The old fire station has obviously become derelict.

Analyze the question: The word "derelict" is underlined, and you need the option closest in meaning to it.

Explain the concept: "Derelict" describes something abandoned, neglected, and in a state of disrepair, such as an old building nobody takes care of. It is often used for property that has fallen into ruin.

Check each option:

• A. moribund: Literally means "at the point of death", and it is used for things in a state of decline, stagnation, or near-collapse. This is the closest in meaning, since a derelict building is run-down and decaying, with no life or activity left in it.
• B. glamorous: Attractive and exciting. This is the opposite of derelict.
• C. enlivened: Made lively or cheerful. This is also the opposite.
• D. titivated: Spruced up or made smart. This is again the opposite.

Answer: Options B, C and D all describe improvement, while derelict describes decline. Only A, moribund, points in the same direction (decay and lack of vitality). Strictly speaking, "moribund" is not a perfect synonym, because it usually describes things that are dying, while "derelict" means abandoned and dilapidated.

Tip: When no option is a perfect synonym, first eliminate the opposites. Here three options are positive and one is negative, so the negative one is the answer. Also remember "derelict" with "dereliction of duty", which means neglect or abandonment.
