That's it.

Close — here's the idea.

Count the gaps, not the trees. Between the 1st and 6th tree there are 5 gaps (not 6), and each gap is 4 metres, so 5 × 4 = 20 metres. Mixing up gaps and objects is the classic 'fence-post' slip these questions look for.

That's it.

Close — here's the idea.

First find one muffin's share: 3 ÷ 12 = ¼ cup each. Then 20 × ¼ = 5 cups. (Or scale up: 12 muffins to 20 is ×⁵⁄₃, so 3 × ⁵⁄₃ = 5.) Finding the 'per one' amount is the reliable move for these.

That's it.

Close — read the last line again.

“She forgot the climb at once” tells us the view replaced her tiredness — the mood turns from ache to wonder. Regret, the walk home and boredom are never mentioned, so the text doesn't support them. Inference questions reward the reading the words actually back up.

That's it.

Close — use the clues around the word.

The surrounding clues — “swaying with every gust” and “no one trusted it to hold their weight” — point to weak or unsteady. When a word is unfamiliar, the nearby words usually pin down its meaning.

That's it.

Close — line them all up first.

Chain the clues into one order: Dev before Ada, Ada before Ben, Ben before Cara → Dev, Ada, Ben, Cara. Dev is first. Building the full order before choosing keeps these puzzles from tripping you up.

That's it.

Close — look for what breaks the link.

Sam assumes the socks cause the wins. If the team also wins wearing other socks, the socks clearly aren't what makes the difference — that breaks the cause-and-effect Sam is relying on. The other options don't test whether the socks actually matter.
