Let us know what you come up with.

There are two reasons why I like baseball. It is fun and good exercise.

How does this look?

To revise the sentence and remove all fragments, you need to combine the fragmented phrases into complete sentences. Here's the revised version:

"There are two reasons why I like baseball: it is fun, and it provides good exercise."

Explanation:
To revise the sentence, you need to identify the fragments and combine them into complete sentences. In this case, the fragments are "I like baseball" and "It is fun."

To create a complete sentence, you need a subject and a predicate. The subject is "I," indicating the person who likes baseball. The predicate consists of the verb ("like") and the rest of the sentence. So, you can combine the fragments "I like baseball" and "It is fun" into a single complete sentence: "I like baseball because it is fun."

Additionally, you mentioned "And for the good exercise." To make this a complete sentence, you can rephrase it as "It provides good exercise."

Combining these revised sentences gives us: "There are two reasons why I like baseball: it is fun, and it provides good exercise."
