For this question, select the option that best explains the information conveyed in the sentence.  The boy accused his friend of putting a spoke in his wheel.

Step 1: Analyze the question The sentence uses the idiom "to put a spoke in someone's wheel." We need the option that best explains what the boy accused his friend of.

Step 2: Explain the concept "To put a spoke in someone's wheel" means to deliberately obstruct, hinder, or frustrate someone's plans or activities. It is figurative, not literal. It has nothing to do with real bicycle wheels.

Step 3: Evaluate the options

• A. Making jest of him: This means making fun of him. It is about mockery, not obstruction. ❌
• B. Spoiling his bicycle wheel: This is a literal reading of the idiom. Idioms are rarely literal. ❌
• C. Destroying his move of getting a new wheel: This is also too literal, since it ties the meaning to an actual wheel. It is awkwardly worded too ("asked his friend of"). ❌
• D. Thwarting the execution of his plan: "Thwarting" means preventing or frustrating, and "plan" matches the idea of what was obstructed. ✅

Step 4: Answer The boy accused his friend of blocking or frustrating his plans.

Tip: When you see an idiom in a JAMB "best explains the sentence" question, eliminate the literal options first. Then pick the one that gives the figurative meaning. Related idioms: "throw a spanner in the works" and "put a stick in one's spokes" carry the same meaning of obstruction.
