Correct Answer: C
Why this is correct: In this sentence, ought to means it is the right or sensible thing to do, and should means exactly that.
Tips: Memory trick: your teacher says you 'should' study and you 'ought to' study - same friendly advice.
Why the other options are wrong:
- D: could means being able to or having the chance to, not the sense of it being the right thing.
- B: must means have to, with no choice - that is stronger than the gentle advice in 'ought to'.
- A: might means maybe or possibly, which is about chance, not about the right thing to do.
Key Vocabulary:
- ought to = should = the right thing to do
- junk food = unhealthy food
Correct Answer: B
Why this is correct: Accuracy is a direct synonym of precision - both mean being exact and correct with no mistakes.
Tips: Memory trick: a 'precise' answer and an 'accurate' answer are both spot-on and correct.
Why the other options are wrong:
- A: truth means what is true or real, which is about honesty, not about measuring exactly.
- C: detail means the small parts or specifics - fits the topic, but it does not mean being exact.
- D: reality means what actually exists, a different idea from taking careful, exact measurements.
Key Vocabulary:
- precision = accuracy = being exact
- reliable = can be trusted
Correct Answer: B
Why this is correct: Both personnel and staff describe the people employed to work somewhere - pick either and the sentence reads the same.
Tips: Memory trick: 'personnel' sounds like 'persons' - and the 'staff' are the persons who work there.
Why the other options are wrong:
- C: people just means persons in general, which is too broad for the workers of one place.
- D: crew means a group working together, usually on a ship, plane, or hands-on job, not office employees.
- A: team means a group working together on a shared task, which is narrower than all the workers of a place.
Key Vocabulary:
- personnel = staff = the workers
- administrative = office and management
Correct Answer: C
Why this is correct: When the sentence says abnormal, it means not normal or out of the ordinary, and unusual is another way to say that.
Tips: Memory trick: 'ab-' at the start means 'away from' - abnormal is away from normal, which is unusual.
Why the other options are wrong:
- B: rare means happening very seldom - abnormal weather can happen often, so rare is not a perfect match.
- D: special means better or different in a good way, but abnormal weather is not a good thing.
- A: isolated means alone or separate, or a one-off event, which does not mean 'not normal'.
Key Vocabulary:
- abnormal = unusual = not normal
- patterns = repeated shapes or trends
Correct Answer: A
Why this is correct: The sentence uses seemingly to mean 'it appears to be so', and apparently has the same meaning.
Tips: Memory trick: 'seem' and 'appear' are twins - so 'seemingly' and 'apparently' both mean 'looks like it'.
Why the other options are wrong:
- B: clearly means with no doubt at all - that is too certain, while 'seemingly' leaves room for doubt.
- C: evidently means shown by clear evidence, which is more sure than something that just seems true.
- D: supposedly means people say so but it may not be true, adding doubt about others' claims, not about appearance.
Key Vocabulary:
- seemingly = apparently = it appears so
- deadline = final date
Correct Answer: B
Why this is correct: Here, deduce means to work something out by reasoning from the facts, and determine shares this meaning of establishing an answer, so it is correct.
Tips: Memory trick: a detective 'deduces' the answer and 'determines' the truth - both mean working it out from clues.
Why the other options are wrong:
- C: conclude looks very close, but it means to form a final opinion or judgement, while deduce and determine are about working out a definite fact.
- A: assess means to judge the value or quality of something, not to figure out a fact like a date.
- D: calculate means to work out using numbers or maths, which is narrower than reasoning from findings.
Key Vocabulary:
- deduce = determine = work out from facts
- excavation = careful digging
