Question

which sentences are punctuated correctly? choose two correct answers. that sculpture which is made of scrap metal was designed by an older artist. the dog (that was barking) was a st. bernard. the astronauts on the mission were all experienced. the bicycle—that has the best brakes—is a european brand. one sport that i would like to learn is hockey.

Explanation:

1. In "That sculpture which is made of scrap metal was designed by an older artist", "which" clause should be set off by commas as non - essential information, so it's incorrect.
2. In "The dog (that was barking) was a St. Bernard", parentheses are misused; "that was barking" is essential information and should not be in parentheses.
3. "The astronauts on the mission were all experienced" has no punctuation errors as it is a simple, well - formed sentence.
4. In "The bicycle—that has the best brakes—is a European brand", em dashes are misused; "that has the best brakes" is essential information and doesn't need em dashes.
5. "One sport that I would like to learn is hockey" has no punctuation errors as it is a straightforward sentence with an essential relative clause.

Answer:

The astronauts on the mission were all experienced.
One sport that I would like to learn is hockey.
