Answer:
Passage C.
Explanation:
Let's take a look at the other passages.
Passage A only uses simple sentence structures and all sentences are of simillar length.
Passage B only uses compound sentence structures, and all sentences are of similiar length.
Passage D uses both simple and compound sentence structures but no complex ones. Sentence length is varied.
But Passage C uses all four sentence structures: simple, compound, complex, and compound-complex. Sentence length is varied.
Sentence Structures:
S i m p l e
A simple sentence consists of one independent clause. (An independent clause contains a subject and verb and expresses a complete thought.)
Example: I like coffee.
C o m p o u n d
A compound sentence is two (or more) independent clauses joined by a conjunction or semicolon. Each of these clauses could form a sentence alone.
Example: I like coffee, and she likes tea.
There are seven coordinating conjunctions:
for, and, nor, but, or, yet, so. FANBOYS is a mnemonic device, which stands for these coordinating conjunctions.
C o m p l e x
A complex sentence consists of an independent and a dependent clause. A dependent clause starts with a subordinating conjunction, contains a subject and verb, but does not express a complete thought.
Example: Although I like coffee, she likes tea.
C o m p o u n d - C o m p l e x
A compound-complex sentence consists of at least two independent clauses and one or more dependent clauses.
Example: I drink coffee because I like it, but she likes tea.
