Question 1

David is looking for a new apartment. He can pay $800 a month. He needs to live close to the bus stop. He wants to have a pet.

David finds an apartment that costs $900 a month, is far from the bus stop, and allows pets. Based on David's situation, which statement is MOST accurate?

  1. David needs to live far from the bus stop, so this apartment meets that requirement, and he can pay $900 without any problem.
  2. David can afford this apartment because he wants to pay more, and it meets his need to have a pet while being close to the bus stop.
  3. David can't afford this apartment and it doesn't meet his need to be near the bus stop, even though it matches what he wants for a pet. (correct answer)
  4. David wants to pay $800, so he can choose this apartment at that price, and he doesn't need to worry about the bus stop location.
Explanation: When reading a passage about someone's needs and wants, your job is to carefully separate what a person requires (a must-have) from what they simply prefer (a nice-to-have). David's situation gives you three key facts: he can pay up to $800, he needs to be near a bus stop, and he wants a pet. Now compare those facts to the apartment: it costs $900, it is far from the bus stop, and it allows pets. The apartment costs $100 more than David can afford — that's a problem. It is also far from the bus stop — that breaks his requirement. The only thing it gets right is allowing pets. So the most accurate statement is C: David cannot afford it, it fails his transportation need, and it only satisfies his pet preference. Choice A is wrong because it reverses David's need — he needs to live close to the bus stop, not far from it. Choice B is wrong for two reasons: David does not "want to pay more," and the apartment is far from the bus stop, not close. Choice D is wrong because David cannot simply choose to pay $800 for an apartment listed at $900 — the price is fixed by the landlord, not the renter. A useful strategy: when a passage lists someone's needs, make a quick mental checklist and test each answer choice against every item. Questions like this often contain answer choices that get one detail right but flip another — always check all the facts before choosing.

Question 2

Ana is talking to her classmate. She says: 'I need to study tonight, but I want to watch a movie with my family. I can do one or the other, but not both.'

What does Ana's statement reveal about her situation?

  1. Ana wants to study and needs to watch a movie, and she has the ability to do both activities at the same time tonight.
  2. Ana has a necessity (studying), a desire (watching a movie), and a limited ability that forces her to choose only one activity. (correct answer)
  3. Ana can study and can watch a movie, but she needs to choose the movie and wants to skip her studying for tonight.
  4. Ana needs to do both activities tonight and wants to find a way to complete them, but she lacks the ability to decide which one matters more.
Explanation: When reading comprehension questions ask you to analyze what a statement reveals, focus on the specific meaning of key words — especially modal verbs like "need," "want," and "can." These three words express very different things: need shows necessity, want shows desire, and can shows ability or possibility. In Ana's statement, each word carries a distinct meaning. She needs to study — that's an obligation or necessity. She wants to watch a movie — that's a personal desire. She can do one or the other, but not both — that's a limited ability that forces a choice. Answer B captures all three of these elements accurately, making it the correct answer. Answer A is wrong because it reverses Ana's words entirely — it claims she wants to study and needs the movie, which is the opposite of what she said. It also falsely states she can do both at the same time, which directly contradicts "not both." Answer C is wrong because it incorrectly says Ana needs to choose the movie and wants to skip studying. Nothing in her statement says she has already decided or prefers the movie. This answer invents information. Answer D is wrong because Ana clearly can decide — her problem isn't indecision about which matters more, it's simply that time limits her to one activity. She understands her situation; she just hasn't made the choice yet. A good strategy: always match each part of the answer choice back to the exact words in the passage. If any part of the choice contradicts or adds to the text, eliminate it.

Question 3

Carlos needs to wake up early tomorrow. He can set an alarm, but he wants to ask his sister to wake him up too.

Which sentence uses 'need to,' 'can,' and 'want to' correctly to summarize what Carlos is doing?

