Question 1
The shop had many customers last Monday.
Complete the sentence: The workers busy last Monday.
- are
- were (correct answer)
- was
- will be
Explanation: When a sentence describes something that happened in the past, the verb must match that time — this question is testing your understanding of past tense verbs and subject-verb agreement.
The passage tells us the shop had many customers "last Monday," which signals we are talking about the past. The subject of our sentence is "the workers," which is plural (more than one person). To describe what the workers were doing in the past, you need a past tense verb that matches a plural subject. That word is were — making B) were the correct answer. "The workers were busy last Monday" fits perfectly because it is past tense and agrees with the plural subject.
Now let's look at why the other choices don't work. A) are is present tense, meaning it describes right now, not last Monday. Using "are" would incorrectly suggest the workers are busy at this moment. C) was is also past tense, but it is used only with singular subjects — one person or thing, like "she was" or "the manager was." Since "the workers" refers to multiple people, "was" does not agree with the subject. D) will be is future tense, meaning something that hasn't happened yet, which directly contradicts "last Monday."
A helpful tip: look for time clue words in the sentence. Words like yesterday, last week, last Monday, or ago signal past tense. Once you spot them, ask yourself — is the subject singular or plural? Singular gets was; plural gets were.
Question 2
It is 1:00 p.m. Lee's lunch break ended at 12:30. His food box is empty.
Which sentence best tells what happened?
- Lee ate lunch earlier today. (correct answer)
- Lee eats lunch earlier today.
- Lee is eating lunch earlier today.
- Lee will eat lunch earlier today.
Explanation: When a question asks you to pick the sentence that "best tells what happened," you're being tested on verb tense — the form of a verb that shows when something occurred. Look at the clues in the passage: it is currently 1:00 p.m., the lunch break ended at 12:30, and the food box is empty. All of this tells you the eating is finished and in the past.
Choice A says "Lee ate lunch earlier today." The word ate is past tense, meaning the action is already done. This matches the passage perfectly — lunch ended 30 minutes ago, so A is your correct answer.
Choice B says "Lee eats lunch earlier today." The word eats is present tense, used for habits or things happening right now. Saying someone "eats earlier today" is grammatically awkward and doesn't communicate a completed event — it creates confusion about when it happened.
Choice C says "Lee is eating lunch earlier today." This is present progressive tense, meaning the action is happening right now, in progress. But we know lunch is over, so this contradicts the passage entirely.
Choice D says "Lee will eat lunch earlier today." The word will eat is future tense — it describes something that hasn't happened yet. This directly contradicts the passage, since the lunch already occurred.
A helpful tip: before picking your answer, ask yourself, "Did this already happen, is it happening now, or will it happen later?" Match that to the correct tense — past, present, or future — and you'll avoid these traps every time.
Question 3
Mia went to the store yesterday. The store was closed, so she came home without milk.
Which sentence is correct?
- Mia did not buy milk yesterday. (correct answer)
- Mia did not bought milk yesterday.
- Mia does not buy milk yesterday.
- Mia will not buy milk yesterday.
Explanation: When a sentence describes something that happened in the past, you need to use the simple past tense. A key signal word here is "yesterday" — whenever you see "yesterday" in a sentence, the verb must be in past tense form.
Answer A is correct: "Mia did not buy milk yesterday." This sentence is properly built using the past tense helper verb "did not" (the negative past form of "do"), followed by the base form of the main verb "buy." This is the standard English pattern for negative past-tense sentences: did not + base verb.
Answer B, "Mia did not bought milk yesterday," is a very common mistake. When you use "did not," the main verb must stay in its base form — "buy," not "bought." You never combine "did not" with a past-tense verb. Saying "did not bought" is like doubling up the past tense, which is incorrect.
Answer C, "Mia does not buy milk yesterday," mixes up tenses. "Does not" is present tense, but "yesterday" signals the past. These two cannot go together — "does not" is used for habits or facts happening now, not completed past events.
Answer D, "Mia will not buy milk yesterday," makes no logical sense. "Will not" points to the future, but "yesterday" points to the past. You cannot use future tense to describe something that already happened.
A useful tip to remember: "yesterday" = past tense, always. When you spot "yesterday" in a sentence, look for "did" or another past-tense signal — and make sure the main verb stays in its base form after "did not."
Question 4
Today is Wednesday. Omar fixed the sink on Tuesday.
Which note correctly tells when Omar did the work?
- I fixed the sink last month.
- I fixed the sink yesterday. (correct answer)
- I will fix the sink tomorrow.
- I fix the sink every Tuesday.
