Complete the sentence: These days, in millions of homes around the world, people make cups of tea _________ tea bags.

• A. Use
• B. From
• C. With
• D. Using

Answer: (C)

This sentence tests how we show the means or instrument used to do something. When you say you make something with something else, the second item is the tool or material you use. Here, cups of tea are made with tea bags, so the word with is the natural choice. It keeps the meaning clear: the tea bags are what you use to make the tea. Using or using-tea-bags would work in a slightly different phrasing (make cups of tea using tea bags), but with fits the exact structure of the sentence as written, and from would change the sense to tea being derived from the tea bags rather than made with them.
