PASSAGE
The vaccine showed _____ results in preventing the disease.
Which choice completes the text with the most logical and precise word or phrase?
A. promising✓ Correct
B. dangerous
C. disappointing
D. unclear
Detailed Answer Explanation
Choice A is the best answer. "Promising" is correct because it means "showing signs of future success." The context clues in the passage indicate that this meaning best completes the sentence logically.
Why others are wrong: B ("Dangerous" means "likely to cause harm," which doesn't fit the context.), C ("Disappointing" means "failing to meet expectations," which doesn't fit the context.), D ("Unclear" means "not certain," which doesn't fit the context.).
