Answer:
As much as water is an endangered resource, we cannot live without it.
Explanation:
A compound sentence is a sentence that has two independent clauses, meaning there should be a conjunction to connect the two clauses (FANBOYS) or a semicolon.
A complex sentence has one independent clause and one dependent clause.
Note that independent clauses can stand alone as a sentence, meaning they have both a subject and a predicate.
On the other hand, a dependent clause can not stand alone as a sentence, has both a subject and verb, and will most often start with a subordinating conjunction.
We have the sentence:
Water is an endangered resource and we cannot live without it.
We can make it:
As much as water is an endangered resource, we cannot live without it.
As much as is the subordinating conjunction that makes the first clause dependent.
"We cannot live without it" is the independent clause.
You can remove "As much as" and replace it with any subordinating conjunction that makes sense, it's just hard to find a perfect replacement for the conjunction "and."