  1. Carlos needs to wake up early, can set an alarm, and wants to ask his sister to help him wake up. (correct answer)
  2. Carlos wants to wake up early, can't set an alarm, and needs to ask his sister to wake him up.
  3. Carlos can wake up early, needs to set an alarm, and wants to ask his sister to stop helping him.
  4. Carlos needs to set an alarm, can ask his sister for help, and wants to wake up late tomorrow.
Explanation: When a question asks you to "summarize" a passage using specific words, your job is to match each detail in the answer choice back to what the passage actually says. Pay close attention to what each modal verb means: need to = something necessary or required, can = something possible or able to be done, want to = something desired. Looking at the passage, three things are true about Carlos: (1) he must wake up early — that's a requirement; (2) he is able to set an alarm — that's a possibility; and (3) he desires to ask his sister for help — that's a wish. Answer A matches all three facts perfectly: "needs to wake up early" (requirement ✓), "can set an alarm" (possibility ✓), and "wants to ask his sister to help" (desire ✓). A is correct. Answer B is wrong for two reasons: the passage says Carlos needs to wake up early, not wants to, and it says he can set an alarm, not that he can't. Answer C incorrectly says Carlos can wake up early (it's a requirement, not just a possibility) and flips the meaning of asking his sister — the passage says he wants her to help, not stop helping. Answer D completely reverses the details: Carlos needs to wake up, not set an alarm, and he certainly doesn't want to wake up late — that contradicts the whole passage. Your study tip: when you see "need to," "can," and "want to," always ask yourself — Is this a requirement, an ability, or a wish? Matching the right modal to the right situation is the key to these questions.

Question 4

Maria is a new student at the adult learning center. She speaks a little English, but she does not speak Spanish at school. She wants to study math, and she needs to find a tutor.

Which sentence BEST describes Maria's situation using 'can,' 'can't,' 'want to,' and 'need to'?

  1. Maria can speak a little English, can't speak Spanish at school, wants to study math, and needs to find a tutor. (correct answer)
  2. Maria can't speak any English, wants to speak Spanish at school, needs to study math, and wants to find a tutor.
  3. Maria can speak a little English, wants to speak Spanish at school, can't study math, and needs to find a tutor.
  4. Maria can speak a little English, needs to speak Spanish at school, wants to study math, and can't find a tutor.
Explanation: When you see a question like this, your job is to match each modal phrase — can, can't, want to, and need to — to the correct fact from the passage. Think of it as a checklist: go sentence by sentence and ask, "Does the passage say this is an ability, an inability, a desire, or a necessity?" The passage gives you four clear facts: (1) Maria speaks a little English — that's an ability, so use can. (2) She does not speak Spanish at school — that's something she is not doing, so use can't. (3) She wants to study math — that's a desire, so use want to. (4) She needs to find a tutor — that's a necessity, so use need to. Answer A matches all four facts perfectly, making it the correct choice. Answer B is wrong in every detail — it says Maria can't speak any English (the passage says she can speak a little), and it swaps want to and need to for the wrong facts. Answer C correctly states she can speak a little English, but then incorrectly says she wants to speak Spanish at school and can't study math — neither of those facts appears in the passage. Answer D gets the English ability right but then says she needs to speak Spanish at school and can't find a tutor, which again contradicts the passage. A helpful strategy: before looking at the answer choices, reread the passage and write down the four key facts yourself. Then eliminate any answer that changes even one detail — on this type of question, every word matters.

Question 5

Which sentence is grammatically CORRECT and uses modal expressions properly for an English learner at a beginner level?

  1. She needing to practice English every day so she wants speak better at work.
  2. She need practice English every day so she cans speak better at work.
  3. She needs practice English every day so she can to speak better at work.
  4. She needs to practice English every day so she can speak better at work. (correct answer)
Explanation: When learning English grammar, two structures to master early are verb conjugation (matching the verb to the subject) and modal verbs (words like can, should, must that express ability or necessity). This question tests both at once. In English, the verb need changes form depending on the subject. With she/he/it, you add -s: she needs. When need is followed by another verb, you must use the infinitive form: need + to + base verb (needs to practice). The modal verb can is special — it never changes form and is always followed by a bare infinitive (base verb, no to): can speak, never can to speak or cans speak. Answer D — She needs to practice English every day so she can speak better at work — follows all these rules perfectly: needs to practice (correct infinitive structure) and can speak (correct modal + bare infinitive). Answer A fails immediately because needing is a gerund, not a conjugated verb — you cannot say she needing. It also incorrectly writes wants speak instead of wants to speak. Answer B uses need without the required -s for third-person singular (she need), and it incorrectly adds -s to the modal can, writing cans — modals never take -s endings. Answer C gets needs right but then incorrectly writes practice without to (needs practice instead of needs to practice), and adds to after can (can to speak), which is always wrong with modals. Remember this pattern: modal + base verb (no to, no -s) and need/want/have + to + base verb.

