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: Paper is often characterized by weight. In the United States, the weight assigned to a paper is the weight of a ream, 500 sheets, of varying "basic sizes", before the paper is cut into the size it is sold to end customers. For example, a ream of 20 lb, 8.5 in × 11 in (216 mm × 279 mm) paper weighs 5 pounds, because it has been cut from a larger sheet into four pieces. In the United States, printing paper is generally 20 lb, 24 lb, or 32 lb at most. Cover stock is generally 68 lb, and 110 lb or more is considered card stock.

A: What characteristic is paper usually classified by?

Q: The German Empire had primarily economic interests in Micronesia. The Japanese interests were in land. Despite the Marshalls' small area and few resources, the absorption of the territory by Japan would to some extent alleviate Japan's problem of an increasing population with a diminishing amount of available land to house it. During its years of colonial rule, Japan moved more than 1,000 Japanese to the Marshall Islands although they never outnumbered the indigenous peoples as they did in the Mariana Islands and Palau.

A:
About how many Japanese emigrated to the Marshalls when it was a Japanese colony?
