If an engineer is designing a building in an area that has an occasional
supersonic flight pass over it, the engineer should:

a. design the building with extra stores of oxygen for the workers in
case of emergencies caused by sonic booms.
b. build the structure using materials that are heat resistant because
of the sonic booms.

c. design extra reinforcements in the building's windows so that they
can withstand the vibrations from sonic booms.

d. design the building with solar panels that can provide energy in
case of electrical outages due to sonic booms.
