For this question, choose the option opposite in meaning to the word or phrase in italics It is Iudicrous to suggest that she was a government agent

Analyze the question: You need the word that is opposite in meaning to ludicrous (the question shows it as "Iudicrous", a typing slip for "ludicrous").

Explain the concept: Ludicrous means absurd, ridiculous, or laughable because it is so unreasonable. Its antonym is something reasonable, logical, or wise.

Step-by-step solution:

• A. odd – Odd means strange or unusual. This is close to ludicrous, so it is not the opposite.
• B. exciting – This means thrilling. It has no real link to ludicrous in either direction.
• C. farcical – Farcical means absurd, like a farce. It is a synonym of ludicrous, so it is not the opposite.
• D. sensible – Sensible means reasonable and practical. This is the opposite of absurd or ridiculous.

Put the options into the sentence: "It is sensible to suggest that she was a government agent" gives the opposite idea to "It is ludicrous to suggest...", because one calls the suggestion reasonable and the other calls it absurd.

Tip: In antonym questions, first spot the options that are synonyms (here, farcical and odd) and eliminate them. The examiners often include synonyms as traps. Then choose the option that clearly carries the reverse meaning.
