The sentence would be a compound sentence, I believe.
The first statement is a statement of fact because there is no opinion in it
Cloning humans:
pros- less work for an individual, maybe not completely cloning someone so like picking desirable traits in a person and changing that
cons- possible overthrowing of the "real" copy, families who have exact copies of each parent may end in incest, or even selfcest
But we already live in a world where there are real life clones. Twins, and triplets. I believe there's a Brain Games episode that discuss this topic.
The answer should be D because the word "was" almost always makes the sentence past tense. (Im sorry if this is not correct but it should be, Im not the smartest cup of tea)
