chip will contain only 12,000 switches.

For there to be a market for Micro-Mechanics' chip as a result of the apparent
advantage described above, each of the following would have to be true EXCEPT:

A. There will be applications in which the speed attainable by an electronic
switch is not essential.

B. Switches used on electronic chips that contain only 12,000 switches are more
vulnerable to radiation damage than the switches on Micro-Mechanics' chip
will be.

C. There will be applications for computer chips in environments where the chips
may have to survive intense radiation.

D. Some devices in which computer chips will be used will have other
components that will be able to function during or after exposure to radiation
.
E. Manufacturers are able to protect electronic computer chips against exposure
to intense radiation, where this protection is necessary.

Wat happened to u?? Take one more chance!!

The stimulus talks of two chips:
Chip 1:
"contain millions of electronic switches"
"cannot withstand intense radiation"
Chip 2:
MicroMechanics chip
uses only microscopic mechanical switches
"chip will contain only 12,000 switches"
"invulnerable to radiation damage"
"switches will, however, be slower than electronic switches"

Choice B states: Switches used on electronic chips that contain only 12,000 switches are more vulnerable to radiation damage than the switches on Micro-Mechanics' chip will be

It seems that a third chip, also with 12,000 switches, is being compared to the MicroMechanics chip.
Am I right?
For the MicroMechanics chip to have a market does it also have to perform better than this third chip or just being better that the fist chip (Chip 1 in stimulus) is sufficient?

TheGraduate wrote:Hi David,

Thanks a lot for your explanation. I got the point. However, I just want to confirm that choice B talks of a third chip (i.e. besides the two talked of in the stimulus).
