GWD-29-Q1

More than fifty years after the Second World War, a number of African American soldiers were awarded ― some of them posthumously ― with the Congressional Medal of Honor, which was the nation’s highest military award, and which was long overdue in recognition of their outstanding bravery.  D/E

2. GWD-27-Q2:

Electronic computer chips made of tiny silicon wafers now regularly contain millions of electronic switches.  Unfortunately, electronic switches that are this small cannot withstand intense radiation.  Micro-Mechanics plans to produce a chip that, because it uses only microscopic mechanical switches, will be invulnerable to radiation damage.  The switches will, however, be slower than electronic switches and the 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:  B/E

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

2. 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.

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

4. 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.

5. Manufacturers are able to protect electronic computer chips against exposure to intense radiation, where this protection is necessary.

7. GWD27-Q7:Providing initial evidence that airport are a larger source of pollution than they were once believed to be, environmentalists in Chicago report that the total amount of pollutant emitted annually by vehicles at O’Hare International Airport is twice as much as that which is being emitted annually by all motor vehicles in the Chicago metropolitan area.
