　　Passage 3

　　A decrease in face-to-face social contact can precipitate depression. Time spent using the Internet cannot be spent in face-to-face social contact, so psychologists have speculated that sharply increasing Internet use can cause depression. Studies of regular Internet users have found a significantly higher incidence of depression among those who had recently doubled the amount of time they spent using the Internet than among those whose use had not increased. Hence, the psychologists’ speculation is correct.

　　Which of the following is an assumption on which the argument depends?

　　A. In general, the reason that the people in the studies had doubled their Internet use was not that they had earlier experienced a significant decrease in opportunities for face-to-face social contact.

　　B. A sharp decrease in face-to-face social contact is the only change in daily activity that can lead to an increased incidence of depression.

　　C. Using the Internet presents no opportunities for people to increase the amount of face-to-face social contact they experienced in their daily lives.

　　D. Regular Internet users who are depressed will experience an immediate improvement in mood if they sharply decrease the amount of time they spend on the Internet.

　　E. Before they doubled the time they spent on the Internet, the people who did so were already more prone to depression than are regular Internet users in general.

　　Passage 9

　　An Irish newspaper editorial encouraging women to participate in the non-importation movement launched in Ireland in 1779 appears consistent with a perception that the political use of the consumer boycott originated in North America and spread eastwards across the Atlantic to Ireland. This is a view that most historians have concurred with. For example, T.H. Breen argued that the consumer boycott was a brilliantly original American invention. Breen did acknowledge that a few isolated boycotts may have taken place in other countries. However, Mary ODowd argues that from the late seventeenth century, Irish political discourse advocated for the nonconsumption of imported goods and support for home manufactures by women in ways that were strikingly similar to those used later in North America.
