gay

Explanation:

A.) Combined

Explanation:

This answer makes the most sense. Suppose we have a sentence like, "I went to the ice cream parlor.", and another sentence that said, "It was fun.". We can combine these two sentences to form a compound sentence, such as, "I went to the ice cream parlor, and it was fun."

1. b

2. a deadly disease

4. at the same time

5. a) true

b) true

c)false?

d)false?

7. para.1 = c

para.2 = d

para.3 = f

para.4= b

para.5= e

para.6 = a

this is a good question! i'll do some research and come back when i have the answer!
