46. The meteorologist had forecast rain,...........................Sheila brought her umbrella to work.
Answer: D
Sheila brought her umbrella to work because the meteorologist had forecast rain.
The use of "so" indicates a cause-and-effect relationship, where Sheila's action of bringing her umbrella is a direct consequence of the meteorologist's forecast of rain.
A) Nor
The word "nor" is used to present a negative condition and does not fit the context of a cause-and-effect relationship. It would imply an alternative negative situation, which is not relevant here.
B) Yet
"Yet" suggests a contrast or exception to a previously stated idea. It does not establish a logical connection between the forecast and Sheila's action, making it inappropriate for this context.
C) Because
While "because" does indicate a reason, it does not fit smoothly in the sentence structure as it would require a rephrasing to maintain grammatical correctness. Thus, it is not the best choice compared to "so."
D) So
"So" effectively conveys that Sheila's decision to bring her umbrella is a result of the weather forecast, making it the most suitable option. It clearly links the cause (the forecast of rain) to the effect (bringing the umbrella).
Conclusion
The correct answer is "so," as it appropriately connects the forecast of rain to Sheila's action of bringing her umbrella. All other options fail to establish the necessary causal relationship or do not fit grammatically within the sentence structure, reinforcing the clarity and coherence of the statement.
