In 1916, two girls of wealthy families, best friends from Auburn, N.Y.—Dorothy Woodruff and Rosamond Underwood—traveled to a settlement in the Rocky Mountains to teach in a one-room schoolhouse ...

Why did they go then? Well, they wanted to do something useful. Soon, however, they realized what they had undertaken.

(Paragraph 3)They moved in with a local family, the Harrisons, and, like them, had little privacy, rare baths, and a blanket of snow on their quilt when they woke up in the morning. Some mornings, Rosamond and Dorothy would arrive at the schoolhouse to find the children weeping from the cold. In spring, the snow was replaced by mud over ice.

Q: What can we learn about the girls from paragraph 3?

They enjoyed much respect.

They had a room with a bathtub.

They lived with the local kids.

They suffered severe hardships.

细节理解题。根据第三段“They moved in with a local family, the Harrisons, and like them, had little privacy, rare baths, and a blanket of snow on their quilt when they woke up in the morning. (他们和一个当地家庭，哈里森一家一起搬进去，和他们一样，几乎没有隐私，很少洗澡，早上醒来时被子上覆盖着一层雪。)”以及“In spring, the snow was replaced by mud over ice. (在春天，雪被冰上的泥土所取代。)”可知，女孩们的生活条件非常艰苦，她们饱受磨难。故选D。
