B.
LEDs generally consume low amounts of power to produce light.
C.
Researchers have found that LEDs can have a negative effect on our health.
D.
Many traditional forms of lighting contain materials that can be dangerous.

Answer 1

The statement indicating that LEDs can negatively affect our health weakens the argument for their superiority over traditional lighting. It presents a potential health concern, contrasting with other statements about energy efficiency and environmental impact.

Step-by-step explanation:

The statement in the passage that weakens the argument that LEDs are better than traditional lighting systems is: 'Researchers have found that LEDs can have a negative effect on our health.' This statement goes against the benefits by highlighting a potential drawback of LED lights that concerns health, whereas the other statements highlight the improved energy efficiency and the presence of dangerous materials in traditional lighting.

When considering the replacement of traditional bulbs with LEDs, it is important to weigh all factors, including health implications, lifespan, environmental impact, and the initial investment cost of the lighting technology.
