Class 9 English Kaveri Chapter 4: Modal Auxiliaries Important Questions & Answers (2024-25 CBSE)

Modal auxiliaries occupy a permanent space in CBSE Class 9 English assessments because they test both grammatical knowledge and communicative competence. The rationalized 2024-25 syllabus emphasizes functional English—using modals correctly in real-world scenarios like making requests, giving permission, expressing obligation, and stating ability. In board exams, modal questions appear across all three marks—MCQs test recognition, short-answers test application, and long-answers test discourse construction. The CBSE evaluates not just whether you choose the correct modal, but why it's correct in that context. Chapter 4 of Kaveri textbook isolates modals into three functional groups: (1) ability & permission (can/could/may/might), (2) obligation & advice (should/must/ought to), and (3) prohibition & necessity. Mastering these distinctions ensures you score in vocabulary, grammar, and comprehension sections simultaneously. Students who neglect modal practice often lose 8–12 marks in board exams simply by confusing 'can' with 'may' or 'should' with 'must'—errors that reflect incomplete understanding rather than careless mistakes.

MCQs test quick recognition of correct modal forms and their meanings. These questions appear in all CBSE Class 9 papers and require you to identify the contextually appropriate modal in a single attempt. **Question 1:** Which modal expresses permission in formal situations? (a) can (b) may (c) might (d) could **Answer:** (b) may — 'May' is the formal, polite modal for seeking permission. 'Can' is informal; 'might' and 'could' express possibility. **Question 2:** Fill the blank: "You _______ finish your homework before playing." (a) could (b) must (c) might (d) can **Answer:** (b) must — The sentence expresses obligation/necessity. 'Must' is the only option that conveys required action. **Question 3:** Which modal suggests possibility or uncertainty? (a) should (b) might (c) must (d) ought to **Answer:** (b) might — 'Might' expresses possibility with lower certainty. 'Must' is certainty; 'should' and 'ought to' express obligation. **Question 4:** Choose the correct negative form: "You _______ touch the electrical wire." (a) shouldn't (b) mightn't (c) can't (d) mustn't **Answer:** (d) mustn't — 'Mustn't' (must not) expresses prohibition with strong obligation. 'Can't' is also correct but 'mustn't' better conveys safety rules. **Question 5:** What does 'could' express in: "When she was young, she _______ play the piano beautifully"? (a) present ability (b) permission (c) past ability (d) obligation **Answer:** (c) past ability — 'Could' as the past tense of 'can' shows ability that existed in the past.

Short-answer questions require you to explain the meaning or context of a modal, often within 30–40 words. These test comprehension and the ability to justify your answer. **Question 1:** Distinguish between 'can' and 'may' in English grammar. Give one example of each. **Answer:** 'Can' expresses ability or informal permission ("You can borrow my pen"), while 'may' expresses formal permission or possibility ("May I ask a question?"). 'Can' is casual; 'may' is polite and official. **Question 2:** Rewrite the sentence using an appropriate modal: "It is possible that it will rain tomorrow." **Answer:** "It might rain tomorrow" or "It may rain tomorrow." Both modals ('might' and 'may') express possibility. 'Might' carries slightly lower certainty than 'may'. **Question 3:** What is the difference between 'must' and 'should'? Provide a sentence for each. **Answer:** 'Must' expresses strong obligation or necessity ("You must wear a helmet while riding"), while 'should' expresses weak obligation, advice, or recommendation ("You should study regularly"). 'Must' is mandatory; 'should' is advisory. **Question 4:** Fill in the blanks and explain your choice: (a) "Employees _______ arrive on time." (should/must) (b) "You _______ enter without permission." (can't/shouldn't) **Answer:** (a) 'must'—workplace rules demand strict compliance. (b) 'can't'—expresses inability/prohibition. 'Can't' is stronger and means it's not possible/allowed. **Question 5:** Convert this into a polite request using a modal: "Open the window." **Answer:** "Could you open the window?" or "Would you mind opening the window?" Using modals transforms a direct command into a courteous request, which is essential for formal communication.

These questions require deeper understanding—you must not only identify the correct modal but also explain its function within a sentence or discourse context. Expect to write 50–80 words. **Question 1:** Read the dialogue and identify the modals used. Explain why each modal is appropriate: Teacher: "Students, you **must** submit your projects by Friday. You **can** use the library resources freely. You **should** refer to the textbook too." Student: "**May** I ask for an extension?" **Answer:** The teacher uses 'must' (strict obligation for deadline), 'can' (permission/ability to access resources), and 'should' (advice/recommendation for study materials). The student uses 'may' (formal, polite request for permission). This variety reflects real classroom communication where different modals serve different communicative purposes—'must' ensures accountability, 'can' grants freedom, 'should' guides learning, and 'may' maintains respect. **Question 2:** Rewrite these sentences using appropriate modals, then explain the change in meaning: (a) "It's possible that she arrives late." → "She _______ arrive late." (b) "You have no choice but to attend the meeting." → "You _______ attend the meeting." **Answer:** (a) "She might/may arrive late" (possibility instead of certainty). (b) "You must attend the meeting" (obligation instead of option). Using modals makes the sentences grammatically correct and stylistically appropriate—'might' softens certainty, 'must' emphasizes unavoidability. **Question 3:** Explain the grammatical error in each sentence and correct it: (a) "You can to go now." (b) "She mustn't to study hard." **Answer:** (a) Error: 'can' cannot be followed by 'to + verb'. Correct: "You can go now." (b) Error: Double modal structure is incorrect. Correct: "She must study hard" or "She has to study hard." Modals are followed directly by the base form of the verb, not by 'to'. **Question 4:** Write three sentences using 'ought to' to express advice, obligation, and expectation respectively. **Answer:** (1) Advice: "You ought to exercise regularly for good health." (2) Obligation: "Children ought to respect their elders." (3) Expectation: "The bus ought to arrive by 5 PM." 'Ought to' is formal and expresses moral or social duty, making it ideal for advice and strong recommendations.

