参考答案

正确答案：C
解析：推断题。由第三段“，．．consolidation．．．means that most shippers are served by only one rail company．．．Shippers who feel that they are being overcharged have the right to appeal to the federal government．．．but the process is expensive，time consuming．．．”可见合并将会导致绝大部分shippers由一家rail company垄断(但不是所有的)，挨宰的人有权申诉但这一过程会耗费大量时间和金钱，所以他们一般不会诉诸法律，因此正确答案为C项。
