Read the paragraphs about three trips. Choose the correct answer (A, B, or C).

LAST WEEKEND

A. Last Sunday, I visited my grandparents by train. It took about an hour. Traveling by train is a lot quicker than going by bus. The bus isn't as comfortable as the train. When I got to the train station, I took a taxi to my grandparents' house.

B. Last weekend, I went to the shopping mall in Rockville. It's a lot cheaper than shopping in my hometown. I went by bus because the train was full. It wasn't very comfortable. The ticket wasn't as expensive as the train so I had more money to spend on clothes!

C. My dad took me to a bowling alley last weekend. We usually go there by subway because it's quicker than buses. It's also reliable and you never have to wait for long. But Dad decided we should go by taxi. It wasn't as cheap as the bus, but it was so comfortable. We had a really fun day together!

Whose trip was cheap?
