Explanations

These explanations were written by Erin Billy.

1. D Simple sentence: microscope can reveal detail

We need to make a comparison using more... than...

2. A Simple sentence: bulbs should be planted

We need a main verb here. We should use active voice because we have no object here.

3. B Simple sentence: industrialization has been responsible

We should use the when we have a superlative functioning as a pronoun.

4. D Simple sentence: slope and topography do not permit rainfall to run off

We need a main verb here.

5. A Simple sentence: color and light influence impact

This is a word order question. In this sentence, very modifies powerfully. Together, the adverb phrase very powerfully modifies the verb influence.

6. C Simple sentence: it is likely

B: We have a reduced adjective clause here.

C: We should say that is a rare condition

7. B Simple sentence: blindness is result

Nothing is missing from this sentence, so we should add something optional and complete. In this case, we are adding a reduced adjective clause.

8. C Simple sentence: experts believe [that wheel was invented and diffused]

We need a subordinating conjunction here since we have two sentences.

9. A Simple sentence: life is abundant

We need a main complement here. We cannot use the abundance here because the meaning is illogical.

S: What does abundant mean?

T: plentiful. In other words we use this this word to say that we have a lot of something.

10. C Simple sentence: Isadora Duncan was [what we would call woman]

C: We have a noun clause functioning as a main complement.

11. B Simple sentence: the smallest creates currents

Nothing is missing from this sentence. Therefore, we should add something optional and complete. (B) is a great choice because it is a complete adverb clause.

12. B Simple sentence: music has features

D: The easiest way to see that this is wrong is to look at features and gives--they do not agree.

13. B Simple sentence: most is based on studies

We need a subordinate object here. In this case, we are using what in a noun clause.

A: We would have a double verb here.

C: which usually functions as a determiner in a noun clause.

D: We would have a double verb here.

14. D Simple sentence: novels demonstrate hazard

First of all, we need a determiner for the singular count noun tendency. We have a reduced adjective clause here.

C: We would have an extra verb here.

15. A Simple sentence: one was coinciding

We should see that we need a main verb. We should therefore choose (A) or (C). If we choose (C), we would have no main subject.
