4. According to the passage, Margaret and others at Naxos generally regard Helga as

Answer: D

Explanation:

Margaret and others at Naxos generally regard Helga as somewhat intimidating.

Helga is perceived as somewhat intimidating by Margaret and the other faculty members at Naxos. This is indicated by Margaret's cautious demeanor and her admission that "nearly everyone was" afraid of Helga, suggesting a level of respect mixed with apprehension.

A) highly reliable

This option is incorrect because there is no indication in the passage that Helga is regarded as reliable. In fact, her indifference towards attending her classes and her decision to leave Naxos suggest a lack of dependability in her role as a teacher.

B) unusually friendly

This option is also incorrect. The passage highlights Helga's aloofness and lack of engagement with others, as seen in her dismissal of Margaret's offer for help and her general disinterest in interactions, which does not align with being described as friendly.

C) relatively practical

This option is not accurate. Helga's actions and thoughts reveal a sense of dissatisfaction with her situation rather than practicality. Her decision to not attend class and her disdain for the food served at Naxos reflect a more emotional and subjective perspective than a practical one.

D) somewhat intimidating

This option is correct. The passage explicitly states that "nearly everyone was" afraid of Helga, indicating that her presence and demeanor are intimidating to others. Margaret’s hesitance to press Helga with questions further underscores this perception.

Conclusion

The correct answer is that Helga is regarded as somewhat intimidating, which is supported by the text's portrayal of her as someone who discourages inquiries and instills fear in her colleagues. Other options fail because they do not align with the descriptions or sentiments expressed by Margaret and others at Naxos towards Helga.
