Article: Located in Chicago's Lake View neighborhood, Wrigley Field sits on an irregular block bounded by Clark and Addison Streets and Waveland and Sheffield Avenues. The area surrounding the ballpark is typically referred to as Wrigleyville. There is a dense collection of sports bars and restaurants in the area, most with baseball inspired themes, including Sluggers, Murphy's Bleachers and The Cubby Bear. Many of the apartment buildings surrounding Wrigley Field on Waveland and Sheffield Avenues have built bleachers on their rooftops for fans to view games and other sell space for advertisement. One building on Sheffield Avenue has a sign atop its roof which says "Eamus Catuli!" which is Latin for "Let's Go Cubs!" and another chronicles the time since the last Division title, pennant, and World Series championship. The 02 denotes two years since the 2008 NL Central title, 65 years since the 1945 pennant and 102 years since the 1908 World Series championship. On game days, many residents rent out their yards and driveways to people looking for parking spots. The uniqueness of the neighborhood itself has ingrained itself into the culture of the Chicago Cubs as well as the Wrigleyville neighborhood, and has led to being used for concerts and other sporting events, such as the 2010 NHL Winter Classic between the Chicago Blackhawks and Detroit Red Wings, as well as a 2010 NCAA men's football game between the Northwestern Wildcats and Illinois Fighting Illini.

Question: What is the area surrounding the ballpark typically referred to?
Ans: Wrigleyville

Here is a question about this article: Disadvantages of electric traction include high capital costs that may be uneconomic on lightly trafficked routes; a relative lack of flexibility since electric trains need electrified tracks or onboard supercapacitors and charging infrastructure at stations; and a vulnerability to power interruptions. Different regions may use different supply voltages and frequencies, complicating through service. The limited clearances available under catenaries may preclude efficient double-stack container service. The lethal voltages on contact wires and third rails are a safety hazard to track workers, passengers and trespassers. Overhead wires are safer than third rails, but they are often considered unsightly.
What is the answer to this question: What issue can complicate electric railway service?
****
So... different supply voltages and frequencies,

For those that remained under the Ottoman Empire's millet system, religion was the defining characteristic of national groups (milletler), so the exonym "Greeks" (Rumlar from the name Rhomaioi) was applied by the Ottomans to all members of the Orthodox Church, regardless of their language or ethnic origin. The Greek speakers were the only ethnic group to actually call themselves Romioi, (as opposed to being so named by others) and, at least those educated, considered their ethnicity (genos) to be Hellenic. There were, however, many Greeks who escaped the second-class status of Christians inherent in the Ottoman millet system, according to which Muslims were explicitly awarded senior status and preferential treatment. These Greeks either emigrated, particularly to their fellow Greek Orthodox protector, the Russian Empire, or simply converted to Islam, often only very superficially and whilst remaining crypto-Christian. The most notable examples of large-scale conversion to Turkish Islam among those today defined as Greek Muslims - excluding those who had to convert as a matter of course on being recruited through the devshirme - were to be found in Crete (Cretan Turks), Greek Macedonia (for example among the Vallahades of western Macedonia), and among Pontic Greeks in the Pontic Alps and Armenian Highlands. Several Ottoman sultans and princes were also of part Greek origin, with mothers who were either Greek concubines or princesses from Byzantine noble families, one famous example being sultan Selim the Grim, whose mother Gulbahar Hatun was a Pontic Greek.
What did it mean to be classified as a Greek by the millet command ?
****
The answer: was applied by the Ottomans to all members of the Orthodox Church, regardless of their language or ethnic origin.

Problem: Please answer a question about the following article about Dwight D. Eisenhower:
The development of the appreciation medals was initiated by the White House and executed by the Bureau of the Mint through the U.S. Mint in Philadelphia. The medals were struck from September 1958 through October 1960. A total of twenty designs are cataloged with a total mintage of 9,858. Each of the designs incorporates the text "with appreciation" or "with personal and official gratitude" accompanied with Eisenhower's initials "D.D.E." or facsimile signature. The design also incorporates location, date, and/or significant event. Prior to the end of his second term as President, 1,451 medals were turned-in to the Bureau of the Mint and destroyed. The Eisenhower appreciation medals are part of the Presidential Medal of Appreciation Award Medal Series.
During what period were the appreciation medals minted?
A: September 1958 through October 1960

France: The torch relay leg in Paris, held on April 7, began on the first level of the Eiffel Tower and finished at the Stade Charlety. The relay was initially supposed to cover 28 km, but it was shortened at the demand of Chinese officials following widespread protests by pro-Tibet and human rights activists, who repeatedly attempted to disrupt, hinder or halt the procession. A scheduled ceremony at the town hall was cancelled at the request of the Chinese authorities, and, also at the request of Chinese authorities, the torch finished the relay by bus instead of being carried by athletes. Paris City officials had announced plans to greet the Olympic flame with peaceful protest when the torch was to reach the French capital. The city government attached a banner reading "Paris defends human rights throughout the world" to the City Hall, in an attempt to promote values "of all humanity and of human rights." Members from Reporters Without Borders turned out in large numbers to protest. An estimated 3,000 French police protected the Olympic torch relay as it departed from the Eiffel Tower and criss-crossed Paris amid threat of protests. Widespread pro-Tibet protests, including an attempt by more than one demonstrator to extinguish the flame with water or fire extinguishers, prompted relay authorities to put out the flame five times (according to the police authorities in Paris) and load the torch onto a bus, at the demand of Chinese officials. This was later denied by the Chinese Ministry of Foreign Affairs, despite video footage broadcast by French television network France 2 which showed Chinese flame attendants extinguishing the torch. Backup flames are with the relay at all times to relight the torch. French judoka and torchbearer David Douillet expressed his annoyance at the Chinese flame attendants who extinguished the torch which he was about to hand over to Teddy Riner: "I understand they're afraid of everything, but this is just annoying. They extinguished the flame despite the fact that there was no risk, and they could see it and they knew it. I don't know why they did it."

What city in France did the torch relay start at?
Answer: Paris

The first law of thermodynamics asserts that energy (but not necessarily thermodynamic free energy) is always conserved and that heat flow is a form of energy transfer. For homogeneous systems, with a well-defined temperature and pressure, a commonly used corollary of the first law is that, for a system subject only to pressure forces and heat transfer (e.g., a cylinder-full of gas) without chemical changes, the differential change in the internal energy of the system (with a gain in energy signified by a positive quantity) is given as
What asserts that energy is always conserved and that heat flow is a form of energy transfer.
