Explanation
PASSAGE
The study of astronomy requires patience, _______ celestial events often occur over vast timescales.
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. 'Because' introduces a reason. The second clause explains why astronomy requires patience (events occur over vast timescales). 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:
• "requires patience"
• "celestial events often occur over vast timescales"
Why others are wrong: B ('However' shows contrast, but the two clauses have a causal relationship.), D ('Although' shows contrast; the relationship here is causal.), C ('Therefore' indicates result; the second clause is a cause, not result.).
