Great question!
To figure out which piece of information would support Passage B's position over Passage A's, we should first identify what each passage takes as its primary "position".
Passage A argues that a flat tax can be practically implemented, and it can be fair/progressive (or at least, as fair/progressive as a graduated tax is currently). Passage B, in contrast, raises the very fairness objection Passage A intends to quell - that a graduated tax is the more 'fair' option, since the survival dollars are fundamentally different from discretionary dollars.
So, what could support B over A here? Well, anything that showed the flat tax to be less fair/progressive than the current graduated tax would support A, and weaken B!
In (D), if middle-income taxpayers pay more under the flat tax, and Passage A told us that high-income taxpayers pay about the same amount, that means that the burden has shifted more heavily onto the middle-come taxpayers - and that's less progressive than the current situation with a graduated tax!
As you note, that this answer would support Author's B's position is far more directly shown at the very end of Passage B. Since we have a scenario that would show the flat tax to be less progressive than the graduated tax, the answer supports B *over* A.
Let's take a look at the incorrect answer choices, now that we have a strong sense of the positions of the two passages.
(A) - This issue would be relevant if the two authors fundamentally disagreed on whether the flat tax would bring in the same revenue - their disagreement is over HOW it will end up bringing in that revenue. Neither side argues that the flat tax wouldn't bring in revenue.
(B) - Author A mentions the complexity of the current tax code, and so probably believes that a flat tax would reduce complexity, so this would probably support Author A. Additionally, Author B never weighs in on whether the flat tax would be simpler.
(C) - Neither author mentions how taxpayers ultimately feel about the taxes, or whether they *believe* they are overtaxed - they only discuss where the money will actually flow from.
(E) - Neither author discusses whether or not legislators are in favor of a flat tax or not, so this wouldn't support either author over the other one.
Remember, if you have to support one passage's position, it's critical to take a moment and identify what the essential position of each passage is before you go trying to support it! Since Author A is trying to make a point about the potential for fairness in a flat tax, anything impacting that fairness argument is fair game, even though he did not specifically mention anything about middle-income taxpayers in particular.
Please let me know if this completely clears up your question!
