Responding to objections and alternative speculations (a feature of cause and effect writing), Terbor writes, “Many would argue that examples of altruism are all around us, and that these examples are motivated by our empathetic feelings toward others” (par. 4) but then he goes on to point out that the study he conducted “does suggest that even acts that seem altruistic may be motivated by egoism” (par. 12). List other moments in the essay where Terbor handles objections and alternative speculations in a fair and balanced way. How does Terbor concede and refute these other possibilities?
