NO.5-2-2
Initially the Vinaver theory that Malory’s eight
romances, once thought to be fundamentally unified.
were in fact eight independent works produced both a
sense of relief and an unpleasant shock. Vinaver’s the-
ory comfortably explained away the apparent contra-
dictions of chronology and made each romance inde-
pendently satisfying. It was, however, disagreeable to
find that what had been thought of as one book was
now eight books. Part of this response was the natural
reaction to the disturbance of set ideas. Nevertheless,
even now, after lengthy consideration of the theory’s
refined but legitimate observations, one cannot avoid
the conclusion that the eight romances are only one
work. It is not quite a matter of disagreeing with the
theory of independence, but of rejecting its implica-
tions: that the romances may be taken in any or no
particular order, that they have no cumulative effect,
and that they are as separate as the works of a modern
novelist.
17. The primary purpose of the passage is to
(A) discuss the validity of a hypothesis
(B) summarize a system of general principles
(C) propose guidelines for future argument
(D) stipulate conditions for acceptance of an
interpretation
(E) deny accusations about an apparent
contradiction
18. It can be inferred from the passage that the author
believes which of the following about Malory’s
works?
I. There are meaningful links between and
among the romances.
II. The subtleties of the romances are obscured
when they are taken as one work.
III. Any contradictions in chronology among the
romances are less important than their over-
all unity.
(A) I only (B) III only
(C) I and III only (D) II and III only
(E) I, II, and III
19. The author of the passage concedes which of the
following about the Vinaver theory?
(A) It gives a clearer understanding of the unity of
Malory’s romances.
(B) It demonstrates the irrationality of considering
Malory’s romances to be unified.
(C) It establishes acceptable links between Malory’s
romances and modern novels.
(D) It unifies earlier and later theories concerning
the chronology of Malory’s romances.
(E) It makes valid and subtle comments about
Malory’s romances.
20. It can be inferred from the passage that, in evaluating
the Vinaver theory, some critics were
(A) frequently misled by the inconsistencies in
Malory’s work
(B) initially biased by previous interpretations of
Malory’s work
(C) conceptually displeased by the general
interpretation that Vinaver rejected
(D) generally in agreement with Vinaver’s
comparisons between Malory and modern
novelists
(E) originally skeptical about Vinaver’s early
conclusions with respect to modern novels
We can distinguish three different realms of matter,
three levels on the quantum ladder. The first is the
atomic realm, which includes the world of atoms, their
interactions, and the structures that are formed by them,
such as molecules, liquids and solids, and gases and plas-
mas. This realm includes all the phenomena of atomic
physics, chemistry, and, in a certain sense, biology. The
energy exchanges taking place in this realm are of a rela-
tively low order. If these exchanges are below one elec-
tron volt, such as in the collisions between molecules of
the air in a room, then atoms and molecules can be
regarded as elementary particles. That is, they have
“conditional elementarity” because they keep their iden-
tity and do not change in any collisions or in other pro-
cesses at these low energy exchanges. If one goes to
higher energy exchanges, say 104 electron volts, then
atoms and molecules will decompose into nuclei and
electrons; at this level, the latter particles must be consi-
dered as elementary. We find examples of structures and
processes of this first rung of the quantum ladder on
Earth, on planets, and on the surfaces of stars.
The next rung is the nuclear realm. Here the energy
exchanges are much higher, on the order of millions of
electron volts. As long as we are dealing with phenom-
ena in the atomic realm, such amounts of energy are
unavailable, and most nuclei are inert: they do not
change. However, if one applies energies of millions of
electron volts, nuclear reactions, fission and fusion, and
the processes of radioactivity occur; our elementary par-
ticles then are protons, neutrons, and electrons. In addi-
tion, nuclear processes produce neutrinos, particles that
have no detectable mass or charge. In the universe, ener-
gies at this level are available in the centers of stars and
in star explosions. Indeed, the energy radiated by the
stars is produced by nuclear reactions. The natural
radioactivity we find on Earth is the long-lived remnant
of the time when now-earthly matter was expelled into
space by a major stellar explosion.
The third rung of the quantum ladder is the subnu-
clear realm. Here we are dealing with energy exchangers
of many billions of electron volts. We encounter excited
nucleons, new types of particles such as mesons, heavy
electrons, quarks, and gluons, and also antimatter in
large quantities. The gluons are the quanta, or smallest
units, of the force (the strong force) that keeps the
quarks together. As long as we are dealing with the
atomic or nuclear realm, these new types of particles do
not occur and the nucleons remain inert. But at subnu-
clear energy levels, the nucleons and mesons appear to
be composed of quarks, so that the quarks and gluons
figure as elementary particles.
21. the primary topic of the passage is which of the
following?
(A) The interaction of the realms on the quantum
ladder
(B) Atomic structures found on Earth, on other
planets, and on the surfaces of stars
(C) Levels of energy that are released in nuclear
reactions on Earth and in stars
(D) Particles and processes found in the atomic,
nuclear, and subnuclear realms
(E) New types of particles occurring in the atomic
realm
22. According to the passage, radioactivity that occurs
naturally on Earth is the result of
(A) the production of particles that have no
detectable mass or electric charge
(B) high energy exchanges on the nuclear level that
occurred in an ancient explosion in a star
(C) processes that occur in the center of the Sun,
which emits radiation to the Earth
(D) phenomena in the atomic realm that cause
atoms and molecules to decompose into
nuclei and electrons
(E) high-voltage discharges of electricity that took
place in the atmosphere of the Earth shortly
after the Earth was formed
23. The author organizes the passage by
(A) making distinctions between two groups of par-
ticles, those that are elementary and those
that are composite
(B) explaining three methods of transferring energy
to atoms and to the smaller particles that
constitute atoms
(C) describing several levels of processes, increasing
in energy, and corresponding sets of particles,
generally decreasing in size
(D) putting forth an argument concerning energy
levels and then conceding that several qualifi-
cations of that argument are necessary
(E) making several successive refinements of a defi-
nition of elementarity on the basis of several
groups of experimental results
24. According to the passage, which of the following
can be found in the atomic realm?
(A) More than one level of energy exchange
(B) Exactly one elementary particle
(C) Exactly three kinds of atomic structures
(D) Three levels on the quantum ladder
(E) No particles smaller than atoms
25. According to the author, gluons are not
(A) considered to be detectable
(B) produced in nuclear reactions
(C) encountered in subnuclear energy exchanges
(D) related to the strong force
(E) found to be conditionally elementary
26. At a higher energy level than the subnuclear level
described, if such a higher level exists, it can be
expected on the basis of the information in the pas-
sage that there would probably be
(A) excited nucleons (B) elementary mesons
(C) a kind of particle without detectable mass or
charge
(D) exchanges of energy on the order of millions of
electron volts
(E) another set of elementary particles
27. The passage speaks of particles as having

exchange

(C) are mathematically simpler than some other set of
particles
(D) release energy at a low level in collisions
(E) belong to the nuclear level on the quantum
