Final answer:
The sentence 'Will you be at the party tonight?' contains an obligatory context for the uncontractible copula BE.
Step-by-step explanation:
The sentence 'Will you be at the party tonight?' contains an obligatory context for the uncontractible copula BE.
An obligatory context for the uncontractible copula BE is when a form of be (am, is, are, was, were) serves as the main verb of a sentence, an adverbial of time or place, an adjectival, or a noun phrase follows it.
In this sentence, 'Will you' is the subject, 'be' is the uncontractible copula BE verb, and 'at the party tonight' is the adverbial of time.
Therefore, the statement is True.
The sentence 'Will you be at the party tonight?' does not contain an obligatory context for the uncontractible copula BE (am, are, is, was, were).
The structure of the sentence is a question that anticipates a response involving a be verb and an adverbial of time or place, but it does not itself contain the copula BE in an uncontracted form. Therefore, the correct answer to the student's question is B. False.
