Our marketing Class at university was discussing an elevator company that sold its products worldwide.
我們大學行銷課裡正在討論一家全球行銷的電梯公司。

The professor had listed on the blackboard some forces influencing the company's operations, including political climate, currency restrictions and import quotas.
教授將影響公司營運的一些力量列在黑板上，包括政治氣侯、貨幣限制與進口配額。

When he asked if anyone could name other forces that would have an impact on an international elevator company, a voice from the back called out, "Gravity."
當他詢問是否有人可以指出，其他可對國際電梯公司造成衝擊的力量。有個聲音從後面叫了出來：「重力」！
