Problem: Premier League:

Between the 1992–93 season and the 2012–13 season, Premier League clubs had won the UEFA Champions League four times (as well as supplying five of the runners-up), behind Spain's La Liga with six wins, and Italy's Serie A with five wins, and ahead of, among others, Germany's Bundesliga with three wins (see table here). The FIFA Club World Cup (or the FIFA Club World Championship, as it was originally called) has been won by Premier league clubs once (Manchester United in 2008), and they have also been runners-up twice, behind Brazil's Brasileirão with four wins, and Spain's La Liga and Italy's Serie A with two wins each (see table here).

Between 1992 and 2013, the Premier League won the UEFA Champions League four times and Germany's Bundesliga won how many times?

Problem: Some systems are capable of multipoint conferencing with no MCU, stand-alone, embedded or otherwise. These use a standards-based H.323 technique known as "decentralized multipoint", where each station in a multipoint call exchanges video and audio directly with the other stations with no central "manager" or other bottleneck. The advantages of this technique are that the video and audio will generally be of higher quality because they don't have to be relayed through a central point. Also, users can make ad-hoc multipoint calls without any concern for the availability or control of an MCU. This added convenience and quality comes at the expense of some increased network bandwidth, because every station must transmit to every other station directly.
What do systems that use an MCU, use for video conferencing?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Beer contains ethyl alcohol, the same chemical that is present in wine and distilled spirits and as such, beer consumption has short-term psychological and physiological effects on the user. Different concentrations of alcohol in the human body have different effects on a person. The effects of alcohol depend on the amount an individual has drunk, the percentage of alcohol in the beer and the timespan that the consumption took place, the amount of food eaten and whether an individual has taken other prescription, over-the-counter or street drugs, among other factors. Drinking enough to cause a blood alcohol concentration (BAC) of 0.03%-0.12% typically causes an overall improvement in mood and possible euphoria, increased self-confidence and sociability, decreased anxiety, a flushed, red appearance in the face and impaired judgment and fine muscle coordination. A BAC of 0.09% to 0.25% causes lethargy, sedation, balance problems and blurred vision. A BAC from 0.18% to 0.30% causes profound confusion, impaired speech (e.g., slurred speech), staggering, dizziness and vomiting. A BAC from 0.25% to 0.40% causes stupor, unconsciousness, anterograde amnesia, vomiting (death may occur due to inhalation of vomit (pulmonary aspiration) while unconscious and respiratory depression (potentially life-threatening). A BAC from 0.35% to 0.80% causes a coma (unconsciousness), life-threatening respiratory depression and possibly fatal alcohol poisoning. As with all alcoholic drinks, drinking while driving, operating an aircraft or heavy machinery increases the risk of an accident; many countries have penalties against drunk driving.
How is alcohol measured in the human body?
A: blood alcohol concentration


Context and question: In electric power distribution, capacitors are used for power factor correction. Such capacitors often come as three capacitors connected as a three phase load. Usually, the values of these capacitors are given not in farads but rather as a reactive power in volt-amperes reactive (var). The purpose is to counteract inductive loading from devices like electric motors and transmission lines to make the load appear to be mostly resistive. Individual motor or lamp loads may have capacitors for power factor correction, or larger sets of capacitors (usually with automatic switching devices) may be installed at a load center within a building or in a large utility substation.
 How are capacitors never used for power factor correction prepared?
Answer: unanswerable


Question: The European Central Bank had stepped up the buying of member nations debt. In response to the crisis of 2010, some proposals have surfaced for a collective European bond issue that would allow the central bank to purchase a European version of US Treasury bills. To make European sovereign debt assets more similar to a US Treasury, a collective guarantee of the member states' solvency would be necessary.[b] But the German government has resisted this proposal, and other analyses indicate that "the sickness of the euro" is due to the linkage between sovereign debt and failing national banking systems. If the European central bank were to deal directly with failing banking systems sovereign debt would not look as leveraged relative to national income in the financially weaker member states.
Is there an answer to this question: What would have to happen to make European sovereign debt assets more like what is found in the U.S. Treasury?

Answer: a collective guarantee of the member states' solvency


QUES: Updated Motorola CPUs made a faster machine possible, and in 1987 Apple took advantage of the new Motorola technology and introduced the Macintosh II at $5500, powered by a 16 MHz Motorola 68020 processor. The primary improvement in the Macintosh II was Color QuickDraw in ROM, a color version of the graphics language which was the heart of the machine. Among the many innovations in Color QuickDraw were the ability to handle any display size, any color depth, and multiple monitors. The Macintosh II marked the start of a new direction for the Macintosh, as now for the first time it had an open architecture with several NuBus expansion slots, support for color graphics and external monitors, and a modular design similar to that of the IBM PC. It had an internal hard drive and a power supply with a fan, which was initially fairly loud. One third-party developer sold a device to regulate fan speed based on a heat sensor, but it voided the warranty. Later Macintosh computers had quieter power supplies and hard drives.
