At the motel, we used the exercise room and swam in the outdoor pool.

In the sentence above, the underlined part should be
written:

Group of answer choices

A)swammed

B)swum

C)swimmed

D)swam

The answer would be C) swimmed.

Explanation:

If you put each answer into the sentence, you can see if it does or doesn't make sense. Ex:

Lets try A first:

At the motel, we used the exercise room and swammed in  the outdoor pool.

Although saying "swammed" might be fun, this does not make sense, therefore the answer cannot be A.

Lets try B next!

At the motel, we used the exercise room and swum in  the outdoor pool.

Again, this might be fun to say and all, but this does not make sense, so we should try C next.

At the motel, we used the exercise room and swimmed in  the outdoor pool.

This one makes sense and works! We should still try the last answer, D, though (you never know!)

At the motel, we used the exercise room and swam in  the outdoor pool.

At first glance, this may seem correct, but if you say this out loud, it doesn't make sense. The answer must be C) swimmed.

Hope this helped! :)
