When my dog died, jen, my best friend, mailed me a note of sympathy. in it she wrote that she knew how i felt because her cat had disappeared the summer before and never returned. the reason i adore jen is that she is such a caring person. a. kindness b. support c. worry d. understanding (sympathy is the underlined word.)

I think its understanding.

so you can understand and comprehend the meaning or the reasoning of the statement or the message

explanation:

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.