Long-answer questions test your ability to construct extended responses using modals in realistic contexts. These typically require 120–150 words and may involve scenario-based writing or detailed explanations. **Question 1:** A friend invites you to a concert, but you have a school project deadline the next day. Write a response using appropriate modals to politely decline and suggest an alternative. **Full Solution:** "Dear [Friend's name], thank you for the invitation! I really appreciate it, but unfortunately I can't attend because I have a project deadline the next morning. However, I think we could plan another outing instead. Why don't we go to the concert next month? You should check the dates with the organizers. In the meantime, I could help you with any school work, and you might enjoy visiting the library with me this weekend. I know it might not sound as exciting as a concert, but we could make it fun. Please let me know what you think, and I hope you'll understand my situation. We must stay focused on our studies, but I assure you we'll have plenty of time for outings soon." *Analysis of modals:* 'can't' (inability), 'could' (possibility), 'should' (advice), 'might' (uncertainty), 'must' (obligation). This response balances formality with warmth while expressing constraints and alternatives—essential skills for Class 9 comprehension and writing tasks. **Question 2:** Imagine you are a school principal writing instructions to staff about a new safety protocol. Draft a paragraph using at least 5 different modals, explaining what staff members must, should, can, and may do. **Full Solution:** "All staff members must adhere to the new safety protocol effective immediately. Teachers should conduct fire drills every month and must ensure all exit routes are clear. Students can participate voluntarily in these drills, though participation should be mandatory for safety awareness. Staff may report any safety concerns to the security team without delay. Visitors must sign the register before entering the campus. We should maintain a culture of responsibility where everyone takes ownership of campus safety. You ought to familiarize yourselves with the protocol by Friday. Students might face consequences if they ignore safety guidelines, so we must communicate this clearly. Teachers can request additional safety training sessions if needed. Following these guidelines, we can build a safer school environment for everyone." *Modal distribution:* 'must' (5 times—non-negotiable rules), 'should' (3 times—recommendations), 'can' (2 times—permission/ability), 'may' (1 time—formal permission), 'might' (1 time—consequences). This demonstrates sophisticated modal usage appropriate for formal institutional communication. **Question 3:** Compare and contrast the usage of 'can,' 'could,' 'may,' and 'might' by writing four sentences—one for each modal—in a scenario where a student asks a teacher for permission to leave class early. **Full Solution:** (1) "Can I leave class early?" (informal, direct, seeking ability/permission) (2) "Could I leave class early?" (polite past-form alternative, less direct) (3) "May I leave class early?" (formal, respectful, conventional in institutional settings) (4) "Might I leave class early?" (very formal, rare in spoken English, highly respectful) Register analysis: Sentence 1 is conversational; sentence 2 is polite but still casual; sentence 3 is the standard formal request in schools; sentence 4 is archaic or overly formal. In CBSE contexts, students must recognize that 'may' is the most appropriate for formal settings, while 'can' and 'could' suit informal environments. 'Might' is rarely used in contemporary English for this purpose.

**Question:** Read this scenario and answer the questions that follow. Raj is a Class 9 student preparing for his board exams. His parents suggest he join a tuition center, but Raj is unsure. His friend suggests, "You should definitely join—it will help you score better." His elder brother says, "You must focus on self-study first; tuition can be helpful later." His mother says, "You might regret not seeking professional guidance." His teacher says, "You can attend extra classes at school if you wish, but you ought to practice regularly at home too." **(a) Identify all modals in the scenario and categorize them by function (ability, permission, obligation, advice, possibility).** **(b) Rewrite each character's suggestion using a different modal that conveys a similar meaning.** **(c) What does this scenario teach you about the social nature of modals?** **Step-by-Step Solution:** **Step 1—Identify & Categorize:** Should (advice): Friend's suggestion Must (obligation): Brother's statement Can (ability/permission): Brother's statement, Teacher's statement Might (possibility): Mother's statement Ought to (advice/obligation): Teacher's statement **Step 2—Rewrite with Different Modals:** Friend: "You could benefit from joining a tuition center." (possibility instead of weak obligation) Brother: "You ought to prioritize self-study; tuition may help later." (obligation + possibility instead of obligation + ability) Mother: "You could regret not seeking help." (ability/possibility instead of possibility) Teacher: "You have the option to attend extra classes; you should practice regularly." (permission + weak obligation instead of ability + obligation) **Step 3—Social Nature of Modals:** Different speakers use different modals to reflect their relationship to Raj and their perspective on his choices. The friend uses 'should' (informal advice), the brother uses 'must' (authoritative guidance), the mother uses 'might' (expressing concern), and the teacher uses 'can' and 'ought to' (institutional support + moral guidance). This shows that modals carry social meaning—they signal power dynamics, intimacy, and communicative intent, not just grammar rules. In real communication, modal choice reflects your relationship to the listener and your certainty/urgency.
