Question

Read the sentence.

Henry David Thoreau, often known as the father of environmentalism wrote the book entitled Walden.

Which revision should be made so that the sentence is properly punctuated?

place a dash after “environmentalism”
remove the comma after “Thoreau”
place parentheses around “entitled Walden”
add a comma after “environmentalism”

Answer 1

Add the comma after “environmentalism”

Answer 2

The correct punctuation to the above sentence is the fourth option, which says to add a comma after environmentalism.

That is because, the subject of the sentence is Henry David Thoreau, and the verb here is wrote.

Hence, a comma needs to seperate father of environmentalism and wrote, which is the verb.
