Laurisilva is a unique type of subtropical rainforest found in few areas of Europe and the world: in the Azores, and in particular on the island of Madeira, there are large forests of endemic Laurisilva forests (the latter protected as a natural heritage preserve). There are several species of diverse mammalian fauna, including the fox, badger, iberian lynx, iberian wolf, wild goat (Capra pyrenaica), wild cat (Felis silvestris), hare, weasel, polecat, chameleon, mongoose, civet, brown bear[citation needed] (spotted near Rio Minho, close to Peneda-Geres) and many others. Portugal is an important stopover for migratory birds, in places such as Cape St. Vincent or the Monchique mountains, where thousands of birds cross from Europe to Africa during the autumn or in the spring (return migration).

What is Laurisilva?
Answer: a unique type of subtropical rainforest

Problem: In a switching circuit, the idea is to simulate, as near as possible, the ideal switch having the properties of open circuit when off, short circuit when on, and an instantaneous transition between the two states. Parameters are chosen such that the "off" output is limited to leakage currents too small to affect connected circuitry; the resistance of the transistor in the "on" state is too small to affect circuitry; and the transition between the two states is fast enough not to have a detrimental effect.
How quickly does the change from open circuit to short circuit happen?
The answer is the following: instantaneous

This format often includes dance-pop (such as upbeat songs by Madonna, Cher, Gloria Estefan and Kylie Minogue), power pops (mainly by boybands such as Backstreet Boys and Westlife), and adult-oriented soft rock music that are ballad-driven (typically by Aerosmith[citation needed], The Eagles, Sting, Toto and The Moody Blues). Generally, Hot AC radio stations target their music output towards the 18-54 age group and a demographic audience of both men and women.
What is the target age range of Hot AC stations?
18-54

Here is a question about this article: He moved rapidly. First, he promoted Confucian orthodoxy and reversed what he saw as his father's laxness by cracking down on unorthodox sects and by decapitating an anti-Manchu writer his father had pardoned. In 1723 he outlawed Christianity and expelled Christian missionaries, though some were allowed to remain in the capital. Next, he moved to control the government. He expanded his father's system of Palace Memorials which brought frank and detailed reports on local conditions directly to the throne without being intercepted by the bureaucracy, and created a small Grand Council of personal advisors which eventually grew into the emperor's de facto cabinet for the rest of the dynasty. He shrewdly filled key positions with Manchu and Han Chinese officials who depended on his patronage. When he began to realize that the financial crisis was even greater than he had thought, Yongzheng rejected his father's lenient approach to local landowning elites and mounted a campaign to enforce collection of the land tax. The increased revenues were to be used for "money to nourish honesty" among local officials and for local irrigation, schools, roads, and charity. Although these reforms were effective in the north, in the south and lower Yangzi valley, where Kangxi had wooed the elites, there were long established networks of officials and landowners. Yongzheng dispatched experienced Manchu commissioners to penetrate the thickets of falsified land registers and coded account books, but they were met with tricks, passivity, and even violence. The fiscal crisis persisted.
What is the answer to this question: When did Yongzheng ban christianity?
****
So...
1723
