Final answer:
The sentence 'Are you going to the barbecue?' contains an obligatory context for the uncontractible copula BE (am, are, is, was, were). Therefore, the statement is True.
Step-by-step explanation:
The sentence 'Are you going to the barbecue?' contains an obligatory context for the uncontractible copula BE (am, are, is, was, were). In this sentence, the subject 'you' is followed by the uncontracted form of the verb 'are' (from 'are you') which is 'are'.
This sentence pattern is an example of the first sentence pattern that occurs with the be verb: (subject) + (be verb) + (adverbial of time or place). In this case, the subject 'you' is followed by the be verb 'are' and the adverbial 'going to the barbecue'.
Therefore, the statement is True.
The sentence "Are you going to the barbecue?" contains an example of the uncontractible copula BE in the form of "Are". In this sentence pattern, the BE verb is serving as the main verb and is followed by a noun phrase ("the barbecue").
As such, the correct answer to whether the sentence contains an obligatory context for the uncontractible copula BE (am, are, is, was, were) is True.
