Difficulty: MediumTransitions: Cause and Effect

Marine biologists have observed that rising ocean temperatures cause kelp forests to lose their structural integrity, making them highly susceptible to storm damage. In regions where ocean temperatures have spiked, kelp canopies have diminished by up to ninety percent. _______, the diverse marine species that rely on these underwater forests for food and shelter have experienced severe population declines.

Which choice completes the passage with the most logical transition?

  1. A
    Additionally
  2. B
    By contrast
  3. As a resultAnswer
  4. D
    Specifically

Answer

As a result
The correct transition is 'As a result' because it establishes the logical cause-and-effect link between the decrease in kelp canopies and the subsequent decline of marine species that depend on them.

Step-by-Step Solution

1
Analyze the relationship between the sentences.
The sentence before the blank states that kelp canopies have declined by ninety percent, and the sentence after the blank states that the marine species relying on these forests have experienced population declines.
Understanding how the ideas connect is necessary to choose the correct transition.
2
Determine the logical flow.
The loss of kelp forests (which provide food and shelter) directly leads to or causes the population declines of the dependent marine species. This is a cause-and-effect relationship.
Identifying the logical relationship allows us to select a transition word that denotes causation.
