Difficulty: EasyTransitions: Contrast and Concession

Coral reefs occupy less than one percent of the ocean floor. ______ they support more than twenty-five percent of all marine life, making them some of the most biodiverse ecosystems on Earth.

Which choice completes the passage with the most logical transition?

  1. A
    Furthermore
  2. NeverthelessAnswer
  3. C
    Therefore
  4. D
    Subsequently

Answer

Nevertheless
The correct option is the transition that indicates a concession or contrast. The passage contrasts the very small physical space occupied by coral reefs (less than one percent of the ocean floor) with the very large percentage of marine species they support (more than twenty-five percent). The transition 'Nevertheless' correctly signals this concession, indicating that despite the small area, the reefs support a massive amount of biodiversity.

Step-by-Step Solution

1
Analyze the relationship between the two ideas in the passage.
The first sentence states that coral reefs occupy a very small percentage of the ocean floor (less than one percent). The second sentence states that they support a very large percentage of marine life (more than twenty-five percent). This creates a contrast or concession, as a small area supporting a huge amount of life is unexpected.
Identifying the logical connection between the ideas is necessary to choose the correct category of transition word.
2
Evaluate the categories of transition words offered in the choices.
'Furthermore' represents addition, 'Therefore' represents cause-and-effect, 'Subsequently' represents sequence, and 'Nevertheless' represents contrast or concession.
Categorizing the options helps match the correct logical relation to the choices.
3
Select the choice that matches the identified relationship.
'Nevertheless' is a transition of concession/contrast that perfectly fits the unexpected relationship between the two facts.
Choosing the transition that expresses contrast or concession is the final step to complete the sentence logically.
