Hightower, a company occupying several office buildings, is considering installing energy-saving light bulbs in all of its buildings. This new light bulb emits as much light as the traditional light bulbs currently in use, and the required power is only traditional Half of the bulb. The life of this new bulb is also greatly extended, so by replacing the new bulb when the old bulb is broken, HighTower can greatly reduce its overall lighting costs. Which of the following, if true, best supports the above discussion? ['If this light bulb is widely adopted, it is very likely that the output of new light bulbs will increase greatly, making its price compared to those of traditional light bulbs.', 'Hightower recently signed a contract to occupy another small office building.', 'Hightower has launched a campaign to encourage its employees to turn off the lights every time they leave the room.', 'The company producing this new light bulb has patented the new technology used in the light bulb, so it has exclusive rights to produce the new light bulb.']
