How should I approach this reading question type?

First, identify the core claim of the text. Look for transition words like 'however' or 'furthermore' which signal changes in the author's logic. Then, match the evidence directly to the options provided.

What is the common trap in wrong answers for this category?

The most common trap is 'extreme language' (e.g., 'always', 'never') or 'unsupported inferences' that go beyond what is explicitly stated in the provided text snippet.

Why is the correct answer better than the close alternatives?

The correct answer usually captures the most direct and necessary evidence from the text, whereas alternatives often focus on minor details or distort the author's primary subject.

Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. The participial phrase 'observable only under specific atmospheric conditions' is parenthetical. A comma closes this phrase before the main verb 'has been documented.' 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 phenomenon, observable only under"

• "has been documented fewer than a dozen times"

Why others are wrong: A (A colon doesn't fit for closing a participial phrase.), B (A semicolon is too strong for closing a participial phrase.), C (Missing punctuation fails to close the parenthetical phrase.).
