Tuberculosis is classified as one of the granulomatous inflammatory diseases. Macrophages, T lymphocytes, B lymphocytes, and fibroblasts aggregate to form granulomas, with lymphocytes surrounding the infected macrophages. When other macrophages attack the infected macrophage, they fuse together to form a giant multinucleated cell in the alveolar lumen. The granuloma may prevent dissemination of the mycobacteria and provide a local environment for interaction of cells of the immune system. However, more recent evidence suggests that the bacteria use the granulomas to avoid destruction by the host's immune system. Macrophages and dendritic cells in the granulomas are unable to present antigen to lymphocytes; thus the immune response is suppressed. Bacteria inside the granuloma can become dormant, resulting in latent infection. Another feature of the granulomas is the development of abnormal cell death (necrosis) in the center of tubercles. To the naked eye, this has the texture of soft, white cheese and is termed caseous necrosis.
What natural defensive response is hindered by cells in granulomas that can't send antigen to lymphocytes?
immune response


Input: Crimean War
In the west, the Russians were dissuaded from attacking Vidin by the presence of the Austrian forces, which had swelled to 280,000 men. On 28 May 1854 a protocol of the Vienna Conference was signed by Austria and Russia. One of the aims of the Russian advance had been to encourage the Orthodox Christian Serbs and Bulgarians living under Ottoman rule to rebel. However, when the Russian troops actually crossed the River Pruth into Moldavia, the Orthodox Christians still showed no interest in rising up against the Turks.:131, 137 Adding to the worries of Nicholas I was the concern that Austria would enter the war against the Russians and attack his armies on the western flank. Indeed, after attempting to mediate a peaceful settlement between Russia and Turkey, the Austrians entered the war on the side of Turkey with an attack against the Russians in the Principalities which threatened to cut off the Russian supply lines. Accordingly, the Russians were forced to raise the siege of Silistra on 23 June 1854, and begin abandoning the Principalities.:185 The lifting of the siege reduced the threat of a Russian advance into Bulgaria.

Who stopped the Russians from attacking Vidin?
Output: Austrian forces


Input: Article: Portuguese cuisine is diverse. The Portuguese consume a lot of dry cod (bacalhau in Portuguese), for which there are hundreds of recipes. There are more than enough bacalhau dishes for each day of the year. Two other popular fish recipes are grilled sardines and caldeirada, a potato-based stew that can be made from several types of fish. Typical Portuguese meat recipes, that may be made out of beef, pork, lamb, or chicken, include cozido à portuguesa, feijoada, frango de churrasco, leitão (roast suckling pig) and carne de porco à alentejana. A very popular northern dish is the arroz de sarrabulho (rice stewed in pigs blood) or the arroz de cabidela (rice and chickens meat stewed in chickens blood).

Now answer this question: Other than bacalhau, what are two other popular fish recipes in Portugal?

Output: grilled sardines and caldeirada


Article: The route carried the torch through six continents from March 2008 to May 2008 to August 2008. The planned route originally included a stop in Taipei between Ho Chi Minh City and Hong Kong, but there was disagreement in Beijing and Taipei over language used to describe whether it was an international or a domestic part of the route. While the Olympic committees of China and Chinese Taipei reached initial consensus on the approach, the government of the Republic of China in Taiwan intervened, stating that this placement could be interpreted as placing Taiwan on the same level as Hong Kong and Macau, an implication it objected to. The Beijing Organizing Committee attempted to continue negotiation, but further disputes arose over the flag or the anthem of the Republic of China along the 24 km torch route in Taiwan. By the midnight deadline for concluding the negotiation on September 21, 2007, Taiwan and China were unable to come to terms with the issue of the Torch Relay. In the end, both sides of the Taiwan Strait decided to eliminate the Taipei leg.

Question: How many kilometers was the torch supposed to go through Taiwan?
Ans: 24


Here is a question about this article: Rear Admiral Bradley A. Fiske was at the vanguard of new technology in naval guns and gunnery, thanks to his innovations in fire control 1890–1910. He immediately grasped the potential for air power, and called for the development of a torpedo plane. Fiske, as aide for operations in 1913–15 to Assistant Secretary Franklin D. Roosevelt, proposed a radical reorganization of the Navy to make it a war-fighting instrument. Fiske wanted to centralize authority in a chief of naval operations and an expert staff that would develop new strategies, oversee the construction of a larger fleet, coordinate war planning including force structure, mobilization plans, and industrial base, and ensure that the US Navy possessed the best possible war machines. Eventually, the Navy adopted his reforms and by 1915 started to reorganize for possible involvement in the World War then underway.
What is the answer to this question: What aircraft did Fiske call for the development of?
****
So... torpedo plane


Article: In most nations with constitutions modelled after the Soviet Union, the legislature was given the power of being the court of last resort. In the People's Republic of China, the final power to interpret the law is vested in the Standing Committee of the National People's Congress (NPCSC). This power includes the power to interpret the basic laws of Hong Kong and Macau, the constitutional documents of the two special administrative regions which are common law and Portuguese-based legal system jurisdictions respectively. This power is a legislative power and not a judicial one in that an interpretation by the NPCSC does not affect cases which have already been decided.

Question: What nation's model gives the power of the high court to the legistlature?
Ans:
Soviet Union
