Expression of Ideas practice question

Some desert plants survive long dry spells by storing water in their own tissue. The barrel cactus, ____ can hold several litres of water in its thick, ribbed stem.

Which choice completes the text with the most logical transition?

  1. A. for example,Correct
  2. B. nevertheless,
  3. C. on the other hand,
  4. D. otherwise,

Answer: A. for example,

The first sentence makes a general claim about desert plants; the second describes one specific plant that does exactly that. The barrel cactus is an example, so 'for example' fits.

Why the other answers are wrong

B. nevertheless,
'Nevertheless' signals that something is true despite what came before. The cactus doesn't defy the first sentence — it illustrates it.
C. on the other hand,
'On the other hand' introduces a contrasting case. The barrel cactus is a case OF water storage, not a contrast to it.
D. otherwise,
'Otherwise' means 'if not'. Nothing here is conditional; the second sentence simply gives an instance of the first.
