The listening set is totally against the idea claimed in the reading passage that altruism is selfless from end to end.

The professor in the listening passage believes that altruism is a method of taking others' advantages.

First, in the meerkat case, it is said that the sentinels sacrifice themselves both in foods and lives. And in this way, the meerkat is an example of altruism. But, it is also shown that the sentinel-meerkats go fill their stomach firstly and take good position in a life run when a predator is coming. Moreover, the action of the others may decrease the attention which is put on the sentinel. Therefore, the professor in the listening passage contradicts the previous point in details that omitted in the reading passage.

Second, when somebody donates a kidney of himself in the reading passage among human donations, it is general ly considered selfless because this kind of sacrifice will receive little benefits and can be regarded as an instance of altruism. However, the thesis in the listening passage which is supported by reasons states that human donations can't be that way. I t gains praise and good social opportunities and approvals for the donators, that is to say, donations are not quite selflessness.

Generally speaking, the professor in the listening set of passage hold s distinct point from the reading passage, which goes that neither the meerkat case nor human donations case can be an example of altruism.
