Difficulty: Easy
Correct Answer: Close
Explanation:
Introduction / Context:Action analogies map an object to a common action done to it. A book is opened; a door is commonly opened or closed. Since “open” is already in the prompt, the complementary action “close” forms a balanced, conventional pair.
Given Data / Assumptions:
Concept / Approach:Choose the canonical action forming a familiar opposite pair to “open”: “close.”
Step-by-Step Solution:
1) Book → open (typical action).2) Door → close (balances the pair).3) Evaluate lexical fit and part-of-speech correctness.Verification / Alternative check:Everyday usage pairs “open/close” for doors; “shut” is also acceptable but “close” keeps verbal symmetry.
Why Other Options Are Wrong:
House/Wood: nouns, not actions.Shut: near-synonym but less standard register in such pairs.Lock: specific action after closing; not the basic counterpart to “open.”Common Pitfalls:Picking nouns or over-specific actions (lock) rather than the direct pair.
Final Answer:Close
