Question

which answer best corrects the sentence by adding dashes?

martin fascinated by the storm watched as thunder boomed and lightening split the sky.

a martin fascinated by the storm watched as thunder boomed- and lightening split the sky.

b martin-fascinated by the storm watched as thunder boomed and lightening split the sky.

c martin- fascinated by the storm- watched as thunder boomed and lightening split the sky.

d martin fascinated by the storm-watched as thunder boomed and lightening split the sky.

Explanation:

Dashes set off non-essential descriptive phrases. Here, "fascinated by the storm" is an extra detail about Martin, so it needs to be enclosed between two dashes to properly separate it from the main clause "Martin watched as thunder boomed and lightening split the sky." The other options either place dashes incorrectly or fail to properly set off the descriptive phrase.

Answer:

C. Martin- fascinated by the storm- watched as thunder boomed and lightening split the sky.
