PrepTest February 1997 - Section 1 - Question 14 - AC E #help
I am confused here as to why AC E does not work. Although I have my own reasons, I am just looking for some confirmation on my thinking here since there is no explanation posted for this question yet.
From my understanding of the passage, we see no difference in the number of collisions at place that used to require headlights only when visibility was poor which then switched to having headlights mandatory at all time.
E seems to resolve this paradox. If a place used to only require headlights be turned on in poor visibility, but visibility is also poor all of the time, then we would expect everyone's headlights to be on all of the time. Thus, implementing a new law that makes it mandatory for headlights to be on regardless of visibility would have no impact on this, resolving the paradox.
Is the reasoning for E being incorrect the use of the word "frequently" rather than "always"? Thus implying that there may still be SOME difference? I can definitely see that being the case.
As for AC C being correct, is this due to AC C establishing that the use of headlights has no causal effect on collisions, and instead is simply case of correlation between safe drivers and headlight usage? It would then logically follow that increasing the use of headlights would actually have no impact on collisions, since now we will just have the unsafe drivers also using headlights at all time.
