Exactly right.

Close — first work out how many pancakes one egg makes.

3 eggs make 12 pancakes, so 1 egg makes 12 ÷ 3 = 4 pancakes. To make 20 pancakes you need 20 ÷ 4 = 5 eggs. Finding the amount for one first turns most rate problems into a single division.

Yes — well read.

Close — look at what she does, and at that last line.

Maya is in real pain but “did not slow down”, and we are told “second place was not why she had trained” — so she is aiming to win, not merely to finish. Inference questions ask you to read the clues in a character’s actions rather than wait for the text to state the answer.

That’s it.

Close — place them in order one clue at a time.

“Ahead” means earlier. Priya is before Sam; Sam is before Toby; Toby is before Ana. Lining those up gives the order Priya, Sam, Toby, Ana — so Ana finished last.

Exactly right.

Close — start from the total of all five numbers.

If the mean of five numbers is 14, their total is 5 × 14 = 70. The four given numbers add to 10 + 12 + 16 + 18 = 56. The fifth number is 70 − 56 = 14. Turning an average back into a total is the key move.

Yes — you caught the tone.

Close — would someone who was pleased mutter?

The quotation marks around ‘improvement’ and the exaggerated “thrilled” are sarcasm — Dad means the opposite of what he says. Muttering, and complaining that the 8:15 will “disappear for good”, show he is really annoyed. Tone questions turn on how something is said, not only the words.

That’s it.

Close — what has to be true for the plan to work?

The argument leaps from “hold it on Saturday” to “more parents can come”. That only follows if more parents are actually free on Saturdays than on school days — an unstated assumption the argument depends on. If it were not true, the reason would fall apart.

Spot on.

Close — the second discount comes off the new price, not the original.

25% off $80 leaves $60 (80 × 0.75). Then 10% off $60 leaves $54 (60 × 0.9). You cannot simply add 25% + 10% = 35% to get $52 — the second discount applies to the already-reduced price, not the original $80.

Yes — nicely worked out.

Close — let the rest of the sentence define the word for you.

The clue is right there: “neither side would give any ground, and the talks could go no further.” That describes a deadlock — a point where no progress is possible. In vocabulary-in-context questions, the surrounding words usually explain the hard one.

That’s it.

Close — stick only to what the two facts force to be true.

If every choir member can read music, then anyone who cannot read music cannot be a member — so Jordan is not in the choir. This is valid reasoning. The other options add facts we were never given.

Exactly right.

Close — more taps should mean less time, not more.

Three taps take 40 minutes, so the whole job is 3 × 40 = 120 “tap-minutes” of work. Five taps share that same work: 120 ÷ 5 = 24 minutes. Because more taps fill faster, the answer must be less than 40 — this is inverse proportion.

Yes — that’s the main idea.

Close — which idea does most of the paragraph support?

The paragraph sets honey aside in the first line (“more than make honey”) and spends the rest explaining pollination and why it matters to our food. That is its main point. Option A is mentioned only to be moved past, so it cannot be the main idea.

Impressive — that’s real spatial thinking.

Close — which small cubes sit on an edge but not a corner?

A small cube shows two painted faces only where two painted sides meet — along the edges of the big cube, but not at the corners (corners show three). A cube has 12 edges, and with three small cubes per edge, only the middle cube of each edge has exactly two painted faces: 12 × 1 = 12.

Spot on.

Close — find the width first, using the perimeter.

Call the width w; the length is 3w. The perimeter is 2 × (w + 3w) = 8w = 64, so w = 8 cm and the length is 24 cm. The area is 8 × 24 = 192 cm². Always find the side lengths before reaching for the area.

Yes — you felt the mood.

Close — picture what each comparison makes you feel.

Silence worn “like a heavy coat” makes the quiet feel weighty and close, and footsteps “like an apology” suggest people feel they should not disturb it. Together the images build an uneasy, oppressive stillness — not warmth or cheer. Figurative language is chosen for the mood it creates.

That’s it.

Close — start with the friend you know the most about.

Liam owns neither the fish nor the dog, so Liam must own the cat. That leaves the dog and the fish for Noah and Ava. Ava does not own the fish, so Ava owns the dog — and Noah owns the fish. Everything is fully determined.

Exactly right.

Close — what fraction of the whole class comes by bus?

If ⅔ walk, then ⅓ of the class are “the rest”. A quarter of that third come by bus: ¼ × ⅓ = 1/12 of the whole class. If 1/12 of the class is 3 students, the class has 3 × 12 = 36 students. Check: 24 walk, 12 are the rest, and 3 of those take the bus.

That’s it.

Close — “some” means at least a few, not “all”.

Every painting in the exhibition is for sale, and some of them are by local artists — so some of the paintings for sale must be by local artists. Option A says “every”, which claims more than we are told; C reverses the statement; D contradicts it.
