## Part 1: Fill in the blanks

1. A simple sentence has one _independent_ clause.
✔ *Explanation:* A simple sentence contains only one independent clause — a group of words with a subject and verb that expresses a complete thought and can stand alone.

2. A compound sentence has two or more _independent_ clauses, and no _dependent_ clauses.
✔ *Explanation:* A compound sentence joins two or more independent clauses (usually with a coordinating conjunction like “and,” “but,” “or”). It does NOT include any dependent (subordinate) clauses.

3. A complex sentence has one _independent_ clause and one or more _dependent_ clauses.
✔ *Explanation:* A complex sentence contains one main (independent) clause and at least one subordinate (dependent) clause, which cannot stand alone and often begins with a subordinating conjunction (e.g., “because,” “although,” “when”).

4. A compound-complex sentence has two or more _independent_ clauses and one or more _dependent_ clauses.
✔ *Explanation:* This sentence type combines features of both compound and complex sentences — it must have at least two independent clauses AND at least one dependent clause.

## Part 2: Identify Sentence Structures

Let’s analyze each sentence and assign the correct number:

> 1 = Simple Sentence
> 2 = Compound Sentence
> 3 = Complex Sentence
> 4 = Compound-Complex Sentence

__2__ 1. Several new kinds of plants sprang up in the garden, but they were not good to eat.
✔ *Two independent clauses joined by “but.” No dependent clauses → Compound.*

__4__ 2. Alice could not think of any good reason, and as the Caterpillar seemed to be in a very unpleasant state of mind, she turned away.
✔ *First clause: “Alice could not think...” (independent). Second clause: “she turned away” (independent). In between: “as the Caterpillar seemed...” (dependent clause). So: 2 independent + 1 dependent → Compound-Complex.*

__3__ 3. During the visit to her mother’s house, the cook threw a frying-pan at her.
✔ *“During the visit...” is a prepositional phrase, NOT a clause. The main clause “the cook threw...” is independent. There’s no other clause → Simple? Wait — actually, this is tricky. But since “during the visit...” is not a clause (no subject + verb), this is just one independent clause → Should be Simple (1).*
⚠️ *Correction needed: This is actually a Simple Sentence (1). “During the visit...” is a prepositional phrase modifying the verb, not a clause. So answer should be 1.*

__3__ 4. The birthday party must be delayed because the dog ate the cake.
✔ *“The birthday party must be delayed” = independent clause. “because the dog ate the cake” = dependent clause → Complex.*

__4__ 5. Although Sara called out for Charlie, no one answered, and Sara was scared.
✔ *“Although Sara called...” = dependent clause. “no one answered” = independent. “Sara was scared” = independent. So: 2 independent + 1 dependent → Compound-Complex.*

__3__ 6. James noticed that the Queen was quickly moving up behind him.
✔ *“James noticed...” = independent clause. “that the Queen was...” = noun clause (dependent) acting as object. → Complex.*

__1__ 7. Some of the jury wrote it down.
✔ *One subject (“Some of the jury”), one verb (“wrote”) → Simple sentence.*

__4__ 8. After he stayed up all night, he finally finished the project that he had put off for three weeks.
✔ *“After he stayed up all night” = dependent clause. “he finally finished...” = independent clause. “that he had put off...” = dependent (relative) clause. So: 1 independent + 2 dependent → Complex? Wait — only one independent clause → Actually, this is Complex (3), not compound-complex.*
⚠️ *Correction: Only one independent clause (“he finally finished...”) + two dependent clauses → Still Complex (3). Not compound-complex unless there are ≥2 independent clauses.*

__3__ 9. The long grass rustled at her feet as the White Rabbit hurried by the garden.
✔ *“The long grass rustled...” = independent. “as the White Rabbit hurried...” = dependent (adverbial clause) → Complex.*

__1__ 10. In the beginning of the novel, Nick arrives in town late at night.
✔ *“In the beginning...” is a prepositional phrase. One independent clause → Simple.*

__2__ 11. The Queen put on her spectacles and began staring at the Hatter, who turned pale and fidgeted.
✔ *“The Queen put on... and began staring...” = compound predicate (same subject, two verbs). “who turned pale...” = dependent relative clause. So: one independent clause + one dependent → Complex?*
⚠️ *Actually, “put on... and began staring” are two verbs sharing the same subject — still one clause. “who turned pale...” is dependent. So → Complex (3). But wait — some might argue it’s compound if you consider “put on” and “began” as separate actions, but grammatically, it’s still one independent clause with a compound verb. So best answer: 3.*

__2__ 12. Alice began in a loud, indignant voice, but she stopped hastily.
✔ *Two independent clauses joined by “but” → Compound.*

__1__ 13. The hedgehog was engaged in a fight with another hedgehog.
✔ *One subject, one verb → Simple.*
