The two main factors determining the climate of a region are its latitude and altitude. The three cities of Jubilee, Joy and Jest are all on the same latitude and are spread over only 100 miles on this line. However, the difference in temperature throughout most of the year between Jubilee and Jest on one side and Joy on the other is more than 30 degrees Fahrenheit.
Which of the following, if true, would most contribute to an explanation of the facts above?
(A) It is much harder to get to Joy by car than it is to get to Jubilee and Jest.
(B) While the city of Joy is quite a tourist attraction, only 0.5% of the revenue made in the cities of Jubilee and Jest comes from the tourism industry.
(C) During most of the year short clothes are worn in the city of Joy, while in Jubilee and in Jest warmer clothes are usually needed.
(D) While the city of Joy is situated high in the mountains, Jubilee and Jest are located not more than 200 feet above sea level.
(E) Whereas Joy is populated mostly by affluent people, Jubilee and Jest are home to many people of lower socio-economic status.
