or point you propose to change.
  7. Review your draft against the checklist below.

قَائِمَة المُرَاجَعَة — Editing checklist:

  • My paragraph states a clear thesis in the opening sentence.
  • I included at least one comparison using an elative structure.
  • I cited at least one statistic or data point to support my thesis.
  • If my topic involves a procedure, I described it impersonally using the passive voice and sequence connectors.
  • My closing sentence restates my position clearly.
  • I did not introduce any system beyond what Chapters 11 through 14 authorized.

Culture and Communication

Culture in Context — Opinion writing in student and public media

Student newspapers, public forums, and opinion columns across Arabic-speaking universities and media outlets commonly combine a clearly stated position with supporting evidence and, where relevant, a description of the institutional process being discussed. The combination of opinion, comparison, and data commentary you have practiced across Unit III reflects a style that is genuinely common in formal and semi-formal MSA writing on public topics.

Regional Variation — Institutional topics vary, structure does not

The specific institutions, procedures, and figures discussed in a supported argument will differ from country to country and from one university system to another. The underlying structure of a supported argument — thesis, comparison, evidence, and, where relevant, process description — remains stable across these institutional differences.

Common Mistakes to Avoid

Common Mistake — Stating an opinion with no support

Error: writing a thesis sentence and moving directly to a conclusion, without a comparison or a statistic in between.

Correction: follow the thesis with at least one comparison and one piece of data, as modeled in this chapter's Reading Assessment passage.

Common Mistake — Mixing active and passive when describing a procedure

Error: beginning a process description in the passive (يُقَدَّم الطَّلَب) and then switching to the active with a named agent (وَبَعْدَهَا المُوَظَّف يُرَاجِع الطَّلَب) partway through.

Correction: keep the entire procedure in the passive, as taught in Chapter 14, unless the argument specifically requires naming who acts.

Common Mistake — Citing a statistic without connecting it to the thesis

Error: inserting a number or percentage without explaining what it demonstrates, leaving the reader to guess why it matters.

Correction: follow the statistic with a short interpretive sentence, such as يَدُلّ ذَلِك عَلَى أَنَّ, connecting the figure directly back to the thesis.

Chapter Summary

This chapter introduced no new grammar, morphology, or vocabulary. It synthesized the four major systems of Unit III — opinion and qualification (Chapter 11), comparison and interpretation (Chapter 12), data commentary (Chapter 13), and passive process description (Chapter 14) — into a single supported argument. You reviewed the key vocabulary and structures from each chapter, read and listened to model arguments, and planned, drafted, and revised your own supported argument in writing and in speech. Chapter 16 begins Unit IV, moving into cultural commentary, careful representation, and register, and continues to build on every system activated through Unit III.

Chapter Review

Section A — Structure Recognition

1. In the Reading Assessment passage, identify the sentence that states the thesis, the sentence that makes a comparison, the sentence that cites a statistic, and the sentences that describe the procedure.

2. In the Model Dialogue, identify which speaker uses each of the four Unit III systems, and in what order.

Section B — Self-Assessment

1. Which of the four systems — opinion, comparison, data commentary, or process description — is hardest for you to combine smoothly with the others?

2. Compare your Writing Workshop paragraph with the checklist. Did you include all four systems where relevant to your topic?

مُرَاجَعَة تَرَاكُمِيَّة — Cumulative review

Before moving to Unit IV, confirm that you can comfortably combine: opinion and qualification (Ch. 11); comparison, elatives, and interpretation (Ch. 12); statistics and data commentary (Ch. 13); and passive process description with sequence connectors and status participles (Ch. 14). Unit IV will continue to build on all of these systems in cultural, professional, and academic contexts.

Exercise 3 (model answer): أَعْتَقِد أَنَّ المَكْتَبَة يَجِب أَن تَبْقَى مَفْتُوحَة لَيْلًا، لِأَنَّهَا أَكْثَر هُدُوءًا مِن غُرَف السَّكَن لِلدِّرَاسَة. تُشِير الإِحْصَاءَات إِلَى أَنَّ أَرْبَعِين بِالمِئَة مِن الطُّلَّاب يَدْرُسُون بَعْد مُنْتَصَف اللَّيْل.

Reading Assessment — Comprehension

  1. The writer's thesis is that the scholarship-application process needs real simplification, even though the university has improved some aspects recently.
  2. The writer cites that nearly half of applications are rejected due to missing paperwork rather than failure to meet basic conditions, supporting the claim that the process itself is the problem, not the applicants.
  3. The writer compares the current system to a simplified electronic system used at other universities, concluding that the alternative is clearer and less complicated.
  4. The writer identifies the list of required documents as the main problem and proposes that the university review that list, since it causes most rejections.

Listening Assessment

  • The speaker's thesis is that the course-registration system needs reconsideration, even though it has improved in recent years.
  • The speaker cites that twenty percent of students do not get their first-choice courses, supporting the claim that the system still has a real problem.
  • The speaker compares the system to one used at other universities that allows early registration for high-achieving students, showing that the alternative is more flexible.
  • The speaker proposes changing the step in which registration priority is determined.

Chapter Review — Model responses

Section A.1: Thesis: the opening sentence with مِن وِجْهَة نَظَرِي. Comparison: the sentence comparing the current system to the electronic system used elsewhere. Data: the sentence with تُشِير الإِحْصَاءَات إِلَى أَنَّ. Process description: the sentences beginning with أَوَّلًا and ثُمَّ.

Section A.2: هِبَة uses the thesis, data, comparison, and process-description systems, in that order, while يُوسُف's turns function as follow-up questions that prompt each new system.

Section B: Open-ended self-assessment; any honest, specific response identifying one system and a concrete plan to strengthen it is acceptable.

Looking Ahead

Chapter 16 begins Unit IV: التَّعْبِير المُتَقَدِّم وَالمَشْرُوع (Advanced Expression and Project). It moves into cultural commentary, careful representation, and register, continuing to build on the opinion, comparison, data, and process-description systems consolidated in Unit III.

مَا الَّذِي تَسْتَطِيعُ فِعْلَهُ الآن — What you can do now

You can now build a complete supported argument in MSA: stating and qualifying a thesis, comparing options, citing and interpreting evidence, and, where relevant, describing a formal procedure impersonally. Unit IV will draw on all of these systems as you move into cultural interpretation, mediation, research, and a final B2 portfolio.

الثَّقَافَة وَالهُوِيَّة وَالتَّفْسِيرChapter 16: Culture, Identity, and Interpretation

Chapter 16 opens Unit IV with cultural commentary, careful representation, and register, building directly on the argumentation and evidence skills consolidated in this chapter.
