Select the option that best explain the information conveyed in the sentence Advising Olu to break his bad habit is like knocking your head against a brick wall

Step 1: Analyze the question The sentence uses a simile: "Advising Olu to break his bad habit is like knocking your head against a brick wall." We need the option that best captures the meaning.

Step 2: Explain the concept This is a figurative expression (an idiom related to "banging your head against a brick wall"). It describes doing something that is frustrating and useless, because the person or situation will not change. No matter how hard you try, you get no result, and you only hurt yourself in the process.

Step 3: Work through the options

• A. It is making a fool of you. The sentence is not about embarrassment or looking foolish. It is about futility.
• B. It is trying the impossible. Advice to Olu will not work, just as knocking your head on a brick wall will not break the wall. The effort is pointless, as if the task were impossible. This fits.
• C. It is making him your enemy. Nothing in the sentence suggests this.
• D. It is asking him to beat you. This takes the "knocking" too literally and ignores the idiom.

Step 4: Answer The correct option is **B. It is trying the impossible.

Exam tip: For "best explains" questions on similes and idioms, ask: "What is the overall message?" Ignore the literal image. "Brick wall" in an idiom nearly always points to futility, meaning a task that cannot succeed. Related expressions are "flogging a dead horse" and "water off a duck's back."
