A. Eduardo looked in the basement, but the puppy wasn’t there.
B. Sakkom hung wind chimes because she loves the sound.
C. Roger has never performed a solo in his life.
D. The leader of the troop took the scouts to the lake.
To determine which of the given sentences contains a helping verb, it is important to first understand what a helping verb is. A helping verb, also known as an auxiliary verb, is a verb that helps or adds meaning to the main verb in a sentence. Common helping verbs include "is," "am," "are," "was," "were," "be," "being," "been," "have," "has," "had," "do," "does," and "did."
Now, let's examine the given sentences:
A. "Eduardo looked in the basement, but the puppy wasn’t there."
In this sentence, the helping verb is "wasn't," which is a contraction of "was not." It helps to convey the negative past tense of the main verb "be" (which is "was").
B. "Sakkom hung wind chimes because she loves the sound."
This sentence does not contain a helping verb. It has a main verb ("hung") but no auxiliary verb to assist it.
C. "Roger has never performed a solo in his life."
The helping verb in this sentence is "has." It is used to form the present perfect tense of the main verb "perform."
D. "The leader of the troop took the scouts to the lake."
This sentence does not have a helping verb. The main verb "took" is not accompanied by an auxiliary verb.
Therefore, based on the analysis of the given sentences, the sentence that contains a helping verb is sentence C: "Roger has never performed a solo in his life."
