Suggestion:
1. To resolve problem of gridlocked vehicle traffic in major metropolitan areas = provide rickshaw or bike-cart service for trips of 5 to 25 city blocks.
Outcome if suggestion is implemented:
1. Implementing this remedy would be far cheaper than building overpasses to circumvent problem areas
2. This solution would also reduce the number of taxis clogging the roads.
We need to strengthen the argument by an evidence.
(A) An effective rickshaw system would require major repair of potholes.
--> This actually weakens the argument by indicating additional costs required for repair which will make the solution costlier.(B) Half of all car trips in the country’s most congested city cover distances of nine city blocks.
--> This strengthens the argument. At least 50% of car trips will be replaced by the rickshaw or bike-cart service.(C) The majority of rural travelers taking car trips in rural areas are traveling distances of over 25 city blocks.
--> Irrelevant. Argument is focused only on metropolitan areas.(D) Many new buses are being imported in areas presently served by existing rickshaw services.
--> Irrelevant. Existing rickshaw services are out of scope.(E) A large percentage of people driving in cities are tourists who are arriving from long-distance trips or are departing the city on long-distance trips.
--> Irrelevant. The suggestion is for travelling between 5 to 25 blocks. The tourists would still travel this distance in cars and increase the gridlock vehicle traffic.
