Premise: Six months or so after getting a video recorder, many early buyers apparently lost interest in obtaining videos to watch on it.
Conclusion: But clearly, once the market for video recorders is saturated, businesses distributing videos face hard times.
Which of the following, if true, would most seriously weaken the conclusion above?
Assumption: The trend observed from early sale of video recorder will continue to be true in future.
Now any argument that finds the flaw in assumption will weaken the conclusion.
That's what D does by stating the fact that early buyers' behavior doesn't not represent that of masses.
Hope this help.
Some more from my side. Pls post explanations for the benefit of everyone.
1. The cost of transatlantic airfare has nearly doubled over the past five years, yet airlines are doing a booming business. Clearly, people today have more money to spend on vacations than they did five years ago.
All of the following, if true, would weaken the argument above EXCEPT:
(A) Most people buying transatlantic tickets today use them for business trips, so airfare is refunded by their companies.
(B) There are fewer airlines in existence today than five years ago.
(C) People are taking shorter vacations and staying in cheaper hotels than they used to.
(D) Crossing the Atlantic by ship requires more time than most people can afford.
(E) Domestic airline flights have seen a steady increase in passengers.
2. Archaeologists have recently found, in various grave sites in the Mexican state of Veracruz, small ceramic animals with attached wheels. At first, this find might seem to discredit the belief that the heel and its uses were unknown in pre-Colombian culture. On reflection, however, it would seem that the discovery actually bears out this belief. To be familiar with these toys and yet not to apply the principle of the wheel to daily tasks such as carting, transportation, and pottery making must indicate a lack of understanding of the wheel and its potential benefits.
Which of the following best expresses the argument made in the passage above?
(A) If the pre-Colombian people of Veracruz had understood the principle of the wheel, they would not have attached wheels to ceramic animals.
(B) If the pre-Colombian people of Veracruz had understood the principle of the wheel, they would have adapted it to everyday use.
(C) If the pre-Colombian people of Veracruz had uses for the wheel in their everyday lives, they would have adapted the idea of the wheel from the wheeled ceramic figures.
(d) The pre-Colombian people of Veracruz must have known of the wheel and its uses because they attached wheels to ceramic animals.
(E) Since the pre-Colombian people of Veracruz did not know of the wheel or its uses, the ceramic animals found in the grave sites must be the remains of later cultures.
3. The conflict between an artists work and the context in which it is placed is a traditional problem in aesthetics. Recent exhibits have given it a new urgency. Too often a painters canvases have been hung in an improper context because the gallery managers have not understood what the painter envisioned as the works proper environment.
As an attempt to solve the problem described above, it would be most reasonable to
(A) bring artists and gallery managers into closer contact, so as to increase the artists input into the way the exhibit is held
(B) provide brochures at the exhibit that describe the artist and how he or she intended the exhibit to look
(C) redesign galleries so that their dcor contains nothing that would distract the audience from the works themselves
(D) provide a uniform environment for all the works in an exhibition so that they appear within the same context
(E) instruct gallery managers in the fine points of aesthetic theory so that they will be able to tell what, if anything, a painting means
