My reasoning: "Our state has spent more money per mile on road improvements than any other state"
Option D states that no. of miles of road depends on the area and population of the state. It is not mentioned that other states are of equal area. So if this state has a greater area and population (supposedly) than amount spent on roads improvement will automatically becomes higher than other states and therefore attack this premise.
PERFECT. We have discovered something that you have to get better at.
To get these questions right you have to notice KEY DETAILS.
You missed THE key detail in the statement that you quoted above, the detail that makes option D irrelevant.
Now, you need to find that detail.
