Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Q: LED lamps have been advocated as the newest and best environmental lighting method. According to the Energy Saving Trust, LED lamps use only 10% power compared to a standard incandescent bulb, where compact fluorescent lamps use 20% and energy saving halogen lamps 70%. The lifetime is also much longer — up to 50,000 hours. A downside is still the initial cost, which is higher than that of compact fluorescent lamps.

A: How much more power does a standard incandescent bulb use compared to LED?

Q: In Western societies, skirts, dresses and high-heeled shoes are usually seen as women's clothing, while neckties are usually seen as men's clothing. Trousers were once seen as exclusively male clothing, but are nowadays worn by both genders. Male clothes are often more practical (that is, they can function well under a wide variety of situations), but a wider range of clothing styles are available for females. Males are typically allowed to bare their chests in a greater variety of public places. It is generally acceptable for a woman to wear traditionally male clothing, while the converse is unusual.

A: What is an example of clothing that was once seen as exclusively for males?

Q: Endospores show no detectable metabolism and can survive extreme physical and chemical stresses, such as high levels of UV light, gamma radiation, detergents, disinfectants, heat, freezing, pressure, and desiccation. In this dormant state, these organisms may remain viable for millions of years, and endospores even allow bacteria to survive exposure to the vacuum and radiation in space. According to scientist Dr. Steinn Sigurdsson, "There are viable bacterial spores that have been found that are 40 million years old on Earth — and we know they're very hardened to radiation." Endospore-forming bacteria can also cause disease: for example, anthrax can be contracted by the inhalation of Bacillus anthracis endospores, and contamination of deep puncture wounds with Clostridium tetani endospores causes tetanus.

A:
Is there a metabolism in endospores?
