In the following sentence what is the better choice and why.....

I'll bet it feels good or well to run around those bases.

It feels good . . .

Since "good" is an adjective and describes "it," it's the correct choice.

Although "well" can be used as an adjective to describe a person's health, "well" is also an adverb.

Examples of "well" used as an adverb:
The child draws well for his age.
Since the freshman plays so well, the coach promoted him to the varsity team.

To determine the better choice between "good" and "well" in the given sentence, we need to understand the difference between these two words.

"Good" is an adjective used to describe nouns. It is used to express and evaluate the quality or condition of something. For example, "the pizza tastes good."

"Well," on the other hand, is an adverb used to describe verbs, adjectives, or other adverbs. It is used to express how an action is performed or the condition of someone or something. For example, "he runs well."

In the sentence you provided, the word "feels" is a linking verb connecting the subject "it" with the adjective "good" or the adverb "well." Since "feels" refers to a state or condition of something, it requires an adjective to complete the predicate. Therefore, the correct choice in this case would be "good."

The sentence should be written as: "I'll bet it feels good to run around those bases."

To determine the correct word choice, it is always helpful to identify the type of word (adjective or adverb) needed based on the function it performs in the sentence and the word it modifies.
