Over the last few years, several car designers have won acclaim as art

Read this- "car designers must practice their craft with a focus on the practical utility of their designs" as "car designers are required to practice their craft with a focus on the practical utility of their designs"

Premise: car designers should focus on practical utility therefore they are not artist
Missing info: any design made for/on practical utility can not be considered as art form



a) Sometimes cars are designed just for exhibition and not for transportation.- Easy out no. 1, way out of focus, exhibition is not a part of the discussion

b) Some car designers are much more concerned about the practical use of their cars than other designers. - Runner up option, even if some car designers bother about the utility it does not say anything about the relation "car designers are not artists"

c) Car designers should pay more attention to the practical utility of their designs than they currently do. - Easy out no. 2, we are not at all bothered about the extent of focus of designers on the practical utility of their designs, it says nothing about the relation "car designers are not artists"

d) An object cannot be considered a work of art if its designer focuses on its practical utility. - Bingo!, this is what we were looking for. It tells the relation"car designers are not artists" straight and clearly

e) Artists don't care about how much money they earn through their work. - Easy out no. 3, way out of focus, just slash it
