Let's solve this worksheet on relative pronouns step by step.

🔹 What are relative pronouns?

Relative pronouns connect a dependent clause to an independent clause. Common relative pronouns include:

- who – refers to people (subject)
- whom – refers to people (object)
- whose – shows possession (people or things)
- which – refers to things, animals, or ideas
- that – refers to people or things (can be subject or object)
- where – refers to places
- when – refers to time

We’ll use the correct one based on:
- The antecedent (the noun being described)
- Whether it’s subject or object
- Whether it shows possession

---

Now, let's go through each sentence and fill in the blank with the appropriate relative pronoun.

---

1. Reynold lost the watch ________ his father had gifted him.

- "watch" is a thing, and the clause "his father had gifted him" describes what happened to the watch.
- We need a relative pronoun that refers to a thing and acts as the object of the verb "gifted".
- Correct: that or which (both work for objects of things).

✔ Answer: that or which

> ✔️ *Reynold lost the watch that his father had gifted him.*

---

2. I met the author, ________ wrote the Harry Potter series.

- "author" is a person; the clause tells us who the author is.
- The relative pronoun is the subject of "wrote".
- Use who.

✔ Answer: who

> ✔️ *I met the author, who wrote the Harry Potter series.*

---

3. Dr. Seuss, ________ is a popular children's books author, is loved by many.

- This is a non-restrictive clause (extra info), so we use who or whom depending on role.
- Here, “is a popular...” has Dr. Seuss as the subject → so the pronoun must be subject form.
- Use who.

✔ Answer: who

> ✔️ *Dr. Seuss, who is a popular children's books author, is loved by many.*

---

4. Please return the book ________ I gave you on Monday.

- "book" is a thing; the clause "I gave you..." says what was done to the book.
- "book" is the direct object of "gave".
- So we need a relative pronoun that refers to a thing and acts as object.
- Use that or which.

✔ Answer: that or which

> ✔️ *Please return the book that I gave you on Monday.*

---

5. This is the juggler ________ we saw at the circus.

- "juggler" is a person; the clause "we saw..." means "we saw the juggler".
- "juggler" is the object of "saw".
- So we need the object form of the relative pronoun for a person.
- Use whom (formal) or who (common in informal speech).

But note: In modern English, who is often used instead of whom even when it's the object.

✔ Answer: who or whom
(But who is more common and acceptable here.)

> ✔️ *This is the juggler who we saw at the circus.*

---

6. Jennifer, ________ mother is a teacher, is my friend.

- "Jennifer" is a person; "mother" belongs to her → we're showing possession.
- So we need whose.

✔ Answer: whose

> ✔️ *Jennifer, whose mother is a teacher, is my friend.*

---

7. The roasted turkey, ________ I made, was loved by all.

- "turkey" is a thing; the clause "I made" says who made it.
- "I made" → "I made the turkey" → turkey is the object.
- So we need a relative pronoun for a thing, acting as object.
- Use that or which.
- But since it's non-restrictive (comma used), we can't use that — only which.

Wait! Actually, that cannot be used in non-restrictive clauses. Only which can.

So: ✔ which

> ✔️ *The roasted turkey, which I made, was loved by all.*

---

8. This is the art gallery ________ displays abstract art.

- "art gallery" is a place; the clause "displays abstract art" says what the gallery does.
- "gallery" is the subject of "displays".
- So we need a relative pronoun that refers to a place and acts as subject.
- Use that or which (both work for things).

✔ Answer: that or which

> ✔️ *This is the art gallery that displays abstract art.*

---

9. Mrs. Simpson, ________ is a dentist, will be here soon.

- "Mrs. Simpson" is a person; the clause adds extra info about her profession.
- "is a dentist" → she is the subject.
- So use who.

✔ Answer: who

> ✔️ *Mrs. Simpson, who is a dentist, will be here soon.*

---

10. This is Aaron, ________ the scientist I had met last month.

- This is tricky.
- "Aaron" is a person.
- The clause "the scientist I had met last month" is describing Aaron.
- So we need a relative pronoun that links Aaron to the description.
- We’re saying: "Aaron is the scientist I met."
- So the structure is: This is Aaron, who is the scientist I had met last month.

But wait — the sentence is:
"This is Aaron, ________ the scientist I had met last month."

That seems incomplete unless we use who or whom.

But actually, the intended meaning is:
"Aaron is the scientist I had met last month."

So we need a relative pronoun to link Aaron to the identity.

Best choice: who (subject)

✔ Answer: who

> ✔️ *This is Aaron, who is the scientist I had met last month.*

But wait — the original sentence doesn’t have "is". Let's check:

> "This is Aaron, ________ the scientist I had met last month."

That’s awkward. It should probably be:
"This is Aaron, who is the scientist I had met last month."

But if the sentence is literally as written, then it might be missing "is", but we assume it's implied.

Alternatively, some might write:
"This is Aaron, the scientist whom I had met last month." → but then "whom" is the object.

Wait — "I had met him" → so whom is correct.

But the sentence structure is:

> "This is Aaron, ________ the scientist I had met last month."

This implies:
"This is Aaron, [relative pronoun] the scientist I had met last month."

That would mean:
"This is Aaron, who is the scientist I had met last month."

But again, "is" is missing.

So likely, the intended answer is who.

✔ Answer: who

> ✔️ *This is Aaron, who is the scientist I had met last month.*

💡 Tips:

- Use who for people (subject), whom for people (object), whose for possession.
- Use which for things (especially in non-restrictive clauses), that for things or people (restrictive).
- Where for places, when for times.
- Non-restrictive clauses use commas and usually who/which, not that.
