Strengthening Argument About LED Bulbs

Very Hard Critical Reasoning Strengthening Arguments

In a recent statement, a leading environmental scientist claimed that replacing traditional incandescent light bulbs with LED bulbs will significantly reduce energy consumption in homes.

To support her statement, she pointed to a study which found that households using LED bulbs consumed 75% less energy for lighting. However, critics argue that the study did not account for the longer lifespan of incandescent bulbs, which might lead to a different overall expense for homeowners.

To strengthen the scientist’s argument, which of the following statements, if true, would provide the most support?

LED bulbs have a lifespan that is 25 times longer than that of incandescent bulbs.

Many households are unaware of how much energy they can save by switching to LED bulbs.

The costs of producing LED bulbs have decreased significantly in recent years.

The study compared homes with only LED bulbs to homes with mixed usage of LED and incandescent bulbs.
