Altruism and study of meerkats

Both reading and listening passages are about altruism, human or animal perform selfishness actions that are beneficial for others.

First, according to the reading passage, meerkats are a perfect instance of performing altruistic actions. In a group often one individual acts as a guard, looking for predators, while others are hunting for food. They put themselves in risk for others' interests. However, the professor refutes this claim, asserting that individual acts as a sentinel only with a full stomach.

Secondly, in the reading passage, it is stated that the sentinel meerkat gives alarm in order to alert others about danger, so they can seek for shelter. Notwithstanding, this point is challenged by the professor. She claims that often the sentinel stand near the burrow, therefore they can hide faster from predators.

Finally, the article establishes that organ donors receive nothing for their help. However, the professor argues that people, who were the donors gain recognition in the society and approval from their surroundings.
