Problem: Sino-Tibetan relations during the Ming dynasty:

China Daily, a CCP-controlled news organization since 1981, states in a 2008 article that although there were dynastic changes after Tibet was incorporated into the territory of Yuan dynasty's China in the 13th century, "Tibet has remained under the jurisdiction of the central government of China." It also states that the Ming dynasty "inherited the right to rule Tibet" from the Yuan dynasty, and repeats the claims in the Mingshi about the Ming establishing two itinerant high commands over Tibet. China Daily states that the Ming handled Tibet's civil administration, appointed all leading officials of these administrative organs, and punished Tibetans who broke the law. The party-controlled People's Daily, the state-controlled Xinhua News Agency, and the state-controlled national television network China Central Television posted the same article that China Daily had, the only difference being their headlines and some additional text.

According to article Tibet has remained under what jurisdiction?

Problem: Russian Soviet Federative Socialist Republic:

On January 25, 1918 the third meeting of the All-Russian Congress of Soviets renamed the unrecognized state the Soviet Russian Republic. The Treaty of Brest-Litovsk was signed on March 3, 1918, giving away much of the land of the former Russian Empire to Germany in exchange for peace during the rest of World War I. On July 10, 1918, the Russian Constitution of 1918 renamed the country the Russian Socialist Federative Soviet Republic. By 1918, during the Russian Civil War, several states within the former Russian Empire seceded, reducing the size of the country even more.

The Treaty of Brest-Litovsk ceded land to what state?
---
A: Germany

Problem: Infrared:

Near-infrared is the region closest in wavelength to the radiation detectable by the human eye, mid- and far-infrared are progressively further from the visible spectrum. Other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (the common silicon detectors are sensitive to about 1,050 nm, while InGaAs's sensitivity starts around 950 nm and ends between 1,700 and 2,600 nm, depending on the specific configuration). Unfortunately, international standards for these specifications are not currently available.

What InGaAs is progressively further from the visible spectrum for the human eye?

A: unanswerable

Problem: Frederic Chopin:

At the age of 21 he settled in Paris. Thereafter, during the last 18 years of his life, he gave only some 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and teaching piano, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his musical contemporaries, including Robert Schumann. In 1835 he obtained French citizenship. After a failed engagement to Maria Wodzinska, from 1837 to 1847 he maintained an often troubled relationship with the French writer George Sand. A brief and unhappy visit to Majorca with Sand in 183839 was one of his most productive periods of composition. In his last years, he was financially supported by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. Through most of his life, Chopin suffered from poor health. He died in Paris in 1849, probably of tuberculosis.

In the last years of his life who was the person that supported him financially?

A:
Jane Stirling
