Problem: Classical music:

The family of instruments used, especially in orchestras, grew. A wider array of percussion instruments began to appear. Brass instruments took on larger roles, as the introduction of rotary valves made it possible for them to play a wider range of notes. The size of the orchestra (typically around 40 in the Classical era) grew to be over 100. Gustav Mahler's 1906 Symphony No. 8, for example, has been performed with over 150 instrumentalists and choirs of over 400.

What array of instrument grew wider?

A: percussion

Problem: On 10 May 1963, John XXIII received the Balzan Prize in private at the Vatican but deflected achievements of himself to the five popes of his lifetime, Pope Leo XIII to Pius XII. On 11 May, the Italian President Antonio Segni officially awarded Pope John XXIII with the Balzan Prize for his engagement for peace. While in the car en route to the official ceremony, he suffered great stomach pains but insisted on meeting with Segni to receive the award in the Quirinal Palace, refusing to do so within the Vatican. He stated that it would have been an insult to honour a pontiff on the remains of the crucified Saint Peter. It was the pope's last public appearance.

Context and question: Copyright holders frequently refer to copyright infringement as theft. In copyright law, infringement does not refer to theft of physical objects that take away the owner's possession, but an instance where a person exercises one of the exclusive rights of the copyright holder without authorization. Courts have distinguished between copyright infringement and theft. For instance, the United States Supreme Court held in Dowling v. United States (1985) that bootleg phonorecords did not constitute stolen property. Instead, "interference with copyright does not easily equate with theft, conversion, or fraud. The Copyright Act even employs a separate term of art to define one who misappropriates a copyright: '[...] an infringer of the copyright.'" The court said that in the case of copyright infringement, the province guaranteed to the copyright holder by copyright law certain exclusive rights is invaded, but no control, physical or otherwise, is taken over the copyright, nor is the copyright holder wholly deprived of using the copyrighted work or exercising the exclusive rights held.
When you are accused theft as it relates to copyright law, you are exercising exclusive rights with what?
Answer: unanswerable

Question: By 1836, the Duchess's brother, Leopold, who had been King of the Belgians since 1831, hoped to marry his niece to his nephew, Prince Albert of Saxe-Coburg and Gotha. Leopold, Victoria's mother, and Albert's father (Ernest I, Duke of Saxe-Coburg and Gotha) were siblings. Leopold arranged for Victoria's mother to invite her Coburg relatives to visit her in May 1836, with the purpose of introducing Victoria to Albert. William IV, however, disapproved of any match with the Coburgs, and instead favoured the suit of Prince Alexander of the Netherlands, second son of the Prince of Orange. Victoria was aware of the various matrimonial plans and critically appraised a parade of eligible princes. According to her diary, she enjoyed Albert's company from the beginning. After the visit she wrote, "[Albert] is extremely handsome; his hair is about the same colour as mine; his eyes are large and blue, and he has a beautiful nose and a very sweet mouth with fine teeth; but the charm of his countenance is his expression, which is most delightful." Alexander, on the other hand, was "very plain".
Is there an answer to this question: Who disapproved of the proposed marriage between Victoria and Albert?

Answer: William IV

Question: Nintendo's near monopoly on the home video game market left it with a degree of influence over the industry. Unlike Atari, which never actively courted third-party developers (and even went to court in an attempt to force Activision to cease production of Atari 2600 games), Nintendo had anticipated and encouraged the involvement of third-party software developers; strictly, however, on Nintendo's terms. Some of the Nintendo platform-control measures were adopted by later console manufacturers such as Sega, Sony, and Microsoft, although not as stringent.
Is there an answer to this question: Nintendo's measures for third party game developers were also adopted by which later manufacturers?

Answer:
Sega, Sony, and Microsoft
