Explanation

Answer: A

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?

A. however,✓ Correct
B. although,
C. therefore,
D. moreover,

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: D ('Moreover' adds information; the relationship is contrast.), B ('Although' introduces dependent clauses, not independent clauses after semicolons.), C ('Therefore' shows cause-effect; the relationship is contrast.).
