Show Answer Key & Explanations Step-by-step solution for: Conjunctions Grade 3 online exercise for
Let's solve each sentence by choosing the correct conjunction and explaining why it fits best.

---

1. I don't have much time, ________ hurry up!

- Options: so, but, and

Correct answer: so

🔹 Explanation: "So" shows a cause-and-effect relationship. Because the speaker doesn’t have much time, they are telling someone to hurry up.
👉 "I don't have much time, so hurry up!" – This makes logical sense.

*But* would imply contrast (e.g., "I don't have much time, but I'm not in a rush"), which doesn’t fit.
*And* doesn’t show the reason for hurrying.

2. He has won a lot of rewards, ________ he is still unhappy.

- Options: and, but, or

Correct answer: but

🔹 Explanation: There’s a contrast here — he has achieved success (won many rewards), yet he’s unhappy.
👉 "He has won a lot of rewards, but he is still unhappy." – This highlights the unexpected result.

*And* would suggest both things are true without contrast, which weakens the meaning.
*Or* is used for choices, not contrasting ideas.

---

3. We can go to the movies, ________ we can go to the park.

- Options: or, and, but

Correct answer: or

🔹 Explanation: The sentence presents two possible options — going to the movies or going to the park.
👉 "We can go to the movies, or we can go to the park." – This clearly shows a choice.

*And* would suggest both activities happen together, which isn’t implied.
*But* introduces contrast, which isn’t present here.

---

4. She was sick, ________ she still went to work.

- Options: but, and, or

Correct answer: but

🔹 Explanation: There’s a contrast between being sick (which would normally prevent going to work) and still going.
👉 "She was sick, but she still went to work." – This emphasizes the unexpected action.

*And* would just list facts without highlighting the contrast.
*Or* doesn’t make sense in this context.

---

5. I went to the store ________ bought tomatoes.

- Options: and, but, so

Correct answer: and

🔹 Explanation: These are two actions that happened in sequence: going to the store and buying tomatoes.
👉 "I went to the store and bought tomatoes." – This shows continuation.

*But* implies contrast (e.g., "I went to the store but didn’t buy anything"), which doesn’t fit.
*So* suggests a reason (e.g., "I was hungry, so I bought tomatoes"), but no cause is given.

---

Final Answers:


1. so
2. but
3. or
4. but
5. and

Each choice reflects the logical relationship between the clauses: cause-effect, contrast, choice, or sequence.
