Question

should there be a comma before the highlighted word?
drax will go either hiking or sailing on saturday.
add a comma
dont add a comma

Explanation:

The sentence uses the correlative conjunction pair "either...or" to connect two parallel nouns ("hiking" and "sailing"). A comma is not used between the two elements linked by "either...or" when they are parallel, equal parts of a phrase.

Answer:

Don't Add a Comma
