Which inference about rivers is supported by the passages? 01. Rivers are an unreliable source of drinking water. 2. Rivers are critical in sustaining the economies of an area. 3. Rivers are essential to transport cargo across the country. 4. Rivers begin above sea level and empty into the Gulf of Mexico.

is that the whole question?

i guess you are missing the idea that has to be supported, am i right?

the purpose of the heading in the passage is to identify who is telling the story.

this excerpt is part of the book sugar changed the world (2010) written by marc aronson and marina budhos. as the book has been written by two people, the heading "marc" indicates that this specific excerpt is being narrated by aronson. in the fragment, marc describes his grandfather's story after hearing it from his cousin. however, there are other excerpts where budhos is the one that tells the story of her family.

aronson and budhos, who are husband and wife in real life, decided to write sugar changed the world when they found out how sugar, which had an important role in slavery and economy, changed their ancestors' lives.

there is no short story here so that i can answer the question.
