Problem: Windows 8 introduces significant changes to the operating system's user interface, many of which are aimed at improving its experience on tablet computers and other touchscreen devices. The new user interface is based on Microsoft's Metro design language, and uses a Start screen similar to that of Windows Phone 7 as the primary means of launching applications. The Start screen displays a customizable array of tiles linking to various apps and desktop programs, some of which can display constantly updated information and content through "live tiles". As a form of multi-tasking, apps can be snapped to the side of a screen. Alongside the traditional Control Panel, a new simplified and touch-optimized settings app known as "PC Settings" is used for basic configuration and user settings. It does not include many of the advanced options still accessible from the normal Control Panel.
What is the primary function of the PC Settings app?
The answer is the following: used for basic configuration and user settings

Problem: On 14 January 1858, an Italian refugee from Britain called Orsini attempted to assassinate Napoleon III with a bomb made in England. The ensuing diplomatic crisis destabilised the government, and Palmerston resigned. Derby was reinstated as prime minister. Victoria and Albert attended the opening of a new basin at the French military port of Cherbourg on 5 August 1858, in an attempt by Napoleon III to reassure Britain that his military preparations were directed elsewhere. On her return Victoria wrote to Derby reprimanding him for the poor state of the Royal Navy in comparison to the French one. Derby's ministry did not last long, and in June 1859 Victoria recalled Palmerston to office.
Where did Victoria visit that led her to reprimand Derby for the state of the Royal Navy?
The answer is the following: French military port of Cherbourg

Problem: 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.
How long after the National Academy of Science's study did a study on over the counter drugs occur?
The answer is the following: ten years later

Problem: Performers who have studied classical music extensively are said to be "classically trained". This training may be from private lessons from instrument or voice teachers or from completion of a formal program offered by a Conservatory, college or university, such as a B.mus. or M.mus. degree (which includes individual lessons from professors). In classical music, "...extensive formal music education and training, often to postgraduate [Master's degree] level" is required.
To what level is training for classical music often required?
The answer is the following:
postgraduate
