d 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
