(2) She will not go to the very highest peak.

*Those are the four choices. I don't know what a helping verb does in a sentence...so...HELP PLEASE!

So basically it's saying which sentence doesn't have one of those helping verbs?

Yes.

Sure, I can help you understand what a helping verb is in a sentence.

A helping verb (also known as an auxiliary verb) is a verb that helps to express the tense, mood, or voice of the main verb in a sentence. It works together with the main verb to make a complete thought.

Let's analyze the four sentences you provided and identify the helping verbs:

(1) Erica is climbing the steepest trail.
In this sentence, the helping verb is "is," which is used to express the present progressive tense.

(2) She will not go to the very highest peak.
Here, the helping verb is "will," which is used to express future tense.

(3) She wants a photograph of the valley below.
In this sentence, there is no helping verb. The word "wants" is the main verb, which expresses the present tense.

(4) Has she ever made the climb before?
The helping verb in this sentence is "has," which is used to express present perfect tense.

Now, looking at the four options you provided, we can see that sentences (1), (2), and (4) contain helping verbs.

Therefore, the sentence that does not contain a helping verb is option (3):
"She wants a photograph of the valley below."
