Question

Difficulty: MediumTransitions: Cause and Effect

What transition word or phrase best completes the blank to establish the correct relationship between the sentences?

Answer:In the high-altitude forests of the Andes, frequent cloud cover reduces the amount of direct sunlight that reaches the canopy. Plants in these ecosystems have adapted by developing leaves with higher chlorophyll concentrations to maximize light absorption. 【consequently】, many cloud forest species exhibit darker green foliage than their counterparts in lower, sunnier elevations.

Answer

A cause-and-effect transition such as 'consequently', 'therefore', 'thus', 'accordingly', or 'as a result'
The passage establishes a cause-and-effect relationship: the adaptation of producing more chlorophyll causes the leaves to have a darker green color. Therefore, a cause-and-effect transition like 'consequently', 'therefore', 'thus', 'accordingly', or 'as a result' is required to connect these ideas logically.

Step-by-Step Solution

1
Analyze the relationship between the sentences preceding and following the blank.
The first part of the passage states that plants in high-altitude forests adapt to low light by developing higher chlorophyll concentrations. The second part states that these plants exhibit darker green foliage.
Understanding the semantic connection between the two ideas is necessary to determine the correct logical transition.
2
Determine the logical flow between the adaptation (higher chlorophyll) and the physical appearance (darker foliage).
Having higher chlorophyll concentrations directly causes the foliage to appear darker green. The second idea is the result of the first.
Identifying the relationship as cause-and-effect guides the selection of the transition.
3
Choose a transition word or phrase that denotes cause-and-effect.
Words like 'consequently', 'therefore', 'thus', 'accordingly', or the phrase 'as a result' logically connect the sentences.
These transitions signal to the reader that the subsequent statement is a consequence of the preceding facts.
