I have always found that it is helpful to have a few wise and trusted people to … you can turn for information…

Analyze the question

The sentence is: "I have always found that it is helpful to have a few wise and trusted people to __ you can turn for information and advice."

We need the correct relative pronoun after the preposition "to".

Explain the concept

When a relative pronoun comes directly after a preposition (to, for, with, by, from), it must be in the objective case. That means we use whom, not "who". We also cannot use "that" or "whose" immediately after a preposition in this structure.

• who = subject (e.g., "people who help you")
• whom = object (e.g., "people to whom you turn")
• whose = possession (e.g., "people whose advice you value")
• that = cannot follow a preposition directly

Step-by-step solution

1. The clause is: "you can turn to __ for information and advice."
2. The verb phrase "turn to" needs an object. The people are the ones being turned to.
3. The gap comes right after the preposition "to", so we need the objective form: whom.
4. Check by rearranging: "You can turn to them." Since "them" is the objective form, the relative pronoun is "whom".
5. Eliminate the others: • who: subjective, so it is wrong after a preposition. • whose: shows possession, which makes no sense here. • that: cannot be used directly after a preposition.

Completed sentence: "I have always found that it is helpful to have a few wise and trusted people to whom you can turn for information and advice."

Answer: A. whom

Exam tip

Use the "him/them" test: if you can replace the word with him or them, use whom. If you can replace it with he or they, use who. Also remember that preposition + whom is a very common JAMB pattern (to whom, with whom, for whom, by whom).
