Helium, a non renewable by-product of natural gas, is vital to the development of superconductor and other technology that are now emerging and will be important in the future. yet helium is being wasted when natural gas is extracted because of a lack of storage space for the helium. because helium is being wasted us industry will not have enough of the commodity when it needs it in the future.
which of the following, if true, would cast the most doubt on the accuracy of the prediction above?
a) in the us, the market price of the natural gas is rising sharply, while the market price of the helium remains unchanged.
b) the us government now maintains strategic stockpiles of helium so that some helium will be conserved for military uses.
c) recently discovered uses for helium can be expected to raise helium's price to the point where it will soon be economical to build excess storage capacity for helium in the us.
d) the number of newly discovered large natural gas deposits in the us has been declining each year for the past 5 years.
e) recently discovered superconductor that work at temperatures well above absolute zero have not been developed to the point where they are fully practical.
