Problem: Compaq, who had previously held the third place spot among PC manufacturers during the 1980s and early-mid 1990s, initiated a successful price war in 1994 that vaulted them to the biggest by the year end, overtaking a struggling IBM and relegating Apple to third place. Apple's market share further struggled due to the release of the Windows 95 operating system, which unified Microsoft's formerly separate MS-DOS and Windows products. Windows 95 significantly enhanced the multimedia capability and performance of IBM PC compatible computers, and brought the capabilities of Windows to parity with the Mac OS GUI.
Who did Compaq overtake in the price war of 1993?

On January 13, 1887, the U,S. Government moved to annul the patent issued to Bell on the grounds of fraud and misrepresentation. After a series of decisions and reversals, the Bell company won a decision in the Supreme Court, though a couple of the original claims from the lower court cases were left undecided. By the time that the trial wound its way through nine years of legal battles, the U.S. prosecuting attorney had died and the two Bell patents (No. 174,465 dated March 7, 1876 and No. 186,787 dated January 30, 1877) were no longer in effect, although the presiding judges agreed to continue the proceedings due to the case's importance as a "precedent". With a change in administration and charges of conflict of interest (on both sides) arising from the original trial, the US Attorney General dropped the lawsuit on November 30, 1897 leaving several issues undecided on the merits.
The US Government lost the bid to overturn Bell's patent in what court?
A: Supreme Court

Context and question: Diagnosis of infectious disease is nearly always initiated by medical history and physical examination. More detailed identification techniques involve the culture of infectious agents isolated from a patient. Culture allows identification of infectious organisms by examining their microscopic features, by detecting the presence of substances produced by pathogens, and by directly identifying an organism by its genotype. Other techniques (such as X-rays, CAT scans, PET scans or NMR) are used to produce images of internal abnormalities resulting from the growth of an infectious agent. The images are useful in detection of, for example, a bone abscess or a spongiform encephalopathy produced by a prion.
What can organisms be directly identified by?
Answer: its genotype

Question: The Aeronautics Branch was renamed the Bureau of Air Commerce in 1934 to reflect its enhanced status within the Department. As commercial flying increased, the Bureau encouraged a group of airlines to establish the first three centers for providing air traffic control (ATC) along the airways. In 1936, the Bureau itself took over the centers and began to expand the ATC system. The pioneer air traffic controllers used maps, blackboards, and mental calculations to ensure the safe separation of aircraft traveling along designated routes between cities.
Is there an answer to this question: What were the people who used maps, blackboards, and mental calculation to ensure the safe separation of aircraft traveling between cities called?

Answer: air traffic controllers

Many people from Strasbourg were incorporated in the German Army against their will, and were sent to the eastern front, those young men and women were called Malgre-nous. Many tried to escape from the incorporation, join the French Resistance, or desert the Wehrmacht but many couldn't because they were running the risk of having their families sent to work or concentration camps by the Germans. Many of these men, especially those who did not answer the call immediately, were pressured to "volunteer" for service with the SS, often by direct threats on their families. This threat obliged the majority of them to remain in the German army. After the war, the few that survived were often accused of being traitors or collaborationists, because this tough situation was not known in the rest of France, and they had to face the incomprehension of many. In July 1944, 1500 malgre-nous were released from Soviet captivity and sent to Algiers, where they joined the Free French Forces. Nowadays history recognizes the suffering of those people, and museums, public discussions and memorials have been built to commemorate this terrible period of history of this part of Eastern France (Alsace and Moselle). Liberation of Strasbourg took place on 23 November 1944.
How many Malgre-nous were able to desert the Wehrmacht?
A:
unanswerable
