Question 10 - ELAR: Reading Practice Test for the TSIA2

The main idea of the attached passage is ____.

Many past studies may have overestimated human generosity, if a new piece of research is any clue.

The study recreated a game often used in laboratory experiments to assess people’s willingness to give away money, or their altruism.

Participants are typically granted anonymity. But the new study was designed to afford an assurance of anonymity even more believable than usual. It was set up so that participants would be unaware any experiment was even happening – or that any decision would even be counted, let alone watched.

Under this seemingly greater level of secrecy, the level of giving plunged to zero.
