Correct Answer: C
Why this is correct: Both responded and replied describe answering back to a message - pick either and the sentence reads the same.
Tips: Memory trick: you 'respond' to a text by 'replying' to it - both send an answer back.
Why the other options are wrong:
- A: spoke means talked out loud, but you cannot speak to an email - you write back to it.
- B: wrote means put words on paper or screen, which is general and misses the idea of answering the email.
- D: answered is very close in meaning, but it does not take 'to it' - we say 'replied to it', so replied fits the grammar.
Key Vocabulary:
- responded = replied = answered back
- urgent = needs quick action
Correct Answer: D
Why this is correct: In this sentence, declared means to state something officially for all to know, and announced means exactly that.
Tips: Memory trick: a referee 'declares' the winner and 'announces' it to the crowd - both make it official.
Why the other options are wrong:
- A: explained means to make something clear by giving reasons, not to make an official statement.
- B: claimed means to say something is true, but often without proof - the council is stating it as fact, not just claiming.
- C: insured means protected with insurance - the spelling looks close to 'ensured', but it does not mean to announce.
Key Vocabulary:
- declared = announced = stated officially
- supply = the amount provided
Correct Answer: B
Why this is correct: Proof means something that shows a fact is true; evidence carries the same meaning, so either word fits here.
Tips: Memory trick: in court you need 'proof' and 'evidence' - both show that something really happened.
Why the other options are wrong:
- A: support means help or backing, which is not the same as something that shows a fact is true.
- C: confirmation means something that makes an idea certain, but here she needs evidence, like a receipt, to prove she bought it.
- D: case means an argument or situation, not a single piece of proof.
Key Vocabulary:
- proof = evidence = shows it is true
- purchased = bought
Correct Answer: B
Why this is correct: When the sentence says capabilities, it means the things the phone can do, and features is another way to say that when talking about a product.
Tips: Memory trick: a phone's 'features' are its 'capabilities' - all the clever things it is able to do.
Why the other options are wrong:
- A: capacities looks almost the same as capabilities, but it means how much something can hold, not what it can do.
- C: elements means the basic parts something is built from, which is not the same as its special abilities.
- D: potentials means abilities that could happen in the future, but the phone's features already work now.
Key Vocabulary:
- capabilities = features = what it can do
- high-resolution = very clear and sharp
Correct Answer: C
Why this is correct: Greatly is a direct synonym of substantially - both mean by a large amount.
Tips: Memory trick: a 'substantial' meal and a 'great' increase are both big - the amount is large.
Why the other options are wrong:
- A: extensively means over a wide area or covering a lot of ground, not by a large amount.
- B: largely means mostly or mainly, which is about the main part, not about a big increase.
- D: broadly means widely or in a general way, which does not describe the size of the rise.
Key Vocabulary:
- substantially = greatly = by a large amount
- funding = money given
Correct Answer: A
Why this is correct: Here, deemed means considered or regarded as true by default, and since presumed means assumed to be true in the same way, it is the correct answer.
Tips: Memory trick: if silence means yes, you are 'deemed' to agree and 'presumed' to agree - both assume it for you.
Why the other options are wrong:
- B: estimated means roughly worked out with numbers, which does not fit being regarded as having agreed.
- C: supposed is close - it also means assumed - but presumed is the stronger, more formal match for 'deemed' in official rules.
- D: suspected means to think something, usually something bad, might be true, which does not fit here.
Key Vocabulary:
- deemed = presumed = taken to be true
- objections = reasons against
