Choose the option nearest in meaning to the underlined word(s).
Their new house was roofed with corrugated sheets.
Answer Details
The word "corrugated" refers to a type of material that is shaped with parallel ridges and grooves. Therefore, the option nearest in meaning to the underlined word is "folded", as it also describes a material that has been bent or shaped into ridges and grooves. The other options ("iron", "aluminium", "corrupted") do not have the same meaning as "corrugated".
