_____ of the reasons I came to the UK was to learn English.

• A. One
• B. Many
• C. Several
• D. Some

Answer: (A)

The main idea tested here is matching the determiner to the verb when talking about a single item among several. Saying “One of the reasons I came to the UK …” refers to a single reason, even though there are multiple reasons overall. Because the head of that noun phrase is singular (one), the verb stays singular: “was.” The rest of the sentence then explains that the purpose of that reason was to learn English. Using any of the other options would change the meaning or require a different verb form. “Many,” “Several,” or “Some” would normally go with a plural verb (were) in this structure, or shift the emphasis to more than one reason. So the word that fits with the singular verb and the intended meaning is One.