Explanation: When a question asks you to match when something happened to the right time word, start by anchoring yourself to today's date. The passage tells you today is Wednesday and Omar fixed the sink on Tuesday — that means the work happened one day before today.
The word "yesterday" means the day before today, so if today is Wednesday, yesterday was Tuesday. That makes B ("I fixed the sink yesterday") the correct note — it accurately describes when the work was done.
Now look at why the other choices miss the mark. A says "last month," which would mean the work happened weeks ago — not just one day ago. That's too far back in time. C says "I will fix the sink tomorrow," which points to the future, but Omar already completed the work — it's done. D says "I fix the sink every Tuesday," which suggests a repeated habit, like something Omar does regularly every week. The passage only tells us about one specific time he fixed it, not a routine.
A helpful strategy: whenever you see time words like yesterday, tomorrow, last week, or every day, think about three categories — past (already happened), future (hasn't happened yet), and repeated habit (happens regularly). Then match the situation in the passage to the right category. Here, the work is finished and recent — just one day ago — so you need a past word that means "the day before today." That's your signal to choose B every time.
Question 5
Today is Friday. Tariq paid his bill on Wednesday.
Which sentence can Tariq say today?
- I pay the bill two days ago.
- I paid the bill two days later.
- I paid the bill two days ago. (correct answer)
- I will pay the bill two days ago.
Explanation: When a question asks you to pick the right sentence, check two things: the verb tense and the time words. These must match each other and match the situation in the passage.
Here, Tariq paid his bill on Wednesday, and today is Friday — so the bill was paid two days ago, in the past. That means the correct sentence needs a past-tense verb and a time word that points backward. Choice C — "I paid the bill two days ago" — gets both right. "Paid" is the past tense of "pay," and "ago" means time that has already passed. This is your answer.
Now let's look at why the others fail. Choice A says "I pay the bill two days ago" — "pay" is present tense, but "ago" signals the past. These two fight each other; you can't use a present-tense verb with a past time word. Choice B says "I paid the bill two days later" — "paid" is correct, but "later" points forward in time, not backward. "Later" is used for future events, so this sentence has the wrong direction. Choice D says "I will pay the bill two days ago" — "will pay" is future tense, which completely contradicts "ago." You cannot be planning to do something that already happened.
A good tip to remember: "ago" always pairs with past tense, and "later" always pairs with future tense. Matching your verb tense to your time word is the fastest way to catch errors like these.
Question 6
Rosa's note says, "Yesterday: miss the bus; walk to work."
Which sentence correctly reports both actions?
- Yesterday, Rosa misses the bus and walks to work.
- Yesterday, Rosa missed the bus and walk to work.
- Yesterday, Rosa miss the bus and walked to work.
- Yesterday, Rosa missed the bus and walked to work. (correct answer)
Explanation: When a sentence describes actions that happened in the past, every verb in that sentence must be in the past tense. This question tests whether you can keep verb tenses consistent across a sentence that contains two actions joined by "and."
Rosa's note tells us both things happened yesterday — that's a past-time signal. The two verbs you need to put in past tense are "miss" and "walk." Their past tense forms are missed and walked. A correct sentence uses both: "Yesterday, Rosa missed the bus and walked to work." That's choice D, and it's the only option where both verbs are properly in past tense.
Here's where the wrong answers go off track. Choice A uses "misses" and "walks" — those are present tense forms. They describe what someone does regularly, not what happened yesterday. Choice B gets the first verb right ("missed") but leaves the second verb as "walk," which is the base form, not past tense. Mixing a past tense verb with a base form is a common error. Choice C makes the opposite mistake — it uses the base form "miss" for the first verb but correctly uses "walked" for the second. Again, only one verb is in past tense when both need to be.
A quick strategy to remember: whenever a sentence has two or more verbs joined by "and," check each one individually. It's easy to fix the first verb and forget the second. Scan every verb in the sentence and ask yourself, "Does this match the time signal?"
Question 7
Today is Monday. Sam visited the clinic on Friday.
Which sentence tells what Sam did?
- Last week, Sam goes to the clinic.
- Last week, Sam will go to the clinic.
- Last week, Sam went to the clinic. (correct answer)
- Last week, Sam go to the clinic.
Explanation: When a sentence describes something that already happened in the past, the verb must be in the past tense. The passage tells you today is Monday and Sam visited the clinic on Friday — that visit is over, so any sentence describing it needs a past-tense verb.
"Went" is the correct past tense of the verb "go," which makes C the right answer. "Last week, Sam went to the clinic" uses proper grammar and matches the timeline in the passage.
