Ample sentence:

the gray tones show the bad mood that will be in the country if people do not work hard.

which sentence is the most effective revision of the sample sentence?

the different shades of gray show the bad feeling that will develop if hard work does not occur.
the gray tones show the gray mood that will emerge if factory workers are not working toward victory.
the gray tones reinforce the mood of impending doom that will come if factory workers are not dedicated.

The answer is C

Explanation:

You are not here for an explanation.

The gray tones reinforce the mood of impending doom that will come if factory workers are not dedicated is the correct answer.

Explanation:

In the editing process, revision is the step where changes are made to improve the text or change the tone of it to achieve the main goal of it.

Letter C is the correct option since it respects the idea of the sample sentence and it is also clear for the reader. In option b, the word "gray" is repeated in the same line; while in the first one, there is an awkward sound (not even an alliteration, due to the short repetition of it and purposeless, apparently) when the sentence says "different shades of gray show...," meaning that if we chose this one, the sample sentence wouldn't be totally revised.

b

explanation:

silk

indigo  

rice

all the other answers are wrong
