Here is a question about this article: When Emperor Kammu moved the capital to Heian-kyo (Kyoto), which remained the imperial capital for the next 1,000 years, he did so not only to strengthen imperial authority but also to improve his seat of government geopolitically. Nara was abandoned after only 70 years in part due to the ascendancy of Dokyo and the encroaching secular power of the Buddhist institutions there. Kyoto had good river access to the sea and could be reached by land routes from the eastern provinces. The early Heian period (784967) continued Nara culture; the Heian capital was patterned on the Chinese Tang capital at Chang'an, as was Nara, but on a larger scale than Nara. Kammu endeavoured to improve the Tang-style administrative system which was in use. Known as the ritsuryo, this system attempted to recreate the Tang imperium in Japan, despite the "tremendous differences in the levels of development between the two countries". Despite the decline of the Taika-Taiho reforms, imperial government was vigorous during the early Heian period. Indeed, Kammu's avoidance of drastic reform decreased the intensity of political struggles, and he became recognized as one of Japan's most forceful emperors.
What is the answer to this question: Nara was the former capital for how many years?

So... 70

Here is a question about this article: The 15th century was a time of Islamic economic expansion, known as the Valencian Golden Age, in which culture and the arts flourished. Concurrent population growth made Valencia the most populous city in the Crown of Aragon. Local industry, led by textile production, reached a great development, and a financial institution, the Canvi de Taula, was created to support municipal banking operations; Valencian bankers lent funds to Queen Isabella I of Castile for Columbus's voyage in 1492. At the end of the century the Silk Exchange (Llotja de la Seda) building was erected as the city became a commercial emporium that attracted merchants from all over Europe.
What is the answer to this question: What building attracted merchants from other countries to Valencia?

So... Silk Exchange

Here is a question about this article: Flower ontogeny uses a combination of genes normally responsible for forming new shoots. The most primitive flowers probably had a variable number of flower parts, often separate from (but in contact with) each other. The flowers tended to grow in a spiral pattern, to be bisexual (in plants, this means both male and female parts on the same flower), and to be dominated by the ovary (female part). As flowers evolved, some variations developed parts fused together, with a much more specific number and design, and with either specific sexes per flower or plant or at least "ovary-inferior".
What is the answer to this question: How did flowers become bixsexual?

So...
