25. Which of the following options best completes the sentence below? The responsibilities of a class president are extensive; ................., she should not become so involved that she neglects her studies.
Answer: B
However, she should not become so involved that she neglects her studies.
The phrase "however" appropriately indicates a contrast to the previous statement regarding the extensive responsibilities of a class president. It suggests that despite these responsibilities, there is an important limitation to be considered.
A) especially
The word "especially" would imply that the second part of the sentence is a specific instance of the first, which does not fit the context. The sentence is not providing an example or emphasizing a particular point; instead, it is presenting a contrasting idea.
B) however
"However" is the correct choice because it introduces a contrasting statement that highlights the necessity for balance. It emphasizes that while the responsibilities may be extensive, it is crucial that the class president does not let those responsibilities interfere with her academic obligations.
C) therefore
The use of "therefore" would suggest a conclusion or result stemming from the first part of the sentence. This does not work in this context, as the sentence is not concluding that neglecting studies is a result of having extensive responsibilities, but rather that it should be avoided.
D) indeed
"Indeed" would imply affirmation or agreement with the first statement, which is not the intent here. The second part of the sentence provides a cautionary note rather than reinforcing the ongoing responsibilities of the class president.
Conclusion
The choice "however" effectively captures the need for balance between the responsibilities of a class president and the importance of academic performance. All other options fail to convey this necessary contrast, which is critical to understanding the complete thought of the sentence.
