QUES: The foundations of the British Empire were laid when England and Scotland were separate kingdoms. In 1496 King Henry VII of England, following the successes of Spain and Portugal in overseas exploration, commissioned John Cabot to lead a voyage to discover a route to Asia via the North Atlantic. Cabot sailed in 1497, five years after the European discovery of America, and although he successfully made landfall on the coast of Newfoundland (mistakenly believing, like Christopher Columbus, that he had reached Asia), there was no attempt to found a colony. Cabot led another voyage to the Americas the following year but nothing was heard of his ships again.
When was John Cabot's voyage commissioned?

ANS: 1496

The late nineteenth century also brought the systematic study of color theory, and particularly the study of how complementary colors such as red and green reinforced each other when they were placed next to each other. These studies were avidly followed by artists such as Vincent van Gogh. Describing his painting, The Night Cafe, to his brother Theo in 1888, Van Gogh wrote: "I sought to express with red and green the terrible human passions. The hall is blood red and pale yellow, with a green billiard table in the center, and four lamps of lemon yellow, with rays of orange and green. Everywhere it is a battle and antithesis of the most different reds and greens."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What year did color theory first appear?
Ah, so.. unanswerable

QUES: The areas that are not arid and receive high precipitation experience periodic flooding from rapid snowmelt and runoff. The mean precipitation in the Alps ranges from a low of 2,600 mm (100 in) per year to 3,600 mm (140 in) per year, with the higher levels occurring at high altitudes. At altitudes between 1,000 and 3,000 m (3,281 and 9,843 ft), snowfall begins in November and accumulates through to April or May when the melt begins. Snow lines vary from 2,400 to 3,000 m (7,874 to 9,843 ft), above which the snow is permanent and the temperatures hover around the freezing point even July and August. High-water levels in streams and rivers peak in June and July when the snow is still melting at the higher altitudes.
At what altitude does snowfall begin in November?

ANS:
At altitudes between 1,000 and 3,000 m
