Problem: Some devices, such as high-speed external disk drives, require more than 500 mA of current and therefore may have power issues if powered from just one USB 2.0 port: erratic function, failure to function, or overloading/damaging the port. Such devices may come with an external power source or a Y-shaped cable that has two USB connectors (one for power and data, the other for power only) to plug into a computer. With such a cable, a device can draw power from two USB ports simultaneously. However, USB compliance specification states that "use of a 'Y' cable (a cable with two A-plugs) is prohibited on any USB peripheral", meaning that "if a USB peripheral requires more power than allowed by the USB specification to which it is designed, then it must be self-powered."
What is an example of a device that requires more than 500 mA of current?
The answer is the following: high-speed external disk drives

Problem: The 5th Regiment was sent to intercept him and made contact just south of Grenoble on March 7, 1815. Napoleon approached the regiment alone, dismounted his horse and, when he was within gunshot range, shouted to the soldiers, "Here I am. Kill your Emperor, if you wish." The soldiers quickly responded with, "Vive L'Empereur!" Ney, who had boasted to the restored Bourbon king, Louis XVIII, that he would bring Napoleon to Paris in an iron cage, affectionately kissed his former emperor and forgot his oath of allegiance to the Bourbon monarch. The two then marched together towards Paris with a growing army. The unpopular Louis XVIII fled to Belgium after realizing he had little political support. On March 13, the powers at the Congress of Vienna declared Napoleon an outlaw. Four days later, Great Britain, Russia, Austria, and Prussia each pledged to put 150,000 men into the field to end his rule.
What military unit was charged with intercepting Napoleon?
The answer is the following: The 5th Regiment

Problem: In general, German bombers were likely to get through to their targets without too much difficulty. It was to be some months before an effective night fighter force would be ready, and anti-aircraft defences only became adequate after the Blitz was over, so ruses were created to lure German bombers away from their targets. Throughout 1940, dummy airfields were prepared, good enough to stand up to skilled observation. A number[clarification needed] of bombs fell on these diversionary ("Starfish") targets.
Anti-aircraft defenses became better after what?
The answer is the following: Blitz was over

Problem: A standard dialect (also known as a standardized dialect or "standard language") is a dialect that is supported by institutions. Such institutional support may include government recognition or designation; presentation as being the "correct" form of a language in schools; published grammars, dictionaries, and textbooks that set forth a correct spoken and written form; and an extensive formal literature that employs that dialect (prose, poetry, non-fiction, etc.). There may be multiple standard dialects associated with a single language. For example, Standard American English, Standard British English, Standard Canadian English, Standard Indian English, Standard Australian English, and Standard Philippine English may all be said to be standard dialects of the English language.
The support of what groups results in a dialect being standardized?
The answer is the following:
institutions
