Question 2 A manufacturing plant uses two tanks to store certain liquid chemicals that are required in a manufacturing process. Each tank has a sensor that detects when the chemical level drops to

of full. The sensors produce a HIGH level of 5 V when the tanks are more than onequarter full. When the volume of chemical in a tank drops to one-quarter full, or less the sensor puts out a LOW level of 0 V . It is required that a single green light-emitting diode (LED) on an indicator panel shows when both tanks are more than one-quarter full.
