In each of this question choose the option opposite in meaning to the word or phrase underlined The girl took a cursory glance at the letter and hid it

Analyze the question: We need the word opposite in meaning to "cursory" in the sentence "The girl took a cursory glance at the letter and hid it."

Explain the concept: "Cursory" means hasty, quick, and superficial, done without attention to detail. Its synonyms include brief, hurried, passing, and perfunctory. Its antonyms include thorough, careful, detailed, and in-depth.

Solution: Let's test each option.

• A. Concise means brief and to the point. This is close to "cursory" in the sense of shortness, so it is not the opposite.
• B. Brief means short. This is a synonym of "cursory", so it is not the opposite.
• C. Lasting means continuing for a long time. Compared with a quick, fleeting glance, a lasting glance is prolonged. This is the one that works as an opposite.
• D. Sententious means full of moralizing or pithy sayings. It does not relate to glancing and is not an opposite.

None of the options is the perfect antonym (a word like "thorough" would be ideal), but the question asks for the option opposite in meaning. Of the four, only "lasting" points in the opposite direction from "brief and fleeting", while A and B are clearly similar in meaning.

Answer: C. Lasting

Tip: In "opposite in meaning" questions, first eliminate the options that are synonyms of the underlined word. Here, "concise" and "brief" are both similar to "cursory", so they can be removed right away. Then choose the remaining option that pulls in the opposite direction. Also remember: cursory = quick and superficial, so its opposites are thorough, detailed, and prolonged.
