PASSAGE
The new Mars rover is designed to be ______, capable of withstanding the harsh dust storms and freezing temperatures of the Martian surface without malfunctioning.
Which choice completes the text with the most logical and precise word or phrase?
A. resilient✓ Correct
B. fragile
C. temporary
D. delicate
Detailed Explanation
The rover needs to 'withstand' harsh conditions like storms and freezing settings. 'Resilient' means able to withstand or recover quickly from difficult conditions.
Key Evidence:
• "withstanding"
• "harsh dust storms"
• "without malfunctioning"
Why others are wrong: B (Fragile means easily broken, which is the opposite of what is needed.), C (Temporary implies it won't last, but the context emphasizes survival/durability.), D (Delicate is similar to fragile and means easily damaged.).
