Question

In which one of the following sentences is but used as a preposition?

A. I would like to return to Italy, but I have no money.
B. I wanted to leave, but I was embarrassed to do so.
C. The lake is pretty, but it's too cold for swimming.
D. We discovered that Candy will do anything but work.

Answer 1

l would say the answer is C

Answer 2

The correct answer is D. We discovered that Candy will do anything but work.
In all other options, the word but is used as a conjunction, meaning that it connects two or more parts of a sentence. However, in D, the word but is used with the meaning of 'except for,' which is a preposition, thus but is a preposition too in sentence D.