Question 6

A friend says to you: 'I can help you move on Saturday, but I can't stay all day.' What is your friend telling you?

  1. Your friend can stay all day Saturday but does not want to help with moving heavy things.
  2. Your friend wants to help you move and needs you to finish moving before Saturday afternoon.
  3. Your friend is unable to help you move at all and needs to stay home on Saturday.
  4. Your friend is able to help you for part of Saturday but is not able to be there for the entire day. (correct answer)
Explanation: When someone uses the word "but" in English, pay close attention — it signals a contrast between two ideas. The sentence "I can help you move on Saturday, but I can't stay all day" has two clear parts: something your friend can do, and something your friend cannot do. Your job is to hold both parts together. Your friend is saying two things: (1) they are willing and able to help you move, and (2) they have a limitation — they cannot be there for the whole day. This means they will be available for part of Saturday, just not from start to finish. That makes D the correct answer. It captures both pieces of information accurately. A is wrong because it reverses the meaning — your friend is willing to help with moving but cannot stay all day, not the other way around. B misreads the sentence by adding information that was never said. Your friend said nothing about needing you to finish before Saturday afternoon — that detail was invented. C is the opposite of what was said. Your friend clearly said "I can help you move," so saying they are unable to help at all directly contradicts the sentence. A useful strategy: when a sentence contains "but," underline both sides — what can happen and what cannot. Wrong answer choices often flip one side or completely ignore the other. On ESL questions like this, the trap is usually an answer that takes only half the sentence into account.

Question 7

Which sentence uses 'can't' CORRECTLY to express inability?

  1. She can't to understand the instructions because they are written in a language she does not know.
  2. She can't understand the instructions because they are written in a language she does not know. (correct answer)
  3. She not can understand the instructions because they are written in a language she does not know.
  4. She doesn't can understand the instructions because they are written in a language she does not know.
Explanation: When using modal verbs like can and can't in English, the rule is simple but important: the verb that follows must be in its base form (the plain, infinitive form without to). This question tests whether you know the correct structure for expressing inability. Answer B is correct because it follows the proper pattern: subject + can't + base verb. "She can't understand" is grammatically clean — can't does the work of negation, and understand stays in its base form. The reason given ("they are written in a language she does not know") also logically supports the idea of inability, making the whole sentence natural and correct. Answer A adds to after can't, giving you "can't to understand." This is a common mistake — learners sometimes confuse modal verbs with phrases like want to or need to, which do require to. Modal verbs (can, will, should, must) never take to before the next verb. Answer C places not between the subject and can, producing "She not can understand." In English, negation with modals attaches directly to the modal itself — you say cannot/can't, not not can. Answer D uses "doesn't can," combining two different ways of forming negatives at once. Doesn't is used to negate regular verbs (she doesn't walk), while can't negates modal verbs. You cannot mix them together. A helpful tip: whenever you see can, could, should, will, or must, always follow it with a bare base verb — no to, no doesn't, and keep the negative attached to the modal itself.

Question 8

Read the two sentences: (1) 'I want to eat pizza tonight.' (2) 'I need to eat something tonight.' What is the MAIN difference in meaning between these two sentences?

