As a result, none of them conveyed a valid right to drill.

Let us at least protect what is within it. The many roadless areas within the monument should remain so—protected as wilderness. The monument’s designation means little if a pattern of exploitation is allowed to continue.Environmentalists—including the Southern Utah Wilderness Alliance, the Natural Resources Defense Council, and the Wilderness Society—appealed BLM’s decision to the Interior Department’s Board of Land Appeals.

From Steven Jay Gould: “The Panda’s Thumb”
… The message is paradoxical BUT profound. Orchids manufacture
their intricate devices from the common components of ordinary flowers, parts usually fitted for very different
functions. If God had designed a beautiful
machine to reflect his wisdom and power, surely he would not have used a collection of parts generally
fashioned for other purposes. Orchids were not made by an ideal engineer; they are jury-rigged
from a limited set of available components.
Thus, they must have evolved from ordinary flowers.
Thus the paradox and the common theme of this trilogy of essays: Our textbooks
like to illustrate evolution with examples of optimal design—nearly perfect mimicry of a dead leaf
by a butterfly or of a poisonous
species by a palatable relative. However,
ideal design is a lousy argument
for evolution, for it mimics the
postulated action of an omnipotent creator. Odd arrangements and funny
solutions are the proof of
evolution—paths that a sensible God would never tread but that a natural
process, constrained by history, follows perforce.

Q16. This passage is by John Russell:
“There never was a painter like Thomas Eakins, who was born in 1844, died in 1916…. It is not simply that in his hands painting became an exact science, so that if he paints two men rowing on a river, we can tell the month, day, and the hour that they passed UNDER a certain bridge. We admire Eakins for that, but we prize him above all for the new dimension of moral awareness that he brought to American painting.”

Q20. From an advertisement for Equal Exchange Coffee (1997):
It may be a little early in the morning to bring this up, but if you buy coffee from large corporations, you are inadvertently maintaining the system which keeps small farmers poor while lining the pockets of rich corporations. By choosing Equal Exchange coffee, you CAN help to make a change. We believe in trading directly with small farming cooperatives at mutually agreed-upon prices with a fixed minimum rate. Then, should the coffee market decline, the farmers are still guaranteed a fair price. So have a cup of Equal Exchange Coffee and make a small farmer happy. Of course, your decision to buy Equal Exchange need not be completely altruistic. For we take as much pride in refining the taste of our gourmet coffees as we do in helping the farmers who produce them….

Q21. This passage is by Paul Davies:
“There is little on the Moon to sustain human life. Mars, however, is a different story. Because of the planet’s relatively benign environment, it is theoretically able to support a permanent human presence. If provided with the right equipment, astronauts would have SOME chance of living there for years. A one-way trip to Mars need not mean a quick demise.”
[expand title=View Answer]D = a discounting term[/expand]
Q22. By Ben Selznik:
“The drinking age is not set by the federal government; it is set by the
states. Currently, each state has its law set at 21. However, this figure neither necessarily reflects research and
careful consideration nor appeals to constituents. Instead, it reflects the
fact that drinking age became tied to highway funds somewhere along the way.
Because of this, were a state to lower their drinking age, they would also have
to significantly raise taxes to offset the lost highway funds from the
government. This hand-tying is asinine. if the drinking age is a state DECISION, it should be made by states independently
of funds for highways. Before any progress can be made, lawmakers must sever
this illogical connection.”

Q23. This passage is by
Paul Davies:
“OBVIOUSLY this strategy carries significant risks in
addition to those faced by a conventional Mars mission. Major equipment failure
could leave the colony without enough power, oxygen or food. An accident might
kill or disable an astronaut who provided some vital expertise. A supply drop
might fail, condemning the colonists to starve in a very public way. Even if
nothing went wrong, the astronauts’ lives would certainly be shortened by the
harsh conditions….”

Q25. By Ben Selznik:
“A fair portion of drinkers between the ages of 18 and 21 are at colleges where alcohol can be easily obtained.… [C]olleges know full well that underage drinking exists. Students know that they are drinking underage and therefore illegally. And yet, the game continues with colleges trying to make sure that no alcohol-related tragedies occur. This game isn’t the fault of colleges, nor is it the fault of students. Instead, it is the fault of our law, which classifies part of this college-age set as “underage” and the rest as “of age.” When it comes to colleges, our law OBVIOUSLY doesn’t reflect reality. It must therefore be changed.”
