Problem: Party leaders of the United States House of Representatives:

A look at one minority leadership strategy—partisan opposition—may suggest why it might be employed in specific circumstances. The purposes of obstruction are several, such as frustrating the majority party's ability to govern or attracting press and media attention to the alleged ineffectiveness of the majority party. "We know how to delay," remarked Minority Leader Gephardt Dilatory motions to adjourn, appeals of the presiding officer's ruling, or numerous requests for roll call votes are standard time-consuming parliamentary tactics. By stalling action on the majority party's agenda, the minority leader may be able to launch a campaign against a "do-nothing Congress" and convince enough voters to put his party back in charge of the House. To be sure, the minority leader recognizes that "going negative" carries risks and may not be a winning strategy if his party fails to offer policy alternatives that appeal to broad segments of the general public.

Problem: Both low-cost and luxury housing were built by the government in the Brasília. The residential zones of the inner city are arranged into superquadras ("superblocks"): groups of apartment buildings along with a prescribed number and type of schools, retail stores, and open spaces. At the northern end of Lake Paranoá, separated from the inner city, is a peninsula with many fashionable homes, and a similar city exists on the southern lakeshore. Originally the city planners envisioned extensive public areas along the shores of the artificial lake, but during early development private clubs, hotels, and upscale residences and restaurants gained footholds around the water. Set well apart from the city are satellite cities, including Gama, Ceilândia, Taguatinga, Núcleo Bandeirante, Sobradinho, and Planaltina. These cities, with the exception of Gama and Sobradinho were not planned.
How are open spaces arranged in Brasilia?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The instruments used are a mixture of Anatolian and Central Asian instruments (the saz, the bağlama, the kemence), other Middle Eastern instruments (the ud, the tanbur, the kanun, the ney), and—later in the tradition—Western instruments (the violin and the piano). Because of a geographic and cultural divide between the capital and other areas, two broadly distinct styles of music arose in the Ottoman Empire: Ottoman classical music, and folk music. In the provinces, several different kinds of folk music were created. The most dominant regions with their distinguished musical styles are: Balkan-Thracian Türküs, North-Eastern (Laz) Türküs, Aegean Türküs, Central Anatolian Türküs, Eastern Anatolian Türküs, and Caucasian Türküs. Some of the distinctive styles were: Janissary Music, Roma music, Belly dance, Turkish folk music.
What are the three most used Anatolian and central asian instruments in Ottoman Classical music?
A: the saz, the bağlama, the kemence


Context and question: There is usually an indication for a specific identification of an infectious agent only when such identification can aid in the treatment or prevention of the disease, or to advance knowledge of the course of an illness prior to the development of effective therapeutic or preventative measures. For example, in the early 1980s, prior to the appearance of AZT for the treatment of AIDS, the course of the disease was closely followed by monitoring the composition of patient blood samples, even though the outcome would not offer the patient any further treatment options. In part, these studies on the appearance of HIV in specific communities permitted the advancement of hypotheses as to the route of transmission of the virus. By understanding how the disease was transmitted, resources could be targeted to the communities at greatest risk in campaigns aimed at reducing the number of new infections. The specific serological diagnostic identification, and later genotypic or molecular identification, of HIV also enabled the development of hypotheses as to the temporal and geographical origins of the virus, as well as a myriad of other hypothesis. The development of molecular diagnostic tools have enabled physicians and researchers to monitor the efficacy of treatment with anti-retroviral drugs. Molecular diagnostics are now commonly used to identify HIV in healthy people long before the onset of illness and have been used to demonstrate the existence of people who are genetically resistant to HIV infection. Thus, while there still is no cure for AIDS, there is great therapeutic and predictive benefit to identifying the virus and monitoring the virus levels within the blood of infected individuals, both for the patient and for the community at large.
What could be in danger by understanding how the disease was transmitted?

Question: Another deck structure that can be seen is a ski-jump ramp at the forward end of the flight deck. This was first developed to help launch STOVL aircraft take off at far higher weights than is possible with a vertical or rolling takeoff on flat decks. Originally developed by the Royal Navy, it since has been adopted by many navies for smaller carriers. A ski-jump ramp works by converting some of the forward rolling movement of the aircraft into vertical velocity and is sometimes combined with the aiming of jet thrust partly downwards. This allows heavily loaded and fueled aircraft a few more precious seconds to attain sufficient air velocity and lift to sustain normal flight. Without a ski-jump launching fully loaded and fueled aircraft such as the Harrier would not be possible on a smaller flat deck ship before either stalling out or crashing directly into the sea.
Is there an answer to this question: What does a ski-jump ramp convert in order to be a failure?

Answer: unanswerable


QUES: After Germany invaded the Soviet Union on 22 June 1941, the Wehrmacht crossed the Estonian southern border on 7 July. The Red Army retreated behind the Pärnu River – Emajõgi line on 12 July. At the end of July the Germans resumed their advance in Estonia working in tandem with the Estonian Forest Brothers. Both German troops and Estonian partisans took Narva on 17 August and the Estonian capital Tallinn on 28 August. After the Soviets were driven out from Estonia, German troops disarmed all the partisan groups.

When did the Red Army fall back to the Parnu River?
