To improve its chance of winning the Monaco Grand Prix, Porsche needs to improve the acceleration on its cars. It can achieve the same by installing higher quality turbo chargers on its engines, thereby boosting their power output or by reducing weight of the car by rebuilding the chassis using carbon fiber instead of aluminum. Since reducing weight is estimated to improve the acceleration more than boosting engine power would, Porsche would be doing the most it can to improve acceleration if it decided to rebuild the chassis.
What is the assumption that the author makes while drawing his conclusion?
-
AMercedes, winner of last year's Monaco Grand Prix, has not reported opting for improved Turbo chargers this year over reduing weight.
分析该选项
-
BInstalling Turbo chargers and reducing weight will add negligibile incremental acceleration over any of individual enhancements.
分析该选项
-
CThe cost of adding incremental Carbon Fiber to the car will not cost Porsche so much that it is unable to participate in a few car races.
分析该选项
-
DNone of the teams are considering reduing the weight and boosting engine power output at the same time.
分析该选项
-
EUpgrading the gear transmission system will not increase the chancec of winning by enough.
