Final answer:
The sentence 'We were wondering if you had any seats left' is false for containing an obligatory context for the uncontractible copula BE; 'were' acts as a helper verb in a verb phrase.
Step-by-step explanation:
The sentence "We were wondering if you had any seats left" does not contain an obligatory context for the uncontractible copula BE (am, are, is, was, were), so the statement is False.
An obligatory context would require that the main verb be a form of BE followed by a specific pattern such as an adverbial of time or place, an adjectival, or a noun phrase. In the sentence provided, 'were wondering' acts as a past continuous verb phrase and 'were' is not used as a main verb but as a helper verb.
The sentence provided, 'We were wondering if you had any seats left,' contains an obligatory context for the uncontractible copula BE (am, are, is, was, were). In this case, 'were' is the uncontractible copula, and it is necessary to express the past tense of the verb 'to be' in the sentence.
