Wide dissemination of wireless networks in cities is a practical way

IMO: A. We are asked to pick a choice that a supporter of the conclusion will endorse. The passage concludes that deploying wireless networks is advantageous. So, a supporter of this conclusion will only talk about the advantages and not mention the disadvantages. Which of the choices support wireless networks? Choice A.

My answer is A.
The passage specifies wireless networks are useful in cities as well as rural communities.

• Urban areas do not pose additional problems for the effective operation of wireless networks.
>> Yes. This is how I see the passage.
• Wireless networks work far better where population density is low.
>> Not mentioned in passage.
• Iceland, a very rural country, successfully uses wireless networks.
>> Not related here.
• The expenses of wireless transmission in areas with large buildings is much higher.
>> Not mentioned about expense.
• Poor neighborhoods have less access to cable internet than do educators or businesses.
>> This sentence can not be inferred from passage given.

Argument is:
- wireless is good in rural areas.
- would therefore be good in urban areas

This argument is quite weak. The first reaction is "but what works in rural areas may not work in cities"! A nicely resolves this issue.

Argument is now:
- wireless is good in rural areas.
- no obstacles to transferring this to urban areas
- would therefore be good in urban areas

I have found this one very tricky. I didn't understand that this one was a strengthen question because I didn't find the conclusion. In stimulus like this one, how can you find the conclusion?

What's wrong with C? Doesn't it directly support the argument?

The conditions in Iceland may not be same as conditions in the villages where wireless networks are being considered. Therefore this reasoning in not a very strong supporter for the argument. Nonetheless option C does have a weak support for the argument, but the support provided by option A is stronger and hence better.

Negate both statement and see which one weakens the argument more. Negativng option A weakens the argument, almost to the point of breaking it down. Negating option C weakens as well, but generalising from one example is not a severe weakener (or a strengthener).

Dissemination :- the act of spreading something, especially information, widely; circulation.
The argument claims that wide dissemination of wireless access is now a practical way to meet urban needs, based on the evidence of its successful use in rural areas. The author then must assume that urban areas provide no additional problems for wireless use.
A supporter would cite something that bolsters the argument.

Conclusion - Wide dissemination of wireless networks in cities is a practical way to meet the needs of city households, schools and businesses
Premise - Rural communities have found that wireless networks are both more reliable and cheaper than land-based networks.

One can 'directionally' prephrase the answer, we have to prove that wireless dissemination in cities is a good idea and the evidence given to support it is that it works well in rural areas, if somehow we can link the rural wireless effectiveness to the urban setting we are good to go!

Moving to the answer choices.
A - Good! Makes the connection between rural and urban conditions. Mark as a contender
B - Oops! If wireless works better in low density areas (aka rural areas) it is a problem, because cities might not be low density areas. Hence reject.
C - Great that Iceland uses wireless and it is rural but it still misses the rural to urban connect. Hence reject.
D - Nah! If this is true wireless in cities not a good idea.
E - The argument is not about rich or poor neighborhoods, it is about wireless in cities. This choice is way off the mark.

Hence A.

Sorry, weirdly worded argument. When I saw this question, I spent a minute to link the 2 sentences and ultimately couldn't link first 2 sentences. Looking at the replies here, except for one by Anaira Mitch, no one links the answers correctly. It is bad qn.
