1. Why "pose to being" is wrong:
In English, the verb "pose" (when meaning to present a problem or danger) is followed by a specific structure. The construction "pose to being" is grammatically incorrect because the preposition "to" here should be followed by the base form of the verb (infinitive) or a noun, not the "ing" (gerund) form in this specific context.
2. Why "posed to be" is correct:
Tense: Since the sentence refers to the construction of a temple (likely a historical reference or a completed task by "masons"), the Past Tense ("posed") is the most logical fit.
Structure: "Posed to be" (meaning "turned out to be" or "presented itself as") is a standard way to describe a challenge.
Collocation: We often say something "posed a challenge" or "posed a threat." When adding a verb, "posed to be" functions correctly to identify the nature of the hurdle.
