PASSAGE
The company made a _____ investment in new technology, expecting significant returns.
Which choice completes the text with the most logical and precise word or phrase?
A. substantial✓ Correct
B. failed
C. minor
D. risky
Detailed Answer Explanation
Choice A is the best answer. "Substantial" is correct because it means "of considerable importance or size." The context clues in the passage indicate that this meaning best completes the sentence logically.
Why others are wrong: B ("Failed" means "unsuccessful," which doesn't fit the context.), C ("Minor" means "small in importance," which doesn't fit the context.), D ("Risky" means "involving danger," which doesn't fit the context.).
