Choose all the phrases.

Let's analyze each option:

• brightly colored watermelon: This is a noun phrase. It describes a watermelon and does not have a subject performing an action.
• today: This is a single word (an adverb), not a group of words, so it is not typically considered a phrase in this context.
• eating all the soup: This is a participial phrase. "eating" is a verb form, but there is no subject within this group of words performing the action.
• he watched: This is a clause because it contains both a subject ("he") and a finite verb ("watched").

Therefore, the phrases are "brightly colored watermelon" and "eating all the soup".

The phrases are:

• brightly colored watermelon
• eating all the soup
