Set 5: Inferences
Explanation
PASSAGE
The bombardier beetle defends itself by mixing two chemicals in its abdomen that create a boiling-hot, explosive spray. The beetle can aim this spray with remarkable precision and fire multiple times in succession.
What can be inferred about the bombardier beetle's defense mechanism?
Detailed Explanation
This question asks you to draw a logical conclusion from the text. Mixing chemicals, aiming precisely, and firing multiple times = active, sophisticated, controlled. A valid inference must be supported by evidence in the passage, even if not stated directly. Look for clues in the text that strongly suggest the answer. Avoid conclusions that require assumptions beyond what's written. Valid inferences are strongly supported by multiple pieces of evidence in the text. Be cautious of choices that go too far beyond what the passage actually states. The best inference is the one most directly supported by textual evidence.
Key Evidence:
• "aim with remarkable precision"
• "fire multiple times in succession"
Why others are wrong: B (It's an active spray, not camouflage.), C (It fires 'multiple times.'), D ('Boiling-hot, explosive' implies effectiveness.).
