Difficulty: MediumSentence-Level Transitions

In 1965, chemist Stephanie Kwolek was analyzing a liquid crystalline polymer solution when she noticed it had a low viscosity and a cloudy, watery appearance. Most researchers would have discarded such a mixture as a failed experiment. [1] Consequently, Kwolek insisted on spinning the solution in a laboratory spinneret to test its properties. The resulting fibers possessed an unprecedented strength-to-weight ratio, eventually leading to the development of Kevlar.

Which choice best replaces the underlined portion [1] to create a logical transition between the sentences?

  1. A
    NO CHANGE
  2. Instead,Answer
  3. C
    Likewise,
  4. D
    Furthermore,

Answer

The correct transition is 'Instead,' because it establishes a contrast between Kwolek's actions and the typical behavior of other researchers.
The transition 'Instead,' correctly establishes the contrast between the typical reaction of researchers (discarding the cloudy solution) and Kwolek's contrasting action (testing it).

Step-by-Step Solution

1
Analyze the relationship between the preceding sentence and the sentence containing the transition.
The preceding sentence describes how other researchers would discard the cloudy solution. The sentence with the transition describes Kwolek insisting on testing it.
To identify the type of logical connection required between the two thoughts.
2
Determine the correct transition category.
Kwolek's decision to test the solution is in direct contrast to what other researchers would do (discarding it), meaning a contrast transition is needed.
To narrow down the correct transition category.
3
Evaluate the choices to find the transition that correctly indicates contrast.
'Instead,' is a contrast transition. The other options express cause-and-effect, similarity, or addition.
To select the option that correctly conveys the logical flow.
