B. Compound
C. Compound-complex
D. Simple
Answer:
The sentence above is a B. compound sentence.
Step-by-step explanation:
The sentence we are analyzing here is constituted of two clauses. Let's separate them to better visualize what we have:
1. Other small stores lined both sides of the street for the next few blocks.
2. And Chris quickly scanned the names on the storefronts nearby.
Notice that both clauses make sense on their own, being able to express complete thoughts. That means they are both independent clauses. Also, the second clause is introduced by "and", a coordinating conjunction whose function is precisely to connect independent clauses. When put together, they also need a comma preceding the conjunction. All of those characteristics comprise a compound sentence.
In other words, a compound sentence is the result of joining together two independent clauses connected by a coordinating conjunction.
