The price of titanium dioxide, a key ingredient in house paint, is increasing due to limited supplies because many mining companies that once produced titanium ore have shifted production to other ores. Without titanium dioxide, paint colors are less bright and more coats of paint must be applied to compensate. Companies that produce paint have concluded that they will soon need to increase the prices on the paint they produce. Which of the following would, if true, most strongly support the companies` conclusion?
【选项】Manufacturers of paint typically contract with chemical makers to lock in the price for at least a year's supply of titanium dioxide at a time.
