Difficulty: EasySentence-Level Transitions

In 1968, researcher Spencer Silver was working at 3M to develop a super-strong adhesive for the aerospace industry. Instead, he accidentally created a very weak glue that stuck lightly to surfaces, could be easily peeled off, and left no residue behind.

Which choice provides the most logical transition at the underlined portion?

  1. NO CHANGEAnswer
  2. B
    Furthermore,
  3. C
    Therefore,
  4. D
    For instance,

Answer

The transition that indicates contrast ('Instead') is correct because the second sentence describes an unexpected, opposite result to the goal mentioned in the first sentence.
The correct transition is 'Instead' because it accurately communicates a contrast. The writer contrasts Spencer Silver's goal of developing a strong adhesive with his accidental creation of a weak glue.

Step-by-Step Solution

1
Analyze the relationship between the first sentence and the second sentence.
The first sentence describes the goal (creating a super-strong adhesive), while the second sentence describes the actual, contrasting result (creating a very weak glue).
Transitions must reflect the logical connection between the clauses they connect.
2
Evaluate the transition category needed.
Since the outcome is the opposite of the intended goal, a contrast transition is required.
Contrast transitions like 'instead' or 'however' signal that the second statement contradicts or qualifies the first.
3
Compare the choices to identify the correct transition.
Only 'Instead' establishes a contrast relationship, while the other options indicate addition, cause-effect, or illustration.
Choosing the transition that matches the logical relationship ensures sentence-level cohesion.
