Question Stats:

Implementing extensive wireless networks in cities would be a practical way to meet the needs of city households, schools, and businesses. Rural communities have found that wireless networks are both more reliable and cheaper than land-based networks.

Which of the following would most likely be cited by a supporter of the argument?

(A) Urban areas do not pose additional problems for the effective operation of wireless networks.
(B) Wireless networks work far better where population density is low.
(C) Iceland, a very rural country, successfully uses wireless networks.
(D) The expense of wireless transmission in areas with large buildings is much higher than in areas without such buildings.
(E) Poor neighborhoods have less access to internet services than do educators or businesses.

This is a question in which we have to reinforce our argument for some reason.

Implementing extensive wireless networks in cities would be a practical way to meet the needs of city households, schools, and businesses. Rural communities have found that wireless networks are both more reliable and cheaper than land-based networks.


D is tempting but we do not know anything about a skyscraper or other buildings and the relative expenses. Moreover, we do not know if in rural areas we do not have buildings AT ALL.

Ask for further assistance if you do need.
