Which of the following most logically completes the argument below?
A new palm vein scanning technology is being developed by scientists that could be used with laptops or other tablet devices. This technology involves the use of a biometric sensor that can scan the unique pattern of veins in a person’s palm to verify their identity. This technology could do away with the problem of remembering multiple passwords to access different websites. However, the technology would require new biometric sensors to be built into computers but this should not be a hindrance in the success of the new technology, because___________________________.
(A) the new technology is bound to be extremely popular with computer users
(B) the biometric sensors do not cost a lot of money and are available in plentiful supply
(C) most people have forgotten one or more of their passwords at some point in their lives
(D) there is almost always a market for innovations such as these
(E) the biometric sensors can be easily and cost effectively built into computers
Official Explanation
Answer: E
Since the leading word is because, we need to strengthen the conclusion that the requirement of biometric sensors to be built into computers will not be a problem. E does this best and is the correct answer.
(A) The technology may be popular but if this technology is very expensive then most people may not be able to afford it.
(B) Even if the biometric sensors themselves are cheap, their installation in computers could be very expensive.
(C) Irrelevant fact.
(D) The market may not be there if these innovations become very costly.
(E) The correct answer.
