Which choice completes the text so that it conforms to the conventions of Standard English?
For difficult boundary questions, locate the main subject and verb before evaluating punctuation. Then identify any relative or parenthetical clause interrupting that core structure, determine exactly where the interruption ends, and choose punctuation that closes it without improperly splitting a subject, verb, or other essential construction.
Hints
Find the main subject and verb
Temporarily set aside the descriptive material beginning with “which” and determine what performs the action expressed by “show.”
Trace the first relative clause
Identify exactly where the clause beginning with “which transforms” ends.
Preserve the compound subject
Choose a boundary that closes the interruption after “novel” without separating the sentence’s main subject from its second coordinated element.
Step-by-step Explanation
Identify the main sentence structure
Set aside the descriptive clauses to find the sentence’s core: “Guadalupe Marín’s novel and her sculptures ... show how she worked across artistic media.” The main subject is the compound subject “novel and sculptures,” and its verb is “show.”
Identify the first relative clause
The words “which transforms some of her experiences into fiction” form a nonessential relative clause describing the novel. The comma after “novel” marks the beginning of this interruption.
Close the interruption
Because the relative clause ends with “fiction,” a comma must follow that word to close the interruption. The sentence can then continue with the second part of the compound subject: “and her sculptures.”
Verify the completed structure
The resulting structure is “Guadalupe Marín’s novel, which transforms some of her experiences into fiction, and her sculptures ... show.” The paired commas properly set off the relative clause while preserving the compound subject.
