Expression of Ideas practice question

The vaccine trial enrolled forty thousand volunteers across six countries. ____ its authors caution that people over seventy were underrepresented among them.

Which choice completes the text with the most logical transition?

  1. A. Still,Correct
  2. B. As a result,
  3. C. For example,
  4. D. In other words,

Answer: A. Still,

The first sentence emphasises the trial's size; the second notes a weakness that remains despite it. 'Still' signals that a qualification holds in spite of what came before.

Why the other answers are wrong

B. As a result,
'As a result' would make the underrepresentation a consequence of the large enrolment. It's a limitation the size doesn't fix, not something the size caused.
C. For example,
'For example' would present the caution as an example of the large enrolment.
D. In other words,
'In other words' would make the caution a restatement of the trial's size.
