Set 9: Form, Structure & Sense
Explanation
PASSAGE
The experiment demonstrated that the compound could inhibit tumor growth; _______ further trials are needed to assess its safety for human use.
Which choice completes the text so that it conforms to the conventions of Standard English?
Detailed Answer Explanation
This question tests your understanding of sentence function and text organization. 'However' shows contrast: the compound works, but more trials are needed. The semicolon before and comma after 'however' are correctly placed. 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:
• "could inhibit tumor growth"
• "further trials are needed"
Why others are wrong: C ('Moreover' adds information; the relationship is contrast.), A ('Although' introduces dependent clauses, not independent clauses after semicolons.), D ('Therefore' shows cause-effect; the relationship is contrast.).
