　　8.Scientist：More than 1, 000 large asteroids regularly cross the Earth's path．Even though the probabil- ity of one colliding with the Earth is extremely slight, we should do whatever we can to reduce that probability since any such collision would be catastrophic．The best way to avoid such a disaster is to deflect the asteroids．The only known way of deflecting asteroids is by hitting them with nuclear weapons that would be stored in space stations．

　　The scientist's claims are structured so as to lead to which of the following conclusions？

　　(A)Nuclear technology is the only technology that can plausibly be used to prevent natural catastrophes．

　　(B)Nuclear weapons should be deployed in space．

　　(C)No catastrophe has yet been caused by the collision of an asteroid with the Earth．

　　(D)The 1, 000 large asteroids that cross the Earth's path pose only an extremely slight risk of colliding with the Earth．

　　(E)There is currently no acceptable use to which nuclear weapons can be put, aside from pro- tecting the Earth from asteroids．

　　9.It has long been thought that high levels of the hor- mone testosterone contribute to the onset of heart disease in men．However, this view cannot be correct, since men who have heart disease typically show significantly lower levels of testosterone than do men who have not had heart disease．

　　The argument above assumes which of the following？

　　(A)Many men who have never had heart disease have unusually low levels of testosterone．

　　(B)Having heart disease does not significantly lower the level of testosterone in men．

　　(C)Levels of hormones other than testosterone significantly affect the likelihood that a man will develop heart disease．

　　(D)Heart disease and lowered testosterone levels in men are the effects of a single common cause．

　　(E)High levels of testosterone have never been thought to contribute to a serious disease other than heart disease

　　10.The time-out technique involves removing the child from an undesirable situation in order to let the child think things over．Over the last two decades, family doctors have been advocating this technique as preferable to spanking, which is now known to be potentially injurious and no more effective．

　　10.Which of the following can properly be concluded from the data presented in the graph？

　　(A)The 1962 survey was based on a larger sample than the 1992 survey was．

　　(B)In the period between the surveys, denying tele- vision privileges was never the disciplinary technique most popular with parents．

　　(C)The four disciplinary techniques featured in the graph were the only disciplinary techniques named by parents in either survey．

　　(D)The 1962 survey allowed parents to name more than one disciplinary technique, but the 1992 survey may not have allowed this．

　　(E)In the period between the surveys, there were no significant changes in the popularity of lec- turing children as a disciplinary method．
