参考答案

正确答案：A
解析：推断题型见第二段第三句：Many a cowboy out on the lonely plains has been buried with a clean bandanna spread over his face to keep the dirt，or the coarse blanket on which the dirt was poured，from touching him. (许多牛仔一个个地出没在人迹罕至的草原上，人们在他们死后掩埋他们时会用一块干净的印花大手帕盖在他们的脸上以隔开泥土；或者用粗糙的毯子盖住他们的尸体以隔开掩埋他们的泥土)；由此可推断出用印花大手帕盖住死去的牛仔是为了keep the dirt from touching him... 以示对死者的尊敬；因此答案应为A。
