The second part of this question is missing the options. I've found it online. It is the following:
What inference about the Haida people’s life experiences can be drawn from the details in this story?
A. People would hunt and eat ravens when they were hungry.
B. People would drink sea water when they were thirsty.
C. People could not find drinkable water at the beach.
D. People often hid inside clam shells to escape hungry ravens.
Answer and Explanation:
First, we were asked to highlight details that reveal information about the environment where the Haida people lived. In the passage provided, we can highlight:
[...] there was no food on the large sandy beach, and the salt water just made them thirstier.
From these details, we gather information to answer the second question. We must choose the option that has the best inference about the Haida people's life experiences. We can clearly see they had a hard time surviving. Also:
C. People could not find drinkable water at the beach.
Because there was no drinkable water, the raven flew away to find the people provisions. No detail speaks of drinking the sea water, eating ravens, or hiding in the shell for protection from ravens. Therefore, letter C is certainly the best choice.
