Are the groups of words below simple sentences (S) or compound sentences (C)? Punctuate where necessary. 13. the house needs a furnace and it needs a roof, 14. we believe everything he says, 15. there is no one truth truth is relative

Answer

13. C, the house needs a furnace, and it needs a roof. This is a compound sentence because it consists of two independent clauses ('the house needs a furnace' and 'it needs a roof') joined by the coordinating conjunction 'and'. It requires a comma before the conjunction and a period at the end. 14. S, We believe everything he says. This is a simple sentence because it contains only one independent clause. It only needs to start with a capital letter and end with a period. 15. C, There is no one truth; truth is relative. This is a compound sentence with two independent clauses that are closely related in thought. They can be joined using a semi-colon instead of a conjunction, along with a capital letter at the beginning and a period at the end.
