The problem: Answer a question about this article:
Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).
How could an antenna be made to coordinate with the needed frequency?
****
The answer: built or ordered


Problem: Please answer a question about the following article about War on Terror:
In a major split in the ranks of Al Qaeda's organization, the Iraqi franchise, known as Al Qaeda in Iraq covertly invaded Syria and the Levant and began participating in the ongoing Syrian Civil War, gaining enough support and strength to re-invade Iraq's western provinces under the name of the Islamic State of Iraq and the Levant (ISIS/ISIL), taking over much of the country in a blitzkrieg-like action and combining the Iraq insurgency and Syrian Civil War into a single conflict. Due to their extreme brutality and a complete change in their overall ideology, Al Qaeda's core organization in Central Asia eventually denounced ISIS and directed their affiliates to cut off all ties with this organization. Many analysts[who?] believe that because of this schism, Al Qaeda and ISIL are now in a competition to retain the title of the world's most powerful terrorist organization.
What part of Iraq did ISIS invade?
A: western


Question: Read this and answer the question

While the republican government was amenable to war reparations or ceding colonial territories in Africa or in South East Asia to Prussia, Favre on behalf of the Government of National Defense, declared on 6 September that France would not "yield an inch of its territory nor a stone of its fortresses." The republic then renewed the declaration of war, called for recruits in all parts of the country and pledged to drive the German troops out of France by a guerre à outrance. Under these circumstances, the Germans had to continue the war, yet could not pin down any proper military opposition in their vicinity. As the bulk of the remaining French armies were digging-in near Paris, the German leaders decided to put pressure upon the enemy by attacking Paris. By September 15, German troops reached the outskirts of the fortified city. On September 19, the Germans surrounded it and erected a blockade, as already established at Metz.

What did this cause the Republic to renew?
Answer: declaration of war


Problem: Some street trams (streetcars) used conduit third-rail current collection. The third rail was below street level. The tram picked up the current through a plough (U.S. "plow") accessed through a narrow slot in the road. In the United States, much (though not all) of the former streetcar system in Washington, D.C. (discontinued in 1962) was operated in this manner to avoid the unsightly wires and poles associated with electric traction. The same was true with Manhattan's former streetcar system. The evidence of this mode of running can still be seen on the track down the slope on the northern access to the abandoned Kingsway Tramway Subway in central London, United Kingdom, where the slot between the running rails is clearly visible, and on P and Q Streets west of Wisconsin Avenue in the Georgetown neighborhood of Washington DC, where the abandoned tracks have not been paved over. The slot can easily be confused with the similar looking slot for cable trams/cars (in some cases, the conduit slot was originally a cable slot). The disadvantage of conduit collection included much higher initial installation costs, higher maintenance costs, and problems with leaves and snow getting in the slot. For this reason, in Washington, D.C. cars on some lines converted to overhead wire on leaving the city center, a worker in a "plough pit" disconnecting the plough while another raised the trolley pole (hitherto hooked down to the roof) to the overhead wire. In New York City for the same reasons of cost and operating efficiency outside of Manhattan overhead wire was used. A similar system of changeover from conduit to overhead wire was also used on the London tramways, notably on the southern side; a typical changeover point was at Norwood, where the conduit snaked sideways from between the running rails, to provide a park for detached shoes or ploughs.
What area in US discontinued using overhead wires for streetcars in 1962?
The answer is the following: Washington, D.C.


Napoleon instituted lasting reforms, including higher education, a tax code, road and sewer systems, and established the Banque de France, the first central bank in French history. He negotiated the Concordat of 1801 with the Catholic Church, which sought to reconcile the mostly Catholic population to his regime. It was presented alongside the Organic Articles, which regulated public worship in France. His dissolution of the Holy Roman Empire paved the way to German Unification later in the 19th century. The sale of the Louisiana Territory to the United States doubled the size of the country and was a major event in American history.
What was the name of the agreement that Napoleon arrived at with the Catholic Church?
the Concordat of 1801


Here is a question about this article: LeToya Luckett and Roberson became unhappy with Mathew's managing of the band and eventually were replaced by Farrah Franklin and Michelle Williams. Beyoncé experienced depression following the split with Luckett and Roberson after being publicly blamed by the media, critics, and blogs for its cause. Her long-standing boyfriend left her at this time. The depression was so severe it lasted for a couple of years, during which she occasionally kept herself in her bedroom for days and refused to eat anything. Beyoncé stated that she struggled to speak about her depression because Destiny's Child had just won their first Grammy Award and she feared no one would take her seriously. Beyoncé would later speak of her mother as the person who helped her fight it. Franklin was dismissed, leaving just Beyoncé, Rowland, and Williams.
What is the answer to this question: Who replaced Luckett and Roberson in Destiny's Child?
****
So...
Farrah Franklin and Michelle Williams.
