A
New technologies that promise to extend life and decrease pain involve innovations that require extensive scientific research. Ttherefore, investment in such technologies is very risky, because innovations requiring extensive scientific research also require large amounts of capital but are unlikely to provide any financial return. Nonetheless, some people are willing to invest in these new technologies. Which one of the following, if true, most helps to explain why some people are willing to invest in new technologies that promise to extend life and decrease pain?
A: When investments in new technologies that promise to extend life and decrease pain do provide financial return, they generally return many times the original investment, which is much more than the return on safer investments.
B: A large variety of new technologies that promise to extend life and decrease pain have been developed in the last decade.
C: The scientific research necessary to develop new technologies that promise to extend life and decrease pain sometimes leads to no greater understanding of the natural world.
D: The development of certain new technologies other than those that promise to extend life and decrease pain is also very risky, because these technologies require large amounts of capital but are unlikely to provide any financial return.
