Grockit RC !!

Numerous and varied are the objections that have
been advanced against the theory of selection since it
was first enunciated by Darwin and Wallace-from the
unreasoning strictures of Richard Owen and the acute and
(5) thoughtful criticisms of Albert Wigand and Nägeli to
the opposition of our own day, which contends that
selection cannot create but only reject, and which fails
to see that precisely through this rejection its
creative efficacy is asserted.
(10) The champions of this view are for discovering the
motive forces of evolution in the laws that govern
organisms-as if the norm according to which an event
happens were the event itself, as if the rails which
determine the direction of a train could supplant the
(15) locomotive. Of course, from every form of life there
proceeds only a definite, though extremely large, number
of tracks, the possible variations, whilst between them
lie stretches without tracks, the impossible variations,
on which locomotion is impossible. But the actual
(20) traveling of a track is not performed by the track, but
by the locomotive, and on the other hand, the choice of
a track, the decision whether the destination of the
train shall be Berlin or Paris, is not made by the
locomotive, the cause of the variation, but by the
(25) driver of the locomotive, who directs the engine on the
right track.
In the theory of selection the engine driver is
represented by utility, for with utility rests the
decision as to what particular variational track shall
(30) be traveled. The cogency, the irresistible cogency, of
the principle of selection is precisely its capacity of
explaining why fit structures always arise, and that
certainly is the great problem of life. Not the fact of
change, but the manner of the change, whereby all things
(35) are maintained capable of life and existence, is the
pressing question.

The author's tone in the passage is:
A. Impolitic
B. Vehement
C. Satirical
D. Expository
E. Obscurring

This passage can best be described as:

An extended metaphor linking natural selection and locomotive travel

A figurative rejection of one interpretation of Darwinian theory

An attempt to defend a theory of natural selection in rhetorical terms

An impassioned argument against detractors of natural selection

A defense of an evolutionary theory in light of certain challenges


The author of the passage is most likely:

A contemporary and friend of Charles Darwin

An engineer comparing railroad technology to nature

A zoologist advancing a modified theory of evolution

A modern scholar rejecting the notion of natural selection

A historian contrasting two sides of a scientific debate



I jst did not get this passage.. Just cudnt...
This one is from Grockit.. I was not aware of the meaning of the words for first question..

OK. here is my understanding:
first paragraph: several objections against selection theory, objections-> earlier and modern;

modern objections state that the theory does not something, but something else. and they failed to understand that this particular something else is important in the theory.

second paragraph: this paragraph tries to annul the objections by comparing railway system to the theory, i.e to the theory's construction.

1) D;
2) E: evolutionary theory is the theory of selection per se;
3) C: not A because the author say our own day when he began considering the objections ranging from that of Owen to that of our own day.
B=> no comparison of railroad to nature, but comparison between railroad and the theory's structure.
Not D, because he/she is not rejecting the theory.
as for E, there is no debate, but criticism
I know of no more encouraging fact than the unquestionable ability of a man to elevate his life by conscious endeavor.
