Passage
NATURAL SCIENCE: This passage discusses some of the controversy surrounding the existence of dark matter in the universe.
Dark matter in the universe is believed by some
scientists to be a substance that is not readily observable
because it does not directly refract light or energy. Its
existence can only be deduced because of the effect that
(5) it has on surrounding matter. In fact, some members of
the scientific community have argued that dark mat-
ter does not actually exist. Others, however, believe in
its existence, in part because the scientific community
does not have a complete understanding of gravita-
(10) tional science. On the other hand, some would argue
that it is the understanding of gravitational science that
leads most scientists to believe in the existence of dark
matter, because without dark matter, there are many
cosmological phenomena that are difficult to explain.
(15) For example, dark matter in the universe may
have a peculiar effect on the Milky Way galaxy. Some
scientists believe that the interaction between dark mat-
ter and other smaller, nearby galaxies is causing the
Milky Way galaxy to take on a warped profile. It has
(20) been asserted that not only does dark matter exist, it
may also be responsible for the Milky Way’s unusual
shape. The interaction referenced involves two smaller
galaxies near the Milky Way, called Magellanic clouds,
moving through an enormous amount of dark matter,
(25) which, in effect, enhances the gravitational pull that the
two Magellanic clouds could have on the Milky Way
and other surrounding bodies. Without the existence of
the dark matter, the Magellanic clouds would not have
sufficient mass to have such a strong effect on the bend
(30) of the Milky Way galaxy.
The strongest evidence for the validity of this
hypothesis rests in Newtonian physics, and the hypoth-
esis that anything with mass will exert a gravitational
pull. The Milky Way and other galaxies with pecu-
(35) liar warped shapes are being molded by a gravitational
force. However, there is nothing readily observable
with sufficient mass that could cause such a high level
of distortion via gravitational pull in the vicinity of
the Milky Way. Therefore, something that is not easily
(40) observed must be exerting the necessary force to create
the warped shape of the galaxy.
Aaron Romanowsky and several colleagues have
questioned the effect that dark matter might have on
galaxies. They point to the existence of several ellipti-
(45) cal galaxies surrounded by very little dark matter as
evidence that dark matter is not, in fact, the cause
of the warped galaxies. While they do not claim that
their findings should be interpreted to conclude that
dark matter does not exist, they apparently believe
(50) that the results of their studies cast doubt on some
of the conventional theories of galaxy formation and
manipulation.
Several models constructed by researchers from
the University of California at Berkeley, however,
(55) point to the idea that dark matter is the most likely
explanation for the distorted shape of the Milky Way
and other galaxies. Using computer models, they have
mapped the likely interactions between certain galax-
ies and the surrounding dark matter, and those models
(60) have shown not only the possibility that dark matter
is responsible for the warped shape of the Milky Way,
but that the relationship between the dark matter and
the Magellanic clouds is dynamic; the movement of
the clouds through the dark matter seems to create a
(65) wake that enhances their gravitational influence on the
Milky Way.

Q. Which one of the following is NOT mentioned in the passage as a scientific theory regarding dark matter?
- a)The existence of dark matter cannot be proved by direct observation.
- b)Dark matter may be responsible for the shape of the Milky Way.
- c)It is certain that dark matter has no influence on surrounding celestial bodies.
- d)Magellanic clouds require the presence of dark matter in order to influence the shape of galaxies.
Correct answer is option 'C'. Can you explain this answer?

There is nothing in the passage to indicate with certainty that dark matter has no influence on surrounding celestial bodies. Although Aaron Romanowsky suggests that dark matter is not responsible for warped galaxies, there is no discussion in the passage to show that he believes dark matter has no influence whatsoever on galaxy shape or other cosmological phenomena. The other answer choices are all mentioned in the passage as scientific theories regarding dark matter.

Itsexistence can only be deduced because of the effect that(5) it has on surrounding matter. In fact, some members ofthe scientific community have argued that dark mat-ter does not actually exist. Others, however, believe inits existence, in part because the scientific communitydoes not have a complete understanding of gravita-(10) tional science. On the other hand, some would arguethat it is the understanding of gravitational science thatleads most scientists to believe in the existence of darkmatter, because without dark matter, there are manycosmological phenomena that are difficult to explain.(15) For example, dark matter in the universe mayhave a peculiar effect on the Milky Way galaxy. Somescientists believe that the interaction between dark mat-ter and other smaller, nearby galaxies is causing theMilky Way galaxy to take on a warped profile. It has(20) been asserted that not only does dark matter exist, itmay also be responsible for the Milky Way’s unusualshape. The interaction referenced involves two smallergalaxies near the Milky Way, called Magellanic clouds,moving through an enormous amount of dark matter,(25) which, in effect, enhances the gravitational pull that thetwo Magellanic clouds could have on the Milky Wayand other surrounding bodies. Without the existence ofthe dark matter, the Magellanic clouds would not havesufficient mass to have such a strong effect on the bend(30) of the Milky Way galaxy.The strongest evidence for the validity of thishypothesis rests in Newtonian physics, and the hypoth-esis that anything with mass will exert a gravitationalpull. The Milky Way and other galaxies with pecu-(35) liar warped shapes are being molded by a gravitationalforce. However, there is nothing readily observablewith sufficient mass that could cause such a high levelof distortion via gravitational pull in the vicinity ofthe Milky Way. Therefore, something that is not easily(40) observed must be exerting the necessary force to createthe warped shape of the galaxy.Aaron Romanowsky and several colleagues havequestioned the effect that dark matter might have ongalaxies. They point to the existence of several ellipti-(45) cal galaxies surrounded by very little dark matter asevidence that dark matter is not, in fact, the causeof the warped galaxies. While they do not claim thattheir findings should be interpreted to conclude thatdark matter does not exist, they apparently believe(50) that the results of their studies cast doubt on someof the conventional theories of galaxy formation andmanipulation.Several models constructed by researchers fromthe University of California at Berkeley, however,(55) point to the idea that dark matter is the most likelyexplanation for the distorted shape of the Milky Wayand other galaxies. Using computer models, they havemapped the likely interactions between certain galax-ies and the surrounding dark matter, and those models(60) have shown not only the possibility that dark matteris responsible for the warped shape of the Milky Way,but that the relationship between the dark matter andthe Magellanic clouds is dynamic; the movement ofthe clouds through the dark matter seems to create a(65) wake that enhances their gravitational influence on theMilky Way.Q.Which one of the following is NOT mentioned in the passage as a scientific theory regarding dark matter?a)The existence of dark matter cannot be proved by direct observation.b)Dark matter may be responsible for the shape of the Milky Way.c)It is certain that dark matter has no influence on surrounding celestial bodies.d)Magellanic clouds require the presence of dark matter in order to influence the shape of galaxies.Correct answer is option 'C'.