  1. Sentence 1 expresses an ability the speaker has, while Sentence 2 expresses a desire the speaker feels strongly.
  2. Sentence 1 expresses something the speaker must do, while Sentence 2 expresses something the speaker is able to do.
  3. Sentence 1 expresses a personal desire or preference, while Sentence 2 expresses a requirement or necessity. (correct answer)
  4. Both sentences express the same idea because 'want to' and 'need to' have the same meaning when talking about food.
Explanation: When learning English, one of the most important skills is understanding how individual words change the meaning of a sentence. This question tests your understanding of two very common verbs: want and need. "Want" describes something you desire or prefer — it's your personal wish, but it's not required. "Need" describes something necessary or required — you must have it or do it. Sentence 1 says "I want to eat pizza," meaning pizza is the speaker's preference, but they could choose something else. Sentence 2 says "I need to eat something," meaning eating is a requirement — perhaps the speaker is hungry and their body must have food. This makes C the correct answer: Sentence 1 expresses a personal desire, while Sentence 2 expresses a necessity. Choice A is wrong because neither sentence talks about ability (what someone can do). "Want" is not an ability word. Choice B reverses the meanings entirely — it claims "want to" means must and "need to" means able to, which is the opposite of what these words actually mean. Choice D is a common trap for beginners: just because both sentences discuss eating does not mean the words "want" and "need" mean the same thing. They have clearly different meanings in any context. A useful tip: watch for the words want, need, can, and must in English. These are called modal-like expressions, and each one signals something different — desire, necessity, ability, or obligation. Knowing the difference will help you on many ESL questions.

Question 9

A student says: 'I want to go to the library, but I can't find my library card.' What does this sentence tell us about the student?

  1. The student has a desire to go to the library but is unable to locate something necessary to do so. (correct answer)
  2. The student is required to go to the library and is able to find the library card easily.
  3. The student does not want to go to the library because the library card is missing from the bag.
  4. The student needs to go to the library and cannot go because the library is closed today.
Explanation: When reading a sentence like this, focus on two key parts: what the person wants and what is stopping them. The word "but" is your biggest clue — it signals a contrast between a desire and a problem. In this sentence, "I want to go to the library" clearly expresses a wish or desire. The second part, "but I can't find my library card," tells you something is missing that prevents the action. Putting these together, the student wants to go but cannot locate what is needed. That matches A perfectly — it captures both the desire and the obstacle without adding anything extra. B is wrong for two reasons: it says the student is required (not just wanting) to go, and it claims the card is found easily — the opposite of what the sentence says. C is wrong because the student does want to go to the library; this choice reverses the meaning entirely. It also incorrectly states the card is in a bag — the sentence never mentions a bag. D is wrong because it says the library is closed, which is never mentioned. The problem is a missing card, not a closed building. A helpful strategy: when a sentence has the word "but," always identify what comes before it (the goal or desire) and what comes after it (the obstacle or contrast). Exam questions often test whether you can separate the two without adding details that aren't there — stick only to what the sentence actually says.

Question 10

Look at this sentence: 'He   drive a car, but he   buy one because he doesn't have enough money.' Which words correctly complete the sentence?

  1. 'can' and 'can't' — because he has the ability to drive but lacks the ability to afford a car right now. (correct answer)
  2. 'can't' and 'needs to' — because he does not know how to drive and must save money to buy a car.
  3. 'wants to' and 'can' — because he desires to drive and is able to buy a car with his money.
  4. 'needs to' and 'can't' — because he is required to drive and is unable to do so without a car.
Explanation: When a sentence has two blanks testing different meanings, slow down and read the whole sentence for context clues before choosing. Here, the key phrase is "he doesn't have enough money" — that tells you exactly what the second blank must express: inability due to lack of funds. The word "can" expresses ability — something a person knows how to do. "Can't" is simply the negative form, meaning a person lacks that ability. The sentence tells us he is able to drive (he has the skill), but he is not able to buy a car (he lacks the money). That makes A — "can" and "can't" the correct choice. "He can drive a car, but he can't buy one because he doesn't have enough money" fits perfectly: one ability exists, the other does not. Choice B introduces "needs to," which expresses necessity or obligation, not ability — and it also wrongly claims he doesn't know how to drive, which the sentence never suggests. Choice C uses "wants to" (desire) and "can" (ability to buy), which actually contradicts the context clue about lacking money — if he could buy a car, the sentence wouldn't make sense. Choice D uses "needs to" and "can't" in a way that reverses the logic entirely, suggesting he's required to drive but can't, which ignores the money detail completely. A helpful tip: when you see "because" in a sentence, whatever follows is the reason — use it as your guide. Let that reason tell you which modal verb (can, can't, needs to, wants to) fits the blank before it.
