Analyze restrictive and nonrestrictive clauses

To determine which sentences are punctuated correctly, we must evaluate whether the clauses are restrictive (essential to the meaning of the sentence) or nonrestrictive (nonessential information).

• Restrictive clauses limit or define the noun they modify and should not be set off by punctuation (such as commas, parentheses, or dashes).
• Nonrestrictive clauses add extra, nonessential information and must be set off by punctuation.

Let's evaluate each sentence:

1. The dog (that was barking) was a St. Bernard.

• The clause "that was barking" is a restrictive relative clause because it specifies which dog is being discussed. Restrictive clauses using "that" should not be set off by parentheses. Thus, this sentence is incorrectly punctuated.

1. That sculpture which is made of scrap metal was designed by an older artist.

• The clause "which is made of scrap metal" is nonrestrictive here because "That sculpture" already specifies which sculpture is being referred to. Nonrestrictive clauses starting with "which" must be set off by commas. Since there are no commas, this sentence is incorrectly punctuated.

1. The astronauts on the mission were all experienced.

• The prepositional phrase "on the mission" is restrictive because it specifies which astronauts are being discussed. It is correctly left unpunctuated. Thus, this sentence is correctly punctuated.

1. The bicycle—that has the best brakes—is a European brand.

• The clause "that has the best brakes" is restrictive. Restrictive clauses should not be set off by em dashes. Furthermore, "that" is not used for nonrestrictive clauses set off by dashes or commas (which would require "which"). Thus, this sentence is incorrectly punctuated.

1. One sport that I would like to learn is hockey.

• The clause "that I would like to learn" is a restrictive relative clause that defines "One sport." It is correctly left unpunctuated. Thus, this sentence is correctly punctuated.

Identify the correct options

Based on the analysis:

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