Difficulty: MediumSentence-Level Transitions

Many architectural historians praise the geodesic dome, popularized by Buckminster Fuller in the mid-twentieth century, for its structural efficiency and modern aesthetic. The dome distributes stress evenly throughout its triangular framework, allowing it to support heavy loads without internal columns. [1] Indeed, geodesic domes are notoriously difficult to heat and cool efficiently due to their vast, open volume and tendency to collect warm air at the top.

Which choice provides the most logical transition at the underlined portion [1] from the preceding sentence?

  1. A
    NO CHANGE
  2. B
    Consequently,
  3. However,Answer
  4. D
    Additionally,

Answer

The transition word 'However,' is the correct choice because it establishes a clear contrast between the structural benefits of geodesic domes and their thermal inefficiency.
The transition word 'However,' is correct because it properly signals the contrast between the positive structural characteristics of the geodesic dome and its negative energy efficiency attributes.

Step-by-Step Solution

1
Analyze the relationship between the first sentence (which highlights the geodesic dome's strength and structural efficiency) and the second sentence (which discusses its heating and cooling difficulties).
The relationship between the two sentences is one of contrast, as the second sentence introduces a major drawback.
Determining the logical connection is necessary to choose the correct transition type.
2
Evaluate the function of the transition in each option to see which one expresses contrast.
The option containing 'However,' is the only one that expresses contrast. The option containing 'NO CHANGE' (Indeed) expresses emphasis, 'Consequently,' expresses cause-and-effect, and 'Additionally,' expresses addition.
Matching the logical relationship of the transition to the relationship between the sentences is required to find the correct choice.
