问题如下：
The owner of a machine factory finds that his firm has a total cost larger than total revenue, and the total revenue is larger than total variable cost, the decision he will least likely make is:
选项：
A.stay in the market in the short term.
B.shut down the firm in the long term.
C.shut down the firm in the short and long term.
解释：
B is correct.
When TC>TR>TVC, the firm should continue to operate in the short run but shutdown in the long run. Since the firm will face a loss, but fixed cost can be compensated at a certain level.
考点：停止营业点
解析：当总的收益超过了可变成本，但是不足以覆盖总固定成本时，该厂商就应该在短期继续生产，因为继续生产就可以弥补一定的固定成本损失，但是在长期，该厂商应该退出生产。
答案应该是C，不应该在长期短期都退出。答案顺序变化了，但是答案结果没变。
