Question

Difficulty: EasyTransitions: Contrast and Concession

Many desert plants adapt to dry climates by storing water in their stems or leaves to survive prolonged periods without rain. The resurrection fern (*Pleopeltis polypodioides*), _______, takes a different approach: it can lose up to 97% of its water content and survive in a desiccated, dormant state for years. When exposed to moisture, the shriveled, brown leaves of the fern absorb water and return to their vibrant green color within hours.

Which choice completes the passage with the most logical transition?

  1. A
    in fact
  2. by contrastAnswer
  3. C
    therefore
  4. D
    furthermore

Answer

by contrast
The correct answer is 'by contrast' because the passage establishes a contrast between the water-storing adaptation of most desert plants and the desiccation-survival adaptation of the resurrection fern. The phrase 'takes a different approach' in the second sentence further signals that a contrast transition is needed.

Step-by-Step Solution

1
Analyze the relationship between the first and second sentences of the passage.
The first sentence explains that many desert plants survive by storing water, while the second sentence explains that the resurrection fern survives by losing water.
Identifying the logical flow is necessary to select the correct transition.
2
Identify the type of logical relationship.
The relationship is one of contrast, as the two strategies are opposites.
Determining the relationship type helps narrow down the correct transition word or phrase.
3
Evaluate the choices to find the one that signals a contrast relationship.
The transition 'by contrast' correctly signals a contrast relationship. The other choices signal elaboration, cause-and-effect, and addition, which do not fit the context.
Choosing the word that reflects the identified logical relationship completes the passage logically.
