Difficulty: MediumSentence-Level Transitions

Passage

In 19471947, computer pioneer Grace Hopper recorded the first computer "bug" when she found a moth trapped in a relay of the Harvard Mark II. [1] Consequently, her most significant contribution to computer science was the invention of the compiler, a program that translated written English commands into machine code.

Which choice provides the most logical transition from the preceding sentence?

  1. A
    NO CHANGE
  2. However,Answer
  3. C
    Moreover,
  4. D
    For example,

Answer

However,
The correct option uses the transition 'However,' which establishes a contrast between the first sentence (a famous, lighthearted anecdote about finding a moth) and the second sentence (which describes her most significant and serious technical contribution, the compiler).

Step-by-Step Solution

1
Analyze the relationship between the two sentences.
The first sentence describes a famous but minor historical anecdote (Grace Hopper finding a moth in a computer relay). The second sentence describes her most significant technical achievement (inventing the compiler).
Understanding the context and logical connection is necessary to choose the correct transition.
2
Evaluate the relationship type.
The transition needs to signal a shift or contrast between a minor, humorous event and a major, serious breakthrough.
This helps narrow down the category of transition words to search for (contrast).
3
Test the available options against this relationship.
'However' fits the contrast relationship perfectly. 'Consequently' (cause-effect), 'Moreover' (addition), and 'For example' (illustration) do not fit.
Selecting the option that correctly represents the contrast relationship ensures logical cohesion in the passage.
