Rate the following argument fragment on its writing, argument, and language skills:
Evidence: For example, in source 1, by Elisabeth Rosenthal, it states that " And that, experts say, is a huge impediment to current efforts to drastically reduce greenhouse gas emissions from tailpipes....passenger cars are responsible for 12 percent of greenhouse gas emissions in Europe...and up to 50 percent in some car-intensive areas in the United States".  50 percent is a large number to be taken up by cars alone, if we can reduce car reduction, we can reduce greenhouse gasses.  Another example of why car reduction is an advantage is because of the pollution and smog areas.  You can clearly see this being stated in source 2, by Robert Duffer, "[The smog] rivaled Bejing, China, which is known as one of the most polluted cities in the world."  If Bejing, were to do what Paris did, they too could reduce smog and pollution by car reduction.  Also, in Bogota, Columbia, they have no car days, to limit the amount of smog.  However, limiting car usage to better the environment is not the only reason of why it is an advantage.
