Since pollution-causing human activities can cause an increase in average global temperatures, the mild winters in the area could be a result of the high concentration of vehicle exhaust emitted in the region. however, some scientists argue that the mild winters are a result of the increased rate of conversion of commercial areas to industrial areas. which of the following, if true, strengthens the scientists' argument?
a) although commercial property areas tend to emit significantly less pollution than industrial areas, they still emit more than the vehicles in the area on a given day. b) most of the people who work in commercial areas drive to work each day. c) new strict laws in the area require buildings in the industrial areas to reduce their emissions by 60% in the next 5 years. d) vehicle exhaust is comprised largely of carbon monoxide, the same pollutant emitted by the industrial areas. e) in response to consumer demand, exhaust levels per vehicle have steadily decreased in recent years.

The correct answer is letter "C": New strict laws in the area require buildings in the industrial areas to reduce their emissions by 60% in the next 5 years.

Explanation:

According to the point of view of the author, the mild winters are caused due to high concentration of vehicle exhaust emitted in the region. However, from the research of the scientists, the mild winters are caused because of the increase in the rate of the commercial areas being changed into industrial areas. The idea that reinforces the scientists' point of view must blame the industrial workforce for the mild winters in the region. Out of the 5 options we have, letter "C" matches with the scientists position because if the new laws are already forcing industrial areas to reduce their emissions, it is because it has been proved that industrial areas are the main cause of the pollution in that region, not the concentration of vehicle exhaust as the author states.

explanation:

first, the romans stayed isolated because they had to defend their own territories from neighboring cities that were harassing them, like the etruscans. second, once the romans managed to defeat their neighbors, and started to expand their territory, they started to build roads and bridges. finally, now that the romans have covered their territory with roads functioning as highways, they could mobilize their legions faster to assemble larger military units in a specific place.