Here's why the other choices miss the mark. A says "Sam goes to the clinic," which uses present tense — "goes" describes something happening now or regularly, not something that already happened last week. B says "Sam will go to the clinic," which is future tense — "will go" describes something that hasn't happened yet, but Sam's visit is already in the past. D says "Sam go to the clinic," which is missing the correct verb form entirely — you can't use the base form "go" after a subject like "Sam" without adding the right ending or helper word; it's grammatically incomplete.
A helpful tip: when a question asks what someone did, look for a verb ending in -ed or an irregular past-tense form. "Go" is irregular, meaning it doesn't follow the -ed pattern — its past tense is "went," not "goed." A short list of common irregular verbs (go→went, see→saw, eat→ate) is worth memorizing, as these appear often on reading and grammar questions at this level.
Question 8
A supervisor asks, "When did you start this job?" The worker began one month before today.
- I start this job last month.
- I started this job next month.
- I started this job last month. (correct answer)
- I will start this job last month.
Explanation: When answering a question like this, ask yourself two things: when did the action happen, and which verb tense matches that time? Here, the worker started the job one month ago — in the past — so you need a past tense verb.
The correct choice is C, "I started this job last month." The word started is the simple past tense of start, which is exactly right for something that happened before today. The phrase last month also correctly signals the past, so both the verb and the time word agree perfectly.
A is wrong because start is the present tense — it describes something happening now or as a habit (like "I start work at 9 a.m."). Using it with last month creates a mismatch between the verb and the time.
B uses started correctly as a past tense verb, but next month points to the future, not the past. Saying "I started this job next month" is a contradiction — you cannot have started something in the future.
D uses will start, which is future tense, meaning the job hasn't happened yet. Pairing a future verb with last month makes no sense — it's the opposite of what the situation describes.
A helpful tip to remember: match the verb tense to the time clue in the sentence. Words like last week, yesterday, and ago always call for past tense. Words like tomorrow and next week call for future tense. Spotting those time clue words first will guide you to the right verb every time.
Question 9
Today is Tuesday. Ana cleaned the office on Monday.
Which sentence can Ana write today?
- Yesterday, I clean the office.
- Yesterday, I cleaned the office. (correct answer)
- Tomorrow, I cleaned the office.
- Every day, I cleaned the office.
Explanation: When you see a question like this, ask yourself two things: When did the action happen? and Does the time word match the verb tense? These two pieces must agree for a sentence to be correct.
The passage tells you today is Tuesday and Ana cleaned the office on Monday — that means the cleaning happened yesterday, and it is already finished. In English, actions that are completed in the past use the past tense, which usually adds -ed to the verb. So "cleaned" is the correct verb form, and "yesterday" is the correct time word. That makes B — "Yesterday, I cleaned the office" the right answer. The time word and the verb tense match perfectly.
Here is why the other choices fail. A uses "yesterday" correctly, but writes "I clean" instead of "I cleaned." This is present tense, not past tense — it does not show that the action is finished. C uses "cleaned" correctly, but pairs it with "tomorrow," which points to the future. You cannot use a past-tense verb to describe something that has not happened yet — those two ideas conflict. D says "every day," which suggests a habit or routine, but "cleaned" is simple past, describing one specific completed event, not something Ana does repeatedly.
A helpful tip: always check both the time word and the verb in the sentence. If one points to the past and the other points to the present or future, the sentence is broken. Train yourself to match them like a lock and key.
Question 10
A coworker says, "I worked late last night."
Which question asks about that past action?
- Do you work late last night?
- Did you worked late last night?
- Were you work late last night?
- Did you work late last night? (correct answer)
Explanation: When asking about something that happened in the past, English uses a special helping verb: did. The word "did" already carries the past tense, so the main verb that follows it must stay in its base (simple) form — no "-ed" ending needed.
That rule is exactly what this question tests. The coworker worked late last night, so your question needs to ask about a completed past action using "did" + the base form of the verb.
Choice D — "Did you work late last night?" — gets this exactly right. "Did" signals the past, and "work" stays in its base form. This is the correct answer.
Now look at why the others fail. Choice A uses "do" instead of "did." The word "do" is present tense, so "Do you work late last night?" mixes a present-tense helper with a past time expression — that clash makes it grammatically wrong. Choice B is close but has a critical error: "Did you worked late last night?" adds "-ed" to "worked." Since "did" already handles the past tense, adding "-ed" doubles up — you can't have both. Choice C uses "were," which is a past form of "be," not a helper for action verbs. "Were you work late last night?" incorrectly tries to build a past question the way you would for a state of being, not an action.
A quick tip to remember: whenever you form a past yes/no question with an action verb, always use did + base verb. If you see "-ed" after "did," that's a trap — the answer is wrong.
