PASSAGE
Photosynthesis _______ plants to convert sunlight into energy, a process essential for nearly all life on Earth.
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 subject 'Photosynthesis' is singular and requires the singular present tense verb 'allows.' This describes a general scientific fact. 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:
• "Photosynthesis"
• "plants to convert sunlight"
Why others are wrong: A ('To allow' is an infinitive; the sentence needs a finite verb.), B ('Allowed' is past tense; the sentence describes an ongoing process.), C ('Allowing' is a participle, not a main verb.).
