This question tests subject-verb agreement with correlative conjunctions like "neither...nor". The rule is that the verb should agree with the subject closer to it.

Let's break down the original sentence:

Subject: "neither the house nor the factory"

Verb: "were"

The two subjects joined by "nor" are "the house" (singular) and "the factory" (singular). The subject closer to the verb is "the factory", which is singular. Therefore, the verb must also be singular to agree with it.

The original verb "were" is plural, which is incorrect. It should be changed to the singular form "was".

Corrected Sentence: "In the end, he found out that neither the house nor the factory was bequeathed to him in his uncle's will."

When subjects are joined by correlative conjunctions like "neither...nor", "either...or", "not only...but also", the verb agrees with the subject that is nearest to it. This is sometimes called the "Proximity Rule".

• Example 1 (Singular closer): Neither the players nor the coach is happy. (Verb agrees with "coach")
• Example 2 (Plural closer): Neither the coach nor the players are happy. (Verb agrees with "players")

Rule: For compound subjects joined by "or", "nor", "either...or", "neither...nor", "not only...but also", the verb agrees in number and person with the part of the subject that is nearer to the verb.
