Let’s go through each sentence pair and pick the best conjunction to combine them into one smooth compound sentence.
We have these choices:
and, or, but, for, yet
Remember:
-
and = adds something similar or continuing
-
or = gives a choice
-
but / yet = shows contrast (something unexpected)
-
for = means “because” — explains why
Now let’s solve each one:
---
1. *I met a genie. He offered me three wishes.*
→ These two things happened together — meeting the genie led to getting wishes. No contrast, no choice. Just adding info.
✔ Use
and
→ I met a genie, and he offered me three wishes.
---
2. *I ate a big lunch. I am still hungry.*
→ You’d think after a big lunch you wouldn’t be hungry — but you are! That’s a surprise → contrast.
✔ Use
but or
yet — both work. Let’s pick
but (more common).
→ I ate a big lunch, but I am still hungry.
---
3. *One door closed. Another one opened.*
→ One thing ended, another started — often used to show balance or replacement. Not really contrast, more like sequence or parallel action.
✔ Use
and
→ One door closed, and another one opened.
*(Note: Some might say “but” if they want to emphasize change — but “and” is smoother here since it’s neutral.)*
---
4. *I may have a burger. I may have a pizza.*
→ This is giving yourself options — you can pick one or the other.
✔ Use
or
→ I may have a burger, or I may have a pizza.
---
5. *I called my mother. I knew she would worry.*
→ Why did you call? Because you knew she’d worry? Actually, this sounds like you called EVEN THOUGH you knew she’d worry — that’s contrast.
Wait — actually, re-read: “I called my mother. I knew she would worry.”
It could mean: I called her, and I was aware she’d worry — so maybe just adding info? But usually, we use “even though” for that — which isn’t an option.
Alternatively, maybe it’s explaining WHY you didn’t call? But the sentence says you DID call.
Actually, looking again — perhaps it’s meant to be: I called her, FOR (because) I knew she’d worry? That doesn’t make sense — why would you call because she’d worry?
Better interpretation: You called her, BUT you knew she’d worry — meaning you did it anyway despite knowing the result.
✔ So use
but
→ I called my mother, but I knew she would worry.
*(This is tricky — but “but” fits best as it shows you acted even though you expected a negative reaction.)*
---
6. *I called my mother. She still worried.*
→ You called — maybe to reassure her — but she worried anyway. Contrast between your action and her reaction.
✔ Use
but or
yet — let’s use
yet for variety.
→ I called my mother, yet she still worried.
---
7. *The car is fixed. It’s running great again.*
→ The second part is a happy result of the first — no contrast, just continuation.
✔ Use
and
→ The car is fixed, and it’s running great again.
---
Final check: All sentences now flow naturally with the right conjunction showing the relationship between ideas.
