LR strengthen question
why does B strengthen? is this one of those anticipates a challenge answers or something? I went through the answers 3 times and could not pick one that strengthened and went with B as a best guess but still scratching my head.
PT 23, S3, #10: Strengthen
Core: If people walk whenever they can, then pollution will be significantly reduced
p1: If walk and not drive ---> less pollution
So just looking at it, I see a few things wrong, first off, the argument holds all things constant, and basically says, this thing contributes to pollution, so if we take that away, then there will be much less pollution. But what if, somehow, by not driving (walking everywhere) pollution does not decrease? Also it assumes that people do not already walk whenever they can. (I don't have the answers in front of me, but I'm positive that E addresses that in #9)
Moving to the answers:
A: Eliminate, this weakens hard
B: Hmm, this is relevant to my initial analysis of the argument, keep it.... Boom, this strengthen.
C: Weakens, only slightly though, due to the phrase it is possible, eliminate
D: Doesn't impact the core, eliminate
E: Weakens, slightly, due to the phrase it is possible, eliminate
Alright, so more on B. As you can tell I liked it initially, saved it, eliminated the rest, reviewed it and confirmed my suspicion that it strengthens. It strengthens because it addressed the underlying assumption that all other forms of pollution stay the same. If people walk and not drive, then congestion will decrease, and the amount of nonmoving vehicles will decrease. Think about waking up hungover, emailing your boss that you'll be be in at 9:30 from your phone, drinking your vitamin water, buying a shitty breakfast burrito, then heading to work at 9:15 AM, you might not make it. Traffic sucks at 9:00/9:15 AM, bumper to bumper all the way (congestion). But if all those people in front of you walked to work instead of driving, there would be less non-moving vehicles, leading to less congestion, leading to less pollution. B hits the gap on its head.
