A research team is preparing a report on the effectiveness of a new vaccine. The preliminary data shows a 95% efficacy rate, but the team emphasizes that this is based on a small sample size and further large-scale trials are 'imperative' before widespread adoption. What is the team's primary intention in using the word 'imperative'?
- ATo suggest that the vaccine is nearly ready for public use.
- BTo express confidence in the vaccine's long-term safety.
- CTo downplay the significance of the preliminary results.
- DTo highlight the critical need for additional testing.
Show answer & explanationAnswer & explanation
Correct answer: D. To highlight the critical need for additional testing.
The word 'imperative' means of vital importance or crucial. By stating that large-scale trials are 'imperative,' especially after mentioning the small sample size, the team is emphasizing that these further trials are absolutely necessary and critical before moving forward with widespread adoption.
Why the other options are wrong
- A. Using 'imperative' for further trials suggests caution and a need for more data, not that the vaccine is nearly ready.
- B. The statement focuses on the need for more testing, not on expressing confidence in long-term safety, which is yet to be fully established.
- C. While cautious, the use of 'imperative' for further trials doesn't downplay the 95% efficacy but rather ensures robust validation of it.
Imperative
Of vital importance; crucial.
- Indicates extreme necessity or urgency.
- Often used in formal or serious contexts.
