Difficulty: MediumSentence-Level Transitions

The passage below is adapted from an article about twentieth-century astronomy.

In 1964, radio astronomers Arno Penzias and Robert Wilson detected a persistent, low-frequency hiss while testing a highly sensitive horn antenna. They initially blamed the static on nesting pigeons and painstakingly cleaned the instrument. <u>Consequently,</u> the mysterious signal remained, eventually leading to the discovery of cosmic microwave background radiation.

Which choice provides the most logical transition between the two sentences?

  1. A
    NO CHANGE
  2. Nevertheless,Answer
  3. C
    Furthermore,
  4. D
    Similarly,

Answer

The transition 'Nevertheless,' provides the correct logical relationship of contrast between the cleaning of the antenna and the signal's persistence.
The transition 'Nevertheless,' is correct because it logically connects the contrasting ideas: the antenna was cleaned, but the signal still remained.

Step-by-Step Solution

1
Analyze the relationship between the sentence before the transition and the sentence containing the transition.
The first sentence describes cleaning the antenna to remove noise, while the second sentence describes the noise remaining.
Determining the relationship between these two thoughts is the first step in selecting the correct transition.
2
Identify the logical category required.
Because the outcome (the signal remaining) is the opposite of what would be expected after cleaning the antenna, a contrast transition is needed.
Knowing the correct category helps eliminate transitions from incorrect categories (such as addition or cause-effect).
3
Evaluate the options to find the one that fits the contrast category.
The transition 'Nevertheless,' is the only option that expresses contrast.
This confirms the correct transition choice.
