🔍 Definitions:

- Simple Sentence: One independent clause (one subject and one predicate).
- Compound Sentence: Two or more independent clauses joined by a coordinating conjunction (e.g., *and, but, or*) or a semicolon.
- Complex Sentence: One independent clause + one or more dependent clauses (starts with subordinating conjunctions like *because, although, since, when, if*, etc.).

Now let’s go through each sentence:

---

1. My phone is dead because I forgot to plug it in last night.
→ "My phone is dead" (independent) + "because I forgot..." (dependent clause).

2. The lead in my pencil broke, but I can use this pen.
→ Two independent clauses: "The lead...broke" and "I can use this pen", joined by "but".
✔ Compound (C)

3. You need to take a shower before you go to bed tonight.
→ "You need to take a shower" (independent) + "before you go..." (dependent clause).
✔ Complex (X)

4. I want to give my grandma a gift for her birthday.

✔ Simple (S)

5. I lost my tooth while I was eating an apple today!
→ "I lost my tooth" (independent) + "while I was eating..." (dependent clause).

6. As soon as Gina finished planting her flowers, it started to rain.

8. My library book was overdue, so I had to pay a fine.

✔ Compound (C)

9. Track is Mason’s least favorite sport, yet it’s the sport he most excels at.
→ Two independent clauses: "Track is Mason’s least favorite sport" and "it’s the sport he most excels at", joined by "yet".
✔ Compound (C)

10. Unless I receive an email from Jill by tomorrow morning, I am going to proceed with planning the party myself.
→ "I am going to proceed..." (independent) + "Unless I receive..." (dependent clause).
✔ Complex (X)

11. After reading news headlines by the campfire, Lee told ghost stories.
→ "Lee told ghost stories" (independent) + "After reading..." (dependent phrase).
✔ Complex (X)

12. I have an announcement to make when everyone arrives.
→ "I have an announcement to make" (independent) + "when everyone arrives" (dependent clause).
✔ Complex (X)

13. Although Leo was fortified, he refused to let me leave.

✔ Complex (X)

14. If we don’t quiet down, my mom will never let me have a slumber party again.
→ "my mom will never let me have..." (independent) + "If we don’t quiet down" (dependent clause).
✔ Complex (X)

15. The baby was cranky, so I put her down for a nap.
→ Two independent clauses: "The baby was cranky" and "I put her down...", joined by "so".
✔ Compound (C)

16. I can no longer eat sticky foods like licorice, I have braces now.
→ This is actually two independent clauses separated by a comma, but no conjunction — this is a comma splice, which is a grammatical error. However, since the question is about sentence type, we classify based on structure:
→ Two independent clauses without proper punctuation/conjunction → Compound (C) (even though it's incorrect grammar).
✔ Compound (C)

17. Although I suspected I was wrong, I refused to admit my mistake.
→ "I refused to admit my mistake" (independent) + "Although I suspected..." (dependent clause).
✔ Complex (X)
