which is the best use of punctuation?
many people are squeamish around, insects, and rodents.
our instructor taught us techniques (to help us) master welding.
upon hearing her diagnosis, she was filled with one emotion: relief.
the children in her afterschool class tend to be immature (and silly).

Explanation:

• In the first option, the comma after "around" is incorrect as it disrupts the flow.
• In the second option, parentheses are misused as "to help us" is essential for the meaning.
• In the fourth option, parentheses are misused as "and silly" is not an aside but an addition to the description.
• In the third option, the colon is correctly used to introduce the specific emotion "relief" after "one emotion".

Answer:

Upon hearing her diagnosis, she was filled with one emotion: relief.
