Question

1. if you are observant, you ______ closely at your surroundings.

a) care \tb) look
c) move \td) talk

Explanation:

To solve this, we analyze the meaning of "observant" (paying attention to details) and the verb - object collocations:

• Option a: "care" collocates with "about" (e.g., care about), not "at", so it's incorrect.
• Option b: "look at" means to direct one's gaze towards, which fits with being observant (looking closely at surroundings).
• Option c: "move at" is an incorrect collocation; "move" is about changing position, not observing.
• Option d: "talk at" means to speak to someone without listening, which has nothing to do with observing.

Answer:

b) look
