However, the corresponding figure for the cars that the National Motor Company had manufactured in the 1960s was only five percent. Which one of the following, if true, most helps to explain the discrepancy? (A) Government motor vehicle regulations generally require all cars, whether old or new, to be inspected for emission levels prior to registration. (B) Owners of new cars tend to drive their cars more carefully than do owners of old cars. (C) The older a car is, the more likely it is to be discarded for scrap rather than repaired when major engine work is needed to keep the car in operation. (D) The cars that the National Motor Company built in the 1970s incorporated simplified engine designs that made the engines less complicated than those of earlier models. (E) Many of the repairs that were performed on the cars that the National Motor Company built in the 1960s could have been avoided if periodic routine maintenance had been performed. oa is c. why is D the correct answer here? Can you help with a detailed explanation pls ### GMAT/MBA Expert GMAT Instructor Joined 04 Oct 2017 Posted: 551 messages Followed by: 11 members Upvotes: 180 No need for a complicated explanation here. You ask why the answer is D, but it's not -- it's C. A higher percentage of the older cars were discarded, and that's why a smaller percent were repaired. Make sense? If not, let me know. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee. Our average student improves 98 points.
