Article: Incandescent bulbs are much less efficient than most other types of electric lighting; incandescent bulbs convert less than 5% of the energy they use into visible light, with standard light bulbs averaging about 2.2%. The remaining energy is converted into heat. The luminous efficacy of a typical incandescent bulb is 16 lumens per watt, compared with 60 lm/W for a compact fluorescent bulb or 150 lm/W for some white LED lamps. Some applications of the incandescent bulb deliberately use the heat generated by the filament. Such applications include incubators, brooding boxes for poultry, heat lights for reptile tanks, infrared heating for industrial heating and drying processes, lava lamps, and the Easy-Bake Oven toy. Incandescent bulbs typically have short lifetimes compared with other types of lighting; around 1,000 hours for home light bulbs versus typically 10,000 hours for compact fluorescents and 30,000 hours for lighting LEDs.

Question: Which is more efficient: compact fluorescent or LED lights?
Ans: LED

Here is a question about this article: During the Consulate, Napoleon faced several royalist and Jacobin assassination plots, including the Conspiration des poignards (Dagger plot) in October 1800 and the Plot of the Rue Saint-Nicaise (also known as the Infernal Machine) two months later. In January 1804, his police uncovered an assassination plot against him that involved Moreau and which was ostensibly sponsored by the Bourbon family, the former rulers of France. On the advice of Talleyrand, Napoleon ordered the kidnapping of the Duke of Enghien, violating the sovereignty of Baden. The Duke was quickly executed after a secret military trial, even though he had not been involved in the plot. Enghien's execution infuriated royal courts throughout Europe, become one of the contributing political factors for the outbreak of the Napoleonic Wars.
What is the answer to this question: The kidnapping of the Duke of Enghien violated the sovereignty of what locale?
****
So... Baden

The problem: Answer a question about this article:
For "closed systems" with no external source or sink of energy, the first law of thermodynamics states that a system's energy is constant unless energy is transferred in or out by mechanical work or heat, and that no energy is lost in transfer. This means that it is impossible to create or destroy energy. While heat can always be fully converted into work in a reversible isothermal expansion of an ideal gas, for cyclic processes of practical interest in heat engines the second law of thermodynamics states that the system doing work always loses some energy as waste heat. This creates a limit to the amount of heat energy that can do work in a cyclic process, a limit called the available energy. Mechanical and other forms of energy can be transformed in the other direction into thermal energy without such limitations. The total energy of a system can be calculated by adding up all forms of energy in the system.
How can the total energy of a system be calculated?
****
The answer: by adding up all forms of energy in the system

Problem: Please answer a question about the following article about Beyonce:
Beyonce participated in George Clooney and Wyclef Jean's Hope for Haiti Now: A Global Benefit for Earthquake Relief telethon and was named the official face of the limited edition CFDA "Fashion For Haiti" T-shirt, made by Theory which raised a total of $1 million. On March 5, 2010, Beyonce and her mother Tina opened the Beyonce Cosmetology Center at the Brooklyn Phoenix House, offering a seven-month cosmetology training course for men and women. In April 2011, Beyonce joined forces with US First Lady Michelle Obama and the National Association of Broadcasters Education Foundation, to help boost the latter's campaign against child obesity by reworking her single "Get Me Bodied". Following the death of Osama bin Laden, Beyonce released her cover of the Lee Greenwood song "God Bless the USA", as a charity single to help raise funds for the New York Police and Fire Widows' and Children's Benefit Fund.
Beyonce opened a cosmetology center in what location?
A: Brooklyn Phoenix House

According to a tradition first reported by Sulcard in about 1080, a church was founded at the site (then known as Thorn Ey (Thorn Island)) in the 7th century, at the time of Mellitus, a Bishop of London. Construction of the present church began in 1245, on the orders of King Henry III.

When was construction of the present church started?
Answer: 1245

Despite its domestic focus, the FBI also maintains a significant international footprint, operating 60 Legal Attache (LEGAT) offices and 15 sub-offices in U.S. embassies and consulates across the globe. These overseas offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA has a limited domestic function; these activities generally require coordination across government agencies.
What do oversea operations require?
coordination
