Explanation
PASSAGE
The bacterial strain proved ______ to the new antibiotic, continuing to proliferate despite high concentrations of the drug.
Which choice completes the text with the most logical and precise word or phrase?
Detailed Answer Explanation
This question asks for the meaning of a word as used in this specific context. If it continues to grow ('proliferate') despite the drug, the drug isn't working. 'Impervious' means unable to be affected by. Words can have multiple meanings, and context determines which meaning applies. Read the surrounding sentences carefully. Substitute each answer choice to see which maintains the intended meaning and fits the context. Many vocabulary words have multiple dictionary definitions, but only one fits the context. Use the surrounding sentences as clues. Try substituting each answer choice to see which one preserves the author's intended meaning without changing the sentence's message.
Key Evidence:
• "continuing to proliferate"
• "despite high concentrations"
Why others are wrong: C (Conducive means helpful.), A (Symbiotic implies a mutually beneficial relationship.), D (Susceptible means easily harmed by.).
