Difficulty: EasyPunctuation of Nonessential Elements

The following passage is an excerpt from an art history essay. Complete the passage by typing the punctuation mark that correctly fills the blank to ensure standard English conventions.

Answer:The American artist Mary Cassatt was celebrated for her intimate portraits of mothers and children, which departed from traditional European portraiture. Her famous painting *The Child's Bath*, which she completed in 1893【,】 showcases her mastery of Japanese woodblock print techniques through its bold lines and unique perspective. By emphasizing domestic scenes, Cassatt helped introduce Impressionist ideas to a broader American audience.

Answer

A comma (,) is required to close the nonessential relative clause.
The clause 'which she completed in 1893' is a nonessential relative clause describing the painting *The Child's Bath*. To correctly set off this nonessential element, the punctuation must be symmetrical. Since the clause is introduced by a comma after the painting's title, it must also be closed with a comma before the main verb 'showcases'.

Step-by-Step Solution

1
Identify the nonessential element in the sentence.
The clause 'which she completed in 1893' is a nonessential relative clause because removing it does not change the core meaning of the main sentence.
Nonessential elements must be set off from the main clause with punctuation on both sides.
2
Examine the punctuation that opens the nonessential element.
The clause begins after a comma: 'Her famous painting *The Child's Bath*, which...'
This establishes that commas are the chosen punctuation style for setting off the nonessential element.
3
Select the matching punctuation mark to close the nonessential element.
A matching comma (,) must be placed at the end of the clause before the main verb 'showcases'.
Punctuation marks setting off nonessential elements must be symmetrical (comma-comma).
