How does word choice affect the tone in an informational article ?
a. it makes the purpose of an informational article easier to understand.
b. it changes what readers feel or believe about the topic of the article
c. it has almost no effect on tone of an informational article
d. it provides clues about the authors attitude toward the topic

answer:

b

explanation:

The sentence that is punctuated incorrectly is option D) "The main purpose of parkour is to keep moving forward by combining various movements, (such as the roll, cat leap, precision jump, kong vault, and speed vault)—in a fluid fashion."

The mistake in the sentence is the use of parenthesis after a comma. Another mistake is that after closing a parenthesis, no em dash should be placed.

According to punctuation rules, you can use commas, parenthesis or em dashes to emphasize ideas in a text but you cannot mix those punctuation marks within the same sentence as in this example.

Options A, B and C use punctuation rules correctly.
