Hello. I'll give this a try.

1. Important (Think of something being important. Carbohydrates, for instance, are important foods because they supply energy, etc.)

2. I think "so" would work here (because it can mean the imagination has been fired to a great degree)

3. several? ("Simple" needs a word in front of it, in order to be correct.)

4. primarily (an adverb telling something about "consisting") (See number 7, also.)

5. so? ("Yet" doesn't work because it doesn't help explain what follows it, and "yet that" seems ungrammatical. "So that" could mean that the layers are formed IN THIS WAY or IN SUCH A MANNER THAT...)

6. [u]the[/u] first ten years

7. primarily (an adverb telling something about how jetties are constructed) "Primary" is an adjective, which is not what you want here. It's correct to say something like a primary color, a primary reason, a primary school...but if you are modifying a verb, you need "primarily" rather than "primary." (See number 4, also.)

I think number 2 is "as": nothing has as much fired as space.

Number 3 could be "of the most simple", although the sentence makes no sense then.
