Answer:
B. A line of people from all walks of life stood waiting for water.
C. The wind change drove smoke and ashes into the crowd.
D. The author’s husband made the man wait in line with everyone else.
Step-by-step explanation:
The given passage is from the short personal narrative of Emma M. Burke about her experience during the 1906 earthquake in San Francisco. This narrative is just a general idea of how devastating the disaster was, which is not comprehensible in words.
In the given passage, the speaker/ narrator explains how the dusty and hot winds brought so much ash and pain to the people. Everyone, be it "Americans, Japanese, Negroes, Chinese and all sorts and degrees of men, women, and children" were lined up for cold water. And despite everyone's eagerness to get their hands on the cold water, the author's husband made the man wait in line like everyone else, for they are all in the same situation and must abide by the rules.
Thus, the key events that happen in this passage are options B, C, and D.
