Fron the options lettered A-D, choose the word(s) that is opposite in meaning to the word(s) underlined and…

Analyze the question: The sentence says Bayo is careless in his ways, and we need a word that is the opposite of "careless" to describe Tayo. The word must also fit the sentence naturally.

Explain the concept: This is an antonym question. The contrast word "while" signals that Tayo is the opposite of Bayo, so we need a word meaning the reverse of careless.

• Careless means not paying attention to detail, and being negligent or sloppy.
• Its opposite is careful, thorough, painstaking or meticulous.

Step-by-step solution:

• A. lovable means easy to love. It has nothing to do with carefulness, so it is wrong.
• B. meticulous means very careful and precise, paying great attention to detail. This is a direct opposite of careless, so it fits.
• C. difficult means hard to deal with. It is not related to carelessness, so it is wrong.
• D. reserved means quiet or slow to show feelings. It is not an antonym of careless, so it is wrong.

Answer: Option B. meticulous. The sentence reads: "Bayo is careless in his ways while Tayo is meticulous."

Exam tip: In antonym-in-context questions, look for contrast signals such as while, but, whereas, however. They tell you the missing word must be the opposite of the underlined word. Also learn a few "careful" synonyms that often appear as answers: meticulous, scrupulous, painstaking, diligent.
