Here is a question about this article: In 1368, a Han Chinese revolt known as the Red Turban Rebellion toppled the Mongol Yuan dynasty in China. Zhu Yuanzhang then established the Ming dynasty, ruling as the Hongwu Emperor (r. 1368–1398). It is not clear how much the early Ming court understood the civil war going on in Tibet between rival religious sects, but the first emperor was anxious to avoid the same trouble that Tibet had caused for the Tang dynasty. Instead of recognizing the Phagmodru ruler, the Hongwu Emperor sided with the Karmapa of the nearer Kham region and southeastern Tibet, sending envoys out in the winter of 1372–1373 to ask the Yuan officeholders to renew their titles for the new Ming court.
What is the answer to this question: What years did Zhu Yuanzhang rule as the Hongwu Emperor?

So... 1368–1398


Here is a question about this article: In the last years of the nineteenth century, Planck was investigating the problem of black-body radiation first posed by Kirchhoff some forty years earlier. It is well known that hot objects glow, and that hotter objects glow brighter than cooler ones. The electromagnetic field obeys laws of motion similarly to a mass on a spring, and can come to thermal equilibrium with hot atoms. The hot object in equilibrium with light absorbs just as much light as it emits. If the object is black, meaning it absorbs all the light that hits it, then its thermal light emission is maximized.
What is the answer to this question: Who posed the problem of black-body radiation?

So... Kirchhoff


Here is a question about this article: Southern Europe's most emblematic climate is that of the Mediterranean climate, which has become a typically known characteristic of the area. The Mediterranean climate covers much of Portugal, Spain, Southeast France, Italy, Croatia, Albania, Montenegro, Greece, the Western and Southern coastal regions of Turkey as well as the Mediterranean islands. Those areas of Mediterranean climate present similar vegetations and landscapes throughout, including dry hills, small plains, pine forests and olive trees.
What is the answer to this question: What kind of climate is exemplary of southern Europe?

So...
The Mediterranean climate
