Final answer:
The sentence 'This hard work' does not include an obligatory context for the uncontactable copula BE as it lacks a subject followed by the copula and additional information such as an adverbial of time or place, an adjectival, or a noun phrase.
Step-by-step explanation:
The sentence "This hard work" does not contain an obligatory context for the uncontactable copula BE (am, are, is, was, were). For a sentence to contain an obligatory context of the copula BE, it typically needs a subject followed by a form of the copula and then some additional information like an adverbial of time or place, an adjectival, or a noun phrase.
For example, a complete sentence with the copula BE might look like 'The children are at the park.' Here, 'The children' is the subject, 'are' is the copula, and 'at the park' is an adverbial of place, following one of the patterns mentioned. The given phrase "This hard work" lacks these additional elements, making it an incomplete sentence and thereby false in terms of having an obligatory context for the copula BE.
