Problem: Please answer a question about the following article about The Blitz:
In 1941, the Luftwaffe shifted strategy again. Erich Raeder—commander-in-chief of the Kriegsmarine—had long argued the Luftwaffe should support the German submarine force (U-Bootwaffe) in the Battle of the Atlantic by attacking shipping in the Atlantic Ocean and attacking British ports. Eventually, he convinced Hitler of the need to attack British port facilities. Hitler had been convinced by Raeder that this was the right course of action due to the high success rates of the U-Boat force during this period of the war. Hitler correctly noted that the greatest damage to the British war economy had been done through submarines and air attacks by small numbers of Focke-Wulf Fw 200 naval aircraft. He ordered attacks to be carried out on those targets which were also the target of the Kriegsmarine. This meant that British coastal centres and shipping at sea west of Ireland were the prime targets.
What did Erich Raeder believe the Luftwaffe needed to do?
A: support the German submarine force
Problem: Please answer a question about the following article about Macintosh:
Originally, the hardware architecture was so closely tied to the Mac OS operating system that it was impossible to boot an alternative operating system. The most common workaround, is to boot into Mac OS and then to hand over control to a Mac OS-based bootloader application. Used even by Apple for A/UX and MkLinux, this technique is no longer necessary since the introduction of Open Firmware-based PCI Macs, though it was formerly used for convenience on many Old World ROM systems due to bugs in the firmware implementation.[citation needed] Now, Mac hardware boots directly from Open Firmware in most PowerPC-based Macs or EFI in all Intel-based Macs.
Which technique was once used to boot an alternate operating system than Mac OS?
A: boot into Mac OS and then to hand over control to a Mac OS-based bootloader application
Problem: Please answer a question about the following article about Incandescent light bulb:
In 1902, the Siemens company developed a tantalum lamp filament. These lamps were more efficient than even graphitized carbon filaments and could operate at higher temperatures. Since tantalum metal has a lower resistivity than carbon, the tantalum lamp filament was quite long and required multiple internal supports. The metal filament had the property of gradually shortening in use; the filaments were installed with large loops that tightened in use. This made lamps in use for several hundred hours quite fragile. Metal filaments had the property of breaking and re-welding, though this would usually decrease resistance and shorten the life of the filament. General Electric bought the rights to use tantalum filaments and produced them in the US until 1913.
In what year was the tantalum light filament invented?
A: 1902
Problem: Please answer a question about the following article about Tajikistan:
Russian Imperialism led to the Russian Empire's conquest of Central Asia during the late 19th century's Imperial Era. Between 1864 and 1885 Russia gradually took control of the entire territory of Russian Turkestan, the Tajikistan portion of which had been controlled by the Emirate of Bukhara and Khanate of Kokand. Russia was interested in gaining access to a supply of cotton and in the 1870s attempted to switch cultivation in the region from grain to cotton (a strategy later copied and expanded by the Soviets).[citation needed] By 1885 Tajikistan's territory was either ruled by the Russian Empire or its vassal state, the Emirate of Bukhara, nevertheless Tajiks felt little Russian influence.[citation needed]
What did Russia do between 1864-1885?
A:
Russia gradually took control of the entire territory of Russian Turkestan
