Adam: Marking road edges with reflecting posts gives drivers a clear view of the edges, thereby enabling them to drive more safely. Ttherefore, marking road edges with reflecting posts will decrease the annual number of road accidents. Aiesha: You seem to forget that drivers exceed the speed limit more frequently and drive close to the road edge more frequently on roads that are marked with reflecting posts than on similar roads without posts, and those are driving behaviors that cause road accidents. Aiesha responds to Adam's argument by ["raising a consideration that challenges the argument's assumption that facilitating safe driving will result in safer driving", 'providing additional evidence to undermine the claim that safer driving does not necessarily reduce the number of road accidents', "questioning Adam's assertion that reflecting posts give drivers a clear view of road edges", 'presenting a possible alternative method for decreasing road accidents']
