Electrical Engineers have developed an energy-efficient type of light bulbs that can replace the traditional incandescent bulb. The new bulb, known as the electronic lamp, operates by using a a high-frequency radio signal rather than d filament featured in incandescent bulbs. Although the electronic lamp currently costs 20 times as much as its tradional counterpart, its use will prove more cost effective in the long run. While a 100-watt incandescent bulb lasts 6 months if burned for 4 hours daily, a 25-watt electronic lamp used for the same amount of time each day lasts up to 14 years.
Argument above assumes that
A) the typical household use of light bulb is approx 4 hours a day
B) aside from its greater efficiency, the electronics lamp resembles the incandescent light bulb in most aspects
C) the type of light cast by the electronic lamp is different from that cast by an incandescent bulb.
D) the price of electronics lamps will decrease as they are produced in increasingly greater quantities.
E) a 100-watt incandescent light bulb does not provide significantly more light than a 25-watt electronic lamp.
