Why-questions: the reason the passage gives
A why-question, or a stem ending in 'because', asks for the reason the passage gives. Find the line that carries the reason, then pick the option that says it in other words.
Why this matters
Why-questions are among the most common in CDS reading. The reason is in the passage, but the right option almost never uses the passage's own words. The wrong options are often other true facts from the same passage, a common-sense reason the writer never gives, or an excuse a character makes.
Concept 1 of 3: Find the because-line, then match its paraphrase
Definition
The terms:
- Reason signals: because, since, as, so, therefore, due to, owing to, for fear of, as a result of, chiefly because, which is why.
- Paraphrase: the same meaning in different words.
The method:
- Find the line about the event in the stem.
- Look on both sides of it for a reason signal. The reason can come before the event ('Fearing rain, they left early') or after it ('They left early because they feared rain').
- Say the reason in your own words, in a few words.
- Pick the option that says the same thing. Expect new words: afraid of being laughed at becomes fear of ridicule.
- Strike options that give a reason the passage does not, even a sensible one.

Concept 2 of 3: The reason one step from the line
Definition
The method:
- Find the event in the stem.
- Look nearby for a condition (if, unless, only if, when), a rule the passage states, or what happens just before the event.
- Turn the condition into a reason: 'Unless seeds are kept dry, they rot' plus 'the store-room leaked' gives: they rotted because they were not kept dry.
- Check the step is short: you can point at the line and say 'that is why'.
- Strike reasons that need a second step or a fact you add yourself.

Concept 3 of 3: The real reason, not a true side-fact
Definition
The method:
- Separate what a person says from what the writer shows. A character's stated reason can be a cover.
- Read to the end of the passage. The real reason is often revealed late.
- If the reason has two halves (A, and at the same time B), the option must carry both.
- A true fact from the passage is not the answer unless it explains the event in the stem.
- Check the option against the writer's own view, not a view the writer sets aside.
