Researchers have developed a technology that uses sound as a means of converting heat into electrical energy. Converters based on this technology can be manufactured small enough to be integrated into consumer electronics, where they will absorb significant quantities of heat. A group of engineers is now designing converters to be sold to laptop computer manufacturers, who are expected to use the electrical output of the converters to conserve battery power in their computers.
new tech -> sound as a means of converting heat -> electrical energy
this tech = small enough -> integrated into consumer electronics and absorbs heat from CE.
new tech -> to be sold to laptop computer manufacturers who use the electrical output to conserve battery.
Where is the conclusion? Which of the following would, if true, provide the strongest evidence that the engineers' plan will be commercially successful for their group? <—
It is here.Quote:
A) The sound that is used by the converters is generated by the converters themselves.
This only talks about the converter itself. (A) is out.
Quote:
B) Most laptop computer manufacturers today receive fewer complaints than in previous years regarding shortness of operating time on a single battery charge.
This is why the manufactures need to improve the laptop batteries. But how are they going to improve? (B) is out.
Quote:
C) The overheating of microprocessors in laptop computers presents a major technological challenge that manufacturers are prepared to meet at significant expense.
TBH, i missed this answer at first by overlooking "manufacturers"—
fast reading is more harmful than helpful. I thought this answer was talking about the engineer's challenge. However, this actually contributes to the problem that the manufactures face when they produce laptop computers. This problem, in turn, is solved by the converters absorbing heat from the laptop. The converters then convert heat to energy. Ultimately, the laptop computer reuse this energy. Hence, conserving battery.
Quote:
D) Although battery technology has improved significantly, the average capacity of laptop computer batteries has not.
The reasoning is only concerned whether the converters will solve the manufactures' problem. This does not solve anything. (D) is out.
Quote:
E) Electrical power generated by the converters can be used to power the fans installed to cool computers' components.
This, if anything, weakens the argument. The converter uses heat to produce energy. In the absence of heat, the convert is useless. (E) is out
(C) is the only one left. (C) is correct.
