Scientist: There is a finite amount of helium, which is a key component of MRI magnets, in the world. Because the supply is not renewable, it is frivolous to waste this precious resource on such products as party balloons. Instead, we should use other gases, such as hydrogen, to fill balloons, and the price of helium should be raised significantly to make it prohibitive for such trivial purposes.

Which of the following, if true, provides the strongest support for the suggestion that the price of helium should be raised?

【选项】The cost of the helium used for medical purposes is already significantly higher than helium sold on the open market.
