Question: In 2006, FIG introduced a new points system for Artistic gymnastics in which scores are no longer limited to 10 points. The system is used in the US for elite level competition. Unlike the old code of points, there are two separate scores, an execution score and a difficulty score. In the previous system, the "execution score" was the only score. It was and still is out of 10.00. During the gymnast's performance, the judges deduct this score only. A fall, on or off the event, is a 1.00 deduction, in elite level gymnastics. The introduction of the difficulty score is a significant change. The gymnast's difficulty score is based on what elements they perform and is subject to change if they do not perform or complete all the skills, or they do not connect a skill meant to be connected to another. Connection bonuses are the most common deduction from a difficulty score, as it can be difficult to connect multiple flight elements. It is very hard to connect skills if the first skill is not performed correctly. The new code of points allows the gymnasts to gain higher scores based on the difficulty of the skills they perform as well as their execution. There is no maximum score for difficulty, as it can keep increasing as the difficulty of the skills increase.

Answer: an execution score and a difficulty score
Question: A watt balance is an instrument for comparing two powers, one of which is measured in SI watts and the other of which is measured in conventional electrical units. From the definition of the conventional watt W90, this gives a measure of the product KJ2RK in SI units, where RK is the von Klitzing constant which appears in the quantum Hall effect. If the theoretical treatments of the Josephson effect and the quantum Hall effect are valid, and in particular assuming that RK = h/e2, the measurement of KJ2RK is a direct determination of the Planck constant.

Question: The Classical era, from about 1750 to 1820, established many of the norms of composition, presentation, and style, and was also when the piano became the predominant keyboard instrument. The basic forces required for an orchestra became somewhat standardized (although they would grow as the potential of a wider array of instruments was developed in the following centuries). Chamber music grew to include ensembles with as many as 8 to 10 performers for serenades. Opera continued to develop, with regional styles in Italy, France, and German-speaking lands. The opera buffa, a form of comic opera, rose in popularity. The symphony came into its own as a musical form, and the concerto was developed as a vehicle for displays of virtuoso playing skill. Orchestras no longer required a harpsichord (which had been part of the traditional continuo in the Baroque style), and were often led by the lead violinist (now called the concertmaster).

Answer: the piano
Question: Following the 1914–15 edition, the competition was suspended due to the First World War, and didn't resume until 1919–20. The 1922–23 competition saw the first final to be played in the newly opened Wembley Stadium (known at the time as the Empire Stadium). Due to the outbreak of World War II, the competition wasn't played between the 1938–39 and 1945–46 editions. Due to the wartime breaks, the competition didn't celebrate its centenary year until 1980–81; fittingly the final featured a goal by Ricky Villa which was later voted the greatest goal ever scored at Wembley Stadium, but has since been replaced by Steven Gerrard.
