Answer:
B
Explanation:
B is a better supported argument because it offers a reason behind the action that it wants to be taken. Argument B suggests that the city build new entrance and exit ramps, but it states that this needs to be done so that neighborhood blocks are not destroyed.
Argument A, on the other hand, specifies where it would like the ramps to be built, but it says nothing to support the argument by given the reasoning or purpose behind it.
