A、Letter from a Student
A、letter written by a student proposes that the running trails around campus be paved over with cement. His suggestion is based on the following considerations: First, the current trails are made of sand and always get muddy after it rains. The runners slip very easily on the sandy trails. However, a cement trail would be skid-proof and much safer. Second, cement trails look nicer, and would attract more runners.
Question: The man expresses his opinion towards the student letter. State his opinion and explain the reasons he gives for holding that opinion.
