Problem: In London Chopin took lodgings at Dover Street, where the firm of Broadwood provided him with a grand piano. At his first engagement, on 15 May at Stafford House, the audience included Queen Victoria and Prince Albert. The Prince, who was himself a talented musician, moved close to the keyboard to view Chopin's technique. Broadwood also arranged concerts for him; among those attending were Thackeray and the singer Jenny Lind. Chopin was also sought after for piano lessons, for which he charged the high fee of one guinea (1.05 in present British currency) per hour, and for private recitals for which the fee was 20 guineas. At a concert on 7 July he shared the platform with Viardot, who sang arrangements of some of his mazurkas to Spanish texts.

Problem: Much of YouTube's revenue goes to the copyright holders of the videos. In 2010 it was reported that nearly a third of the videos with advertisements were uploaded without permission of the copyright holders.

In May 2013, Nintendo began enforcing its copyright ownership and claiming the advertising revenue from video creators who posted screenshots of its games. In February 2015, Nintendo agreed to share the revenue with the video creators.
What option besides removing the video does youtube grant copyright holders?

Problem: In 1920, Turkish nationalist forces invaded the fledgling Armenian republic from the east. Turkish forces under the command of Kazm Karabekir captured Armenian territories that Russia had annexed in the aftermath of the 18771878 Russo-Turkish War and occupied the old city of Alexandropol (present-day Gyumri). The violent conflict finally concluded with the Treaty of Alexandropol on 2 December 1920. The treaty forced Armenia to disarm most of its military forces, cede all former Ottoman territory granted to it by the Treaty of Sevres, and to give up all the "Wilsonian Armenia" granted to it at the Sevres treaty. Simultaneously, the Soviet Eleventh Army, under the command of Grigoriy Ordzhonikidze, invaded Armenia at Karavansarai (present-day Ijevan) on 29 November. By 4 December, Ordzhonikidze's forces entered Yerevan and the short-lived Armenian republic collapsed.
What year did Turkish nationalists seize the Armenian Republic?
The answer is the following:
1920
