Food is in short supply all over the country.

食品在全国各地都供应不足。

Exploitable raw materials were in short supply.

可开采的原料供应短缺。

Water are still in short supply in many areas.

许多地区仍然供水不足。

So why, then, are women in short supply at the top of government and business in the United States?

那么，为什么女性在美国政府和企业的高层职位中供不应求呢？

If the product is in short supply relative to the demand, the price will be bid up and some consumers will be eliminated from the market.

如果产品供不应求，价格就会被哄抬，一些消费者就会被淘汰出市场。
