Difficulty: MediumSentence-Level Transitions

Unlike the visible colors of most flowers, which are produced by chemical pigments, the brilliant blue of a peacock's feather is created by structural coloration. The surface of the feather contains tiny, regular channels that reflect specific wavelengths of light. [1] Nevertheless, this microscopic architecture creates an iridescent shimmer that changes depending on the angle from which it is viewed.

Which of the following choices is the most logical transition to use at the underlined portion marked [1]?

  1. A
    NO CHANGE
  2. As a result,Answer
  3. C
    Similarly,
  4. D
    For instance,

Answer

As a result,
The transition 'As a result,' is correct because it establishes the logical cause-and-effect relationship between the microscopic channels on the peacock's feather and the resulting iridescent shimmer.

Step-by-Step Solution

1
Analyze the relationship between the two sentences separated by the transition.
The first sentence describes the physical structure of the feather (tiny, regular channels that reflect light), and the second sentence describes the visual outcome of this structure (an iridescent shimmer).
Understanding the logical connection between the two ideas is necessary to select the correct transitional phrase.
2
Evaluate the relationship type.
The relationship is cause-and-effect, as the physical channels directly cause the shimmer.
Identifying the relationship type allows you to eliminate transitions that denote contrast, comparison, or illustration.
3
Select the transition that expresses this cause-and-effect relationship.
'As a result,' correctly shows that the shimmer is the direct outcome of the microscopic architecture.
Matching the transition to the cause-and-effect relationship completes the logical flow of the passage.
