which sentences are punctuated correctly? choose two correct answers.

that sculpture which is made of scrap metal was designed by an older artist.
the astronauts on the mission were all experienced.
one sport that i would like to learn is hockey.
the bicycle—that has the best brakes—is a european brand.

Explanation:

1. For the sentence "The astronauts on the mission were all experienced.": It contains no restrictive/non-restrictive clauses requiring special punctuation, so its punctuation is correct.
2. For the sentence "One sport that I would like to learn is hockey.": The clause "that I would like to learn" is a restrictive essential clause, which does not need commas, so its punctuation is correct.
3. For "The dog (that was barking) was a St. Bernard.": Restrictive clauses use "that" and do not need parentheses; parentheses are for non-essential asides, so this is incorrect.
4. For "That sculpture which is made of scrap metal was designed by an older artist.": Non-restrictive clauses use "which" and require commas around them, so this is incorrect.
5. For "The bicycle—that has the best brakes—is a European brand.": Restrictive clauses use "that" and do not need em dashes, so this is incorrect.

Answer:

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