Olu gave his brother a bumpy ride.

Step 1: Analyze the question The sentence "Olu gave his brother a bumpy ride" is being tested for its figurative (idiomatic) meaning. The question asks which option best explains the information it conveys.

Step 2: Explain the concept "To give someone a bumpy ride" (also "a rough ride" or "a hard time") is an idiom. It means to make a situation difficult, uncomfortable, or stressful for someone, usually by questioning, criticising, or opposing them. It is not about an actual vehicle or road.

Step 3: Evaluate the options

• A. Olu's brother rode on Olu's back to success. This suggests the brother benefited from Olu's help. It is the opposite of troubling him, so it is wrong.
• B. Olu took his brother on a bumpy road. This is the literal reading. The idiom is figurative, so it is a trap option.
• C. Olu gave his brother a difficult time. This matches the idiom's meaning exactly: he made things hard for his brother.
• D. Olu gave his brother a ride on his car. This is also literal, and it says nothing about difficulty.

Step 4: Answer The correct option is C.

Tip: When a JAMB "best explains the sentence" question includes both a literal option and a figurative one, check whether the phrase is an idiom. Phrases like "bumpy ride", "rough time" and "hard time" almost always point to difficulty, not physical travel.
