There are those who claim that reductions in the spending on and deployment of weapons systems would result in a so-called “climate of peace,” thereby diminishing the likelihood of armed conflict. The facts show otherwise. These self-proclaimed pacifists are either the victims or the propagators of a false argument.

1.Which of the following is an assumption underlying the conclusion of the passage above?

A. Military actions involving our forces can be instigated by any number of different factors
B. Our buildup of weapons systems and combat personnel has prevented our adversaries from increasing their own spending on defense
C. The increased defense spending of the past 10 years has lessened the need for significant military expenditure in future decades
D. At the present time, state-of-the-art weapons systems and the augmentation of combat personnel are equally important to a nation’s defense
E. An established correlation between greater spending on weapons systems and a decreased incidence of conflict will persist

No actual black hole has yet been located or studied, but the concept has provided endless imaginative fodder for science fiction writers and endless theoretical fodder for physicists and astrophysicists.

Black holes are one of the more exotic theoretical manifestations of general relativity. The standard model for the formation of a black hole involves the collapse of a large star. For extremely massive stars that are four to five times the mass of our sun, the exclusion principle—the resistance between the molecular particles within the star as they are compressed—will not be strong enough to offset the gravity generated by the star’s own mass. The star’s increasing density will overwhelm the exclusion principle. What follows is runaway gravitational collapse. With no internal force to stop it, the star will simply continue to collapse in on itself, until it reaches a point of infinite density and zero volume, a phenomenon known as a singularity.

The star now disappears from the perceivable universe, like a cartoon character who jumps into a hole and pulls the hole in after him. What this process leaves behind is a different kind of hole—a profound disturbance in space time, a region where gravity is so intense that nothing, not even light, can escape from it. Any object falling within the boundary of a black hole will be sucked in and will disappear from our universe forever.

What would happen to an object, such as an astronaut, as it vanished into the black hole? Physicists have been amusing themselves with this question for years. Most believe that the astronaut would be destroyed by the intense gravitational forces within the black hole, or would explode in a flash of gamma rays as he or she approached the singularity at the hole’s core. Theoretically, an astronaut who managed to survive the passage would experience some very strange things, including acute time distortion, which would enable him or her to know, in a few brief seconds, the entire future of the universe in all its detail.
