Kofi is too … ; he wants to know about everybody's business

Step 1: Analyze the question The sentence is "Kofi is too ....... ; he wants to know about everybody's business." The part after the semicolon explains the missing word. So we need an adjective describing someone who is overly eager to learn about other people's affairs.

Step 2: Explain the concept This is a vocabulary-in-context question. Use the clue after the semicolon ("wants to know about everybody's business") to find the word with the matching meaning.

Step 3: Test each option

• A. inquisitive: means overly curious, keen to find out things, often about others. It fits the clue exactly.
• B. friendly: means warm and sociable. Being friendly does not mean wanting to know everyone's business, and "too friendly" does not fit the explanation.
• C. concerned: means worried or caring. It does not carry the idea of prying into others' affairs.
• D. busy: means occupied. It is almost the opposite, since someone busy with their own tasks would not be poking into everyone else's.

Step 4: Answer The correct option is A. inquisitive.

Exam tip: In "too ....... ; ..." sentences, the clause after the semicolon or colon usually defines the missing word. Match its meaning to the options. Also remember related words: inquisitive (nosy or curious), nosy (informal), and meddlesome (interfering).
