That’s it.

Close — answer from what the passage actually says.

The passage tells us she carried no lamp and lit no flame, which rules out lighting it. It then says she counted the ships and wrote down their names — she was keeping a record. Inference means using what the text states, not what a lighthouse is usually for.

That’s it.

Close — let the sentence decide the meaning.

“Slipped” has several meanings, but here the ships are moving past in the dusk, so it means moved quietly and smoothly. Vocabulary-in-context questions reward the meaning the sentence supports, not the most common one.

That’s it.

Close — the main idea is what every sentence supports.

Every sentence points to one idea: bees see colours differently, and that shapes which flowers they choose. Options A and D are single details, and B is an overstatement — none of them is the whole point of the passage.

That’s it.

Close — follow what the passage tells us about red.

The passage says bees rarely visit red flowers and advises lavender over red roses, so red roses would draw fewer bees than lavender. It never says roses can’t grow, and it states bees see red as dull, not bright.

That’s it.

Close — think about what is being grasped.

“Grasp” can mean to hold something in your hand, but here a student is grasping an explanation, so it means understand. The clue is the context — a clear explanation a student could follow.

That’s it.

Close — read the clues the writer leaves.

The empty road, Sara’s sigh, and her setting off on the “long walk to school” instead of waiting all point to the bus having already gone. Nothing says she planned to walk, and the wet timetable shows rain, not sun. Inference means reading the clues, not just the stated words.

That’s it.

Close — find the total before you subtract.

First find how many muffins there are: 6 trays × 8 = 48. Then take away what was sold: 48 − 34 = 14 left. The trap answer 82 comes from adding 48 and 34; do the multiplication first, then the subtraction.

That’s it.

Close — add both items before taking the change.

Add the two prices first: $12 + $3.50 = $15.50. Then subtract from the $20 note: $20 − $15.50 = $4.50 change. Adding both items before you subtract avoids the common slip of paying for only one.

That’s it.

Close — the question asks what is left, not what was eaten.

Together they eat 3 + 2 = 5 slices out of 8, so 5/8 is gone. That leaves 8 − 5 = 3 slices, which is 3/8 of the pizza. The trap answer 5/8 is the part eaten, not the part left.

That’s it.

Close — add the hour and the minutes in two steps.

Add the hour first: 2:45 → 3:45. Then add the 40 minutes: 15 minutes reaches 4:00, and 25 more makes 4:25 pm. Splitting the time into the hour and the minutes keeps it simple.

That’s it.

Close — start by imagining they were all the same.

If all 7 vehicles were motorbikes, that would be 7 × 2 = 14 wheels — but there are 22, which is 8 extra. Each car has 2 wheels more than a motorbike, so 8 ÷ 2 = 4 cars. Check: 4 cars and 3 motorbikes give 16 + 6 = 22 wheels.

That’s it.

Close — find one book first, then scale up.

Find the weight of one book: 900 ÷ 3 = 300 grams each. Then 5 books weigh 5 × 300 = 1500 grams. Working out the single value before multiplying is the key step.

That’s it.

Close — chain the clues into one line before choosing.

“Mo before Kim” and “Kim before Lena” give Mo, Kim, Lena in that order. “Sam after Lena” puts Sam last. Joined up, the finish order is Mo, Kim, Lena, Sam. Lining every clue up before you answer is what these puzzles reward.

That’s it.

Close — follow the rule, don’t add to it.

If every chess player also plays the violin, then anyone who does not play the violin cannot be a chess player. Dev does not play the violin, so Dev cannot play chess. The other options add facts the statements never give.

That’s it.

Close — settle the pets you can be sure of first.

Anya can’t have fur, so she has the fish. Bo takes his pet for walks, so Bo has the dog (the fish is taken, and you don’t walk a cat). That leaves the cat for Cara. Fixing the certain pets first leaves the last one by elimination.

That’s it.

Close — find the missing link in the argument.

The poster jumps from “most popular” to “good choice”. That only works if being popular actually makes something a good choice — the unstated assumption. The other options may be true, but the argument doesn’t depend on them.

That’s it.

Close — look for another cause of the fast time.

Ravi assumes the shoes caused his fast time. If a tailwind pushed him the whole way, that — not the shoes — could explain the best time. Pointing to another likely cause is the strongest way to weaken a “this caused that” claim.

That’s it.

Close — look at how the gaps grow.

Each number is a square: 1×1, 2×2, 3×3, 4×4, 5×5, so the next is 6×6 = 36. You can also see the gaps grow by 2 each time (+3, +5, +7, +9, then +11), and 25 + 11 = 36.
