Interrogative Pronouns worksheet for grammar practice.

Let’s go through each sentence one by one. We need to pick the right interrogative pronoun — who, whom, what, whose, or which — to complete each question.

Remember:
- “Who” is for people (subject of the verb).
- “Whom” is for people (object of the verb or preposition) — but often replaced with “who” in casual speech.
- “What” is for things or ideas.
- “Whose” shows possession (like “belonging to whom?”).
- “Which” is used when choosing from a limited set (often with “one,” “of these,” etc.).

Now let’s solve each:

1. ___ one of the books is your favorite?
→ We’re picking from specific books → use which

2. To ___ should I address the letter?
→ After “to”, we need object form → whom (but note: already filled as “To” — so blank is after “To”) → actually, the blank is before “should”, and “To” is given — so it’s “To [whom] should I...” → answer: whom

Wait — looking again: #2 says “To ___ should I address the letter?” — that means the blank is the object of “to”. So yes, whom

But wait — in modern usage, many say “who” here too. But since this is grammar practice, we’ll use correct formal grammar: whom

3. ___ shoes are sitting outside the front door?
→ Asking about ownership → whose

4. ___ would you like to get tomorrow?
→ Asking about a thing → what

5. ___ house should we go to on Saturday to watch the game?
→ Choosing among houses → which

6. To ___ was the package sent?
→ Again, object of “to” → whom

7. ___ is the new student in the band?
→ Asking about a person (subject) → who

8. ___ is the title of the poem that you liked?
→ Asking about a thing (title) → what

9. ___ is going to be the guest speaker for the assembly?
→ Person doing the action → who

10. ___ homework was turned in without a name written on it?
→ Possession → whose

11. ___ is your dog’s name?
→ Thing (name) → what

12. ___ car is yours?
→ Possession → whose

13. ___ birthday is in the month of December?
→ Possession → whose

14. To ___ was the angry phone call made?
→ Object of “to” → whom

15. ___ is in the tropical punch in the punch bowl?
→ Asking about contents → what

16. ___ is the new principal of the elementary school?
→ Person → who

17. ___ one of the sandwiches is made with ham?
→ Choosing from specific sandwiches → which

18. ___ did we see at the movies last week?
→ Person (object of “see”) → technically “whom”, but commonly “who” — however, in formal grammar, since it’s object, it’s whom

BUT — let’s double-check common usage vs. strict grammar.

In most school worksheets today, they accept “who” even for objects unless specifically teaching “whom”. However, since this worksheet includes “whom” as an option and has sentences like #2 and #6 using “To ___”, it seems they want us to use “whom” where grammatically correct.

So for #18: “___ did we see…” — “we” is subject, “see” is verb, blank is object → so whom

But wait — in spoken English, almost everyone says “Who did we see?” — but if this is testing formal grammar, then “whom” is correct.

Looking back at the instructions: “Add an interrogative pronoun to complete each question sentence.” And the list includes “whom”.

Also, #2 and #6 have “To ___” — which clearly requires “whom”.

So for consistency, we’ll use “whom” for object cases.

Final answers:

1. Which
2. Whom
3. Whose
4. What
5. Which
6. Whom
7. Who
8. What
9. Who
10. Whose
11. What
12. Whose
13. Whose
14. Whom
15. What
16. Who
17. Which
18. Whom

Wait — let me check #18 again. In many curricula, especially at elementary level, they may not expect “whom” here. But since the worksheet lists “whom” and uses it in other places, and #18 is clearly object case, I think “whom” is intended.

Alternatively, maybe the worksheet expects “who” for all person questions except after prepositions? Let’s see #7: “___ is the new student...” — subject → who
#9: “___ is going to be...” — subject → who
#16: “___ is the new principal...” — subject → who
#18: “___ did we see...” — object → whom

Yes, that makes sense.

So final list:

1. Which
2. Whom
3. Whose
4. What
5. Which
6. Whom
7. Who
8. What
9. Who
10. Whose
11. What
12. Whose
13. Whose
14. Whom
15. What
16. Who
17. Which
18. Whom

I think that’s accurate.

Final Answer:
1. Which
2. Whom
3. Whose
4. What
5. Which
6. Whom
7. Who
8. What
9. Who
10. Whose
11. What
12. Whose
13. Whose
14. Whom
15. What
16. Who
17. Which
18. Whom
