PASSAGE
Though the two theories appear contradictory, they are actually ______; each explains a different aspect of the phenomenon without negating the other.
Which choice completes the text with the most logical and precise word or phrase?
A. incompatible
B. complementary✓ Correct
C. redundant
D. identical
Detailed Explanation
If they work together to explain different aspects without conflict ('negating'), they fit together. 'Complementary' means combining in such a way as to enhance or emphasize the qualities of each other or another.
Key Evidence:
• "explains a different aspect"
• "without negating"
Why others are wrong: A (Incompatible means they can't work together.), C (Redundant means repeating the same thing.), D (Identical means exactly the same.).
