Set 1: Text Structure (Intermediate)
Explanation
PASSAGE
While many assume that all bacteria are harmful, most are actually benign or even beneficial. For instance, the bacteria in our gut are essential for digestion. Without them, our bodies would struggle to process food efficiently.
Which choice best describes the function of the second sentence?
Detailed Answer Explanation
This question tests your understanding of how the text is organized. Sentence 1 claims most bacteria are helpful. Sentence 2 gives an example ('For instance, bacteria in our gut'). Authors structure their writing purposefully to guide readers through their ideas. Identify the organizational pattern (cause-effect, compare-contrast, problem-solution) and how each part contributes to the whole. Authors choose organizational patterns deliberately to enhance their message. Recognizing whether a text uses chronological order, cause-effect, compare-contrast, or problem-solution helps you understand the author's purpose and follow the logic.
Key Evidence:
• "most are actually benign or even beneficial"
• "For instance"
Why others are wrong: B (It's a supporting detail, not the summary.), C (It supports the claim, doesn't counter it.), D (It talks about digestion, not infection.).
