Last year / many people / died from cholera epidemic.

Answer: Option C

Question: Last year / many people / died from cholera epidemic.

This sentence tests your understanding of subject-verb agreement and the correct use of prepositions.

Let's break down each part:

Option A: Last year - This is an adverbial phrase indicating time. It's grammatically correct.

Option B: many people - This is the subject of the sentence. "Many" is a quantifier modifying the plural noun "people". This is grammatically correct.

Option C: died from cholera epidemic - This is the verb phrase. The verb "died" agrees with the plural subject "many people". However, the prepositional phrase "from cholera epidemic" might be slightly problematic. While understandable, it's more natural and precise to say "died *in* a cholera epidemic" or "died *of* cholera". "Died from" implies a more direct cause (e.g., "He died from a gunshot wound"), whereas a cholera epidemic is a context, not a direct cause in the same way.

Option D: No Error - Considering the slightly awkward prepositional phrase, this is unlikely to be correct.

Therefore, the answer is Option C because the preposition "from" is not the most suitable choice to describe death caused by an epidemic. Using "in" or "of" would make the sentence more accurate and natural.
