Problem: Freemasonry:

English Freemasonry spread to France in the 1720s, first as lodges of expatriates and exiled Jacobites, and then as distinctively French lodges which still follow the ritual of the Moderns. From France and England, Freemasonry spread to most of Continental Europe during the course of the 18th century. The Grande Loge de France formed under the Grand Mastership of the Duke of Clermont, who exercised only nominal authority. His successor, the Duke of Orleans, reconstituted the central body as the Grand Orient de France in 1773. Briefly eclipsed during the French Revolution, French Freemasonry continued to grow in the next century.

Who was the successor to the Duke of Clermont?
---
A: Duke of Orleans

Problem: Infrared:

Infrared radiation is used in industrial, scientific, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds; detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.

What technology allows infrared thermal imaging cameras to observe people or animals without being detected?

A: unanswerable

Problem: States of Germany:

The municipalities have two major policy responsibilities. First, they administer programs authorized by the federal or state government. Such programs typically relate to youth, schools, public health, and social assistance. Second, Article 28(2) of the Basic Law guarantees the municipalities "the right to regulate on their own responsibility all the affairs of the local community within the limits set by law." Under this broad statement of competence, local governments can justify a wide range of activities. For instance, many municipalities develop and expand the economic infrastructure of their communities through the development of industrial trading estates.

What guarantees state and federal governments their rights?
---
A: unanswerable

Problem: Light-emitting diode:

In the US, one kilowatt-hour (3.6 MJ) of electricity currently causes an average 1.34 pounds (610 g) of CO
2 emission. Assuming the average light bulb is on for 10 hours a day, a 40-watt bulb will cause 196 pounds (89 kg) of CO
2 emission per year. The 6-watt LED equivalent will only cause 30 pounds (14 kg) of CO
2 over the same time span. A building's carbon footprint from lighting can therefore be reduced by 85% by exchanging all incandescent bulbs for new LEDs if a building previously used only incandescent bulbs.

A 9-watt LED left on for 10 hours a day will emit how much CO 2?

A:
unanswerable
