Their new house was roofed with corrugated sheets?

Analyze the question: The underlined word is "corrugated" in "roofed with corrugated sheets." We need the option closest in meaning.

Explain the concept: "Corrugated" means shaped into parallel ridges and grooves, like folds or waves. This shape makes thin metal sheets stronger and stiffer. In Nigeria, we commonly see "zinc" or "iron sheets" with this wavy pattern.

Work through the options:

• A. folded: Corrugated material is bent into repeated folds or ridges, so this is the closest in meaning to the shape described.
• B. iron: This names a possible material, not the meaning of the word. Corrugated sheets can be iron, but "corrugated" does not mean "iron."
• C. aluminium: Again a material. Corrugated sheets can be aluminium, but the word does not mean that.
• D. corrupted: This is a distractor. It looks and sounds similar to "corrugated" but means "spoiled" or "dishonest."

Identify the answer: The best match is A. folded.

I should be honest that this is a slightly loose question. "Corrugated" really means "ridged" or "wrinkled," and "folded" is only an approximate synonym. Still, it is the only option that describes the shape rather than a material or an unrelated word.

Exam tip: In "nearest in meaning" questions, watch for look-alike words (corrugated and corrupted) and for options that name a thing rather than give a meaning. Ask yourself, "Does this option define the word, or just go with it?" Here, only "folded" defines it.
