Step 1: Analyze the question The sentence uses the idiom "at the crossroads." You are asked to choose the meaning that best fits it.

Step 2: Explain the concept A crossroads is a place where roads meet and you must choose which way to go. As an idiom, "at a crossroads in one's life" means being at a critical turning point where an important decision must be made. That decision will affect the future direction of your life.

Step 3: Test each option

• A. make a very important decision: This matches the idiom exactly, since a crossroads means choosing between paths.
• B. retrace his steps: This means going back the way you came. The idiom is about choosing a way forward, not going back.
• C. make peace with everyone: This is about reconciliation and has nothing to do with the idiom.
• D. take matters seriously: A crossroads moment is serious, but the idiom specifically means making a decision, not just being serious.

Tip: For idiom questions, picture the literal image. A crossroads means several paths and one choice, so the meaning is "a decision point." Linking idioms to a mental picture makes them easier to remember in the exam hall.
