It is C I got this question on USA test prep
I think it is c.
It's one of those two. Do you a gerund when you see it? Do you know an infinitive?
To determine which description is accurate and true of all three sentences, we need to examine the grammatical structure of each sentence.
1. "We struggled to understand the complicated algebraic expressions."
In this sentence, "struggled" is the main verb, and "to understand the complicated algebraic expressions" is an infinitive phrase acting as the direct object of the verb. It does not take the place of a noun, verb, or function as an adjective.
2. "We could not wait to hear our grades on the final exam."
In this sentence, "wait" is the main verb, and "to hear our grades on the final exam" is an infinitive phrase acting as the direct object of the verb. It also does not take the place of a noun, verb, or function as an adjective.
3. "We failed to demonstrate our knowledge and understanding."
In this sentence, "failed" is the main verb, and "to demonstrate our knowledge and understanding" is an infinitive phrase acting as the direct object of the verb. Just like the previous sentences, it does not take the place of a noun, verb, or function as an adjective.
Based on the analysis, none of the given options accurately describe the grammatical structure of all three sentences. Therefore, none of the options (A, B, C, or D) can be considered accurate and true for these sentences.
