An analyst argues that a rapid transition from conventional to electric cars would continue to put a strain on natural resources. This would best be explained by:
选项：
A.population growth. B.the Jevons paradox. C.the shift in materials used.解释：
C is correct because one of the aspects related to a further strain on natural resources and their depletion is the result of the shift in materials used in production. "Another aspect is the shift in the resources used. For example: Clean energy technologies generally require more minerals than fossil fuel-based counterparts. An electric car uses five times as much minerals as a conventional car (...)."
A is incorrect because population growth would not be the?most likely?reason behind a strain on natural resources related to rapid transition from conventional to electric cars. Population growth, in general, is listed among the biggest causes of increased pressure on natural resources: "The rising population will put increased strain on the world’s natural resources, most notably in terms of access to food." However, the main source of a strain related to rapid transition of the industry is stemming from the change in resources used and the fact that the new technology requires more of the minerals. "Clean energy technologies generally require more minerals than fossil fuel-based counterparts. An electric car uses five times as much minerals as a conventional car (...)."
B is incorrect because the Jevons paradox is observed when "(...) relative improvements in efficiency (using fewer resources per unit of production) may be offset by increased consumption of a given product." However, switching rapidly production line from conventional to electric cars means using more resources than for fuel-based vehicles (per car produced): "An electric car uses five times as much minerals as a conventional car (...)."
B为什么错了
