State researchers have found that since the oil price increases of the 1970s, there has been a decline in home energy consumption. They
concluded that almost all of the decline has been achieved through reduced standards of living and changes in the way people spend their time.
Each of the following, if true, would support the conclusion above EXCEPT:
(A) Sales of portable heaters rose as families
concentrated their winter activities in a limited number of rooms. - WRONG. Complies with standard of living.
(B)
During the winter months, more people frequented public places such as libraries and community centers and, on the average,
spent considerably longer periods in them than they had previously. - Complies with the way people spend their time.
(C)
More than 39 percent of households were able to
decrease energy costs substantially by having relatively inexpensive work done to
improve the efficiency of their existing heating systems. - CORRECT. This encapsulates everything what passage mentions, confusing things in a manner that it looks enticing to chose as right answer. But this confusion itself is a red flag as in how >39% is enough to lead to decrease in cost. It uses similar sounding words to trap test taker.
(D)
At least 59 percent of households maintained a lower indoor temperature than they had been accustomed to maintain on very cold days. - WRONG. Complies with standard of living.
(E) Members of
at least 60 percent of households showered for shorter periods of time than they had previously. - WRONG. Complies with standard of living.
If someone concentrates how home energy consumption declined then he/she may falter in identifying the right option. The second sentence is the conclusion wherein two parameters are set within which out of five four should comply.
Answer C.
