[Q]: Extract the answer to the question from the following context. Question: What microsoft product is MTP used for? Context: Media Transfer Protocol (MTP) was designed by Microsoft to give higher-level access to a device's filesystem than USB mass storage, at the level of files rather than disk blocks. It also has optional DRM features. MTP was designed for use with portable media players, but it has since been adopted as the primary storage access protocol of the Android operating system from the version 4.1 Jelly Bean as well as Windows Phone 8 (Windows Phone 7 devices had used the Zune protocol which was an evolution of MTP). The primary reason for this is that MTP does not require exclusive access to the storage device the way UMS does, alleviating potential problems should an Android program request the storage while it is attached to a computer. The main drawback is that MTP is not as well supported outside of Windows operating systems.

[Q]: Extract the answer to the question from the following context. Question: What did the aggressor do? Context: The Russians sent a fleet to Sinop in northern Anatolia. In the Battle of Sinop on 30 November 1853 they destroyed a patrol squadron of Ottoman frigates and corvettes while they were anchored in port. Public opinion in the UK and France was outraged and demanded war. Sinop provided the United Kingdom and France with the casus belli ("cause for war") for declaring war against Russia. On 28 March 1854, after Russia ignored an Anglo-French ultimatum to withdraw from the Danubian Principalities, the UK and France formally declared war.

[Q]: Extract the answer to the question from the following context. Question: What was the bottom cutoff for introduced drugs that were required by law to be effective? Context: The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.
