PASSAGE
Researchers have observed that vincent van Gogh's paintings are valued at millions of dollars _______ during his lifetime, he sold only one painting.
Which choice completes the text so that it conforms to the conventions of Standard English?
Detailed Answer Explanation
[Variation 3] This question tests your understanding of sentence function and text organization. 'However' is a conjunctive adverb joining two independent clauses. It needs a semicolon or period before it and a comma after it. Since there's no period option, 'today, however,' uses commas to set off 'however.' Each sentence in a well-constructed text serves a specific purpose. Consider what role this sentence plays in the argument: does it introduce, support, contrast, or conclude an idea? Understanding why an author includes specific sentences helps you grasp the overall argument. Each sentence should serve a clear purpose: introducing ideas, providing evidence, acknowledging counterarguments, or drawing conclusions. Identify the role to understand the structure.
Key Evidence:
• "are valued at millions of dollars"
• "during his lifetime, he sold only one painting"
Why others are wrong: D ('However' needs commas on both sides when used as an interrupter.), C (Missing the comma after 'however' creates a comma splice.), A (Missing the comma before 'however' is incorrect punctuation.).
