Set 6: Form, Structure & Sense (Advanced)
Explanation
PASSAGE
The vaccine's effectiveness, as measured in clinical trials, _______ expectations, with protection rates exceeding 90 percent.
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. 'The vaccine's effectiveness' is singular. The phrase 'as measured in clinical trials' is parenthetical. 'Exceeded' (past tense) describes completed trial results. 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:
• "The vaccine's effectiveness"
• "as measured in clinical trials"
Why others are wrong: B ('Exceed' is plural; 'effectiveness' is singular.), C ('Exceeding' is a participle; the sentence needs a main verb.), D ('Have exceeded' is plural; 'effectiveness' is singular.).
