When we refer to the assumptions as "incompatible" here, we mean that they are conflicting.
In specific, the two assumptions the author makes that conflict with each other are as follows: (1) proportional to current consumption rates, the author concludes that "a tax of fifty cents per gallon would therefore raise fifty billion dollars per year" (2) the author also says the tax would cause a "resulting drop in the demand for gasoline"
These two assumptions cannot both be true. If the first assumption is true and the tax raises an amount that is proportional to current consumption rates, then there would be no drop in demand like the second assumption says. If the second assumption is true and there is a drop in the demand for gasoline as a result of the tax, then the amount that the tax will raise would be lower than the estimates made in the first assumption based off consumption rates at the current level of demand.
Does that make sense? Please let us know if you have any other questions and best of luck with your studies!

Hello! I understand the question after you've explained it, but I have a general question, and I need to know what the difference between methods in reasoning and errors in reasoning. I put in my notes that method is the strategy and error is the flaw. I was reluctant I think to read carefully for this specific questions, but do you have a tip to differentiate the two question types? Thank you!

Hi,
Method of reasoning asks us to understand how the author supports their conclusion. All we need to do for them is understand how the argument is structured. For error in reasoning, we need to understand why the argument is flawed, to attack the argument.
