This is a q that tests general reasoning skills -- we're always going to want to find the best available answer in this situation by eliminating wrong ones --
(A) places too much emphasis on one aspect of New Urbanism. "Primary" is a big red flag.
(B) goes well beyond the scope of what is discussed.
(C) goes well beyond the scope of what is discussed.
(E) is tempting, because it seems to echo the last part of the passage, but it too is too strong -- are the authors really saying that personal values should NOT at all affect how neighborhoods are designed? That seems way too extreme, and indeed it is.
The movement feels negatively towards the overemphasis of some personal values, but they certainly don't advocate such extreme government control.
That leaves (D), the only reasonable answer --
(D) has two components --
1) the configuration of neighborhoods influences attitudes -- this is proved abundantly throughout the passage
2) configuration influenced by attitudes -- this is mentioned in the last paragraph --
therefore, we have pretty ample evidence that the New Urbanists would likely agree w/this assessment.
Hope that helps!
