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
The question explains about a new technology- Palm Vein Technology, which can be used in tablets and laptops. But, the implementation of the technology requires the use of biometric sensors. The need for the technology is to do away with the problem of remembering multiple passwords.
We need to find the apt sentence which can fill the blanks.
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___________________________.
The blank should contain something about biometric sensors and the implementation cost or methods should be supportive or feasible to the success of the technology.
(A) the new technology is bound to be extremely popular with computer users.
Popular doesn’t connote the technology is feasible to implement. Hence, irrelevant.
(B) the biometric sensors do not cost a lot of money and are available in plentiful supply.
Option B - Which speaks about the supply of biometric sensors, doesn’t necessarily mean that the know how to incorporate the technology into the useable devices exist. Hence, it’s wrong.
(C) most people have forgotten one or more of their passwords at some point in their lives.
This is what is given in the question stem. Hence, irrelevant.
(D) there is almost always a market for innovations such as these.
Option D is wrong, because - the market is always available for new technologies like palm vein. But, the implementation is altogether a different ball game.
(E) the biometric sensors can be easily and cost effectively built into computers. This option is clearly correct. Because, the biometric sensor can be easily installed, which is one of the factor. And, the biometric sensor is extremely cost effective, which means the installation of these sensors is feasible.
Option E.
