TOEIC Link Part 5: choosing the right relative pronoun (who, which, that, whose, where)

Part 5 relative-pronoun blanks are decided by two questions: what does the word refer to, and what job does it do inside its own clause. This guide gives you a two-step check that separates who from which, whose from who, and where from which, so you stop guessing between forms that all look grammatical.

TOEIC Link Part 5: choosing the right relative pronoun (who, which, that, whose, where)

A relative-pronoun blank in Part 5 looks like a vocabulary question but is really a structure question. The choices — who, which, that, whose, where — are all relative pronouns, so no single one is "more advanced" than another. Exactly one fits the grammar of the sentence, and the test rewards you for reading the clause, not for recognizing the words. The good news is that two quick questions settle almost every one of these blanks. If you already handle pronoun–antecedent agreement for ordinary pronouns, this is the relative-clause version of the same skill: match the pronoun to what it points at, then to the job it does.

The two questions that decide every relative pronoun

Ask them in order:

  1. What does the pronoun refer to — a person, a thing, or a place? That splits the field: who for people, which for things, where for places, that for either people or things, whose for possession by either.
  2. What job does the pronoun do inside its own clause — subject, object, possessor, or location? That decides between the forms that survived question 1.

Most wrong answers fail question 1 (they use which for a person or who for a thing). The genuinely tricky items fail question 2 — usually the difference between who and whose.

Person vs. thing vs. place: question one

The manager __ approved the budget will present it tomorrow. (A) which (B) who (C) where (D) whose

The pronoun refers to the manager — a person — and it is the subject of approved. That points straight to (B) who. Which is for things, where is for places, and whose would need a noun right after it (see below). Question 1 alone eliminates three options here.

The reverse case:

The software __ we installed last week has already crashed twice. (A) who (B) whose (C) which (D) when

Software is a thing, so who is out. Which (or that) is correct: (C). Notice which is the object of installed — English uses the same form which for subject and object, so question 2 does not change the answer for things. That is why person-vs-thing errors are the most common trap the test sets.

Whose vs. who: question two

Whose shows possession, and the clean signal is that a noun follows it directly:

We hired a consultant __ recommendations saved the company millions. (A) who (B) whose (C) which (D) that

The blank is followed by recommendations — a noun the consultant owns. Only whose can sit before a possessed noun: (B). Swap in who and the sentence has no possessor: who recommendations is ungrammatical. Whenever a relative-pronoun blank is immediately followed by a bare noun, check whose first.

Where vs. which: the location trap

The warehouse __ the goods are stored is being renovated. (A) which (B) where (C) that (D) who

Both where and which can attach to a place, but they do different jobs. Use where when the clause already has a complete sentence that needs no object — the goods are stored is complete, and where just adds "in that place." Use which/that only when the clause is missing a subject or object. Here the clause is complete, so (B) where fits. A useful rewrite test: if you can say "in which" instead of the blank (the warehouse in which the goods are stored), then where is right.

That vs. who/which: when the test allows both

In defining clauses, that can replace who (people) or which (things), so a well-written Part 5 item will not offer both that and the specific pronoun as if both were correct — it will make only one grammatical. Watch for two cases where that is wrong: after a comma (non-defining clauses take who/which, never that) and after a preposition (the project on that we worked is impossible; it must be on which). If you see a comma or a preposition right before the blank, cross that off immediately. This ties back to reading the clause structure, the same habit that drives preposition vs. conjunction vs. adverb slotting.

Putting it together

Run the two questions on every relative-pronoun blank:

  1. Refers to a person → who/whose/that. A thing → which/that. A place with a complete clause → where.
  2. Followed by a noun → whose. After a comma or preposition → not that. Clause missing a subject/object → who/which/that, not where.

Two questions, five pronouns, and almost no guessing left. The blank stops being a vocabulary lottery and becomes a short structural check you can finish in a few seconds.
