hippos can charge at almost 20 miles per hour and (as if that were not intimidating enough) they sweat red liquid. choose 1 answer: a no change b and—as if that were not intimidating enough, c and, as if that were not intimidating enough d and as if that were not intimidating enough
Answer
Brief Explanations:
- In the original sentence, the phrase "as if that were not intimidating enough" is an aside.
- Dashes are used to set off asides more effectively than just parentheses. Also, a comma is needed after the aside when it is in the middle of a sentence (before "they sweat..."). Option B uses a dash to introduce the aside and a comma after it correctly.
- Option A has parentheses which are less appropriate for this kind of aside in terms of stylistic emphasis.
- Option C is missing the comma after the aside.
- Option D is missing both the dash (to set off the aside clearly) and the comma.
Answer:
B. and—as if that were not intimidating enough,
