The city ranked fourth for highest increase in the local technological innovation over the preceding 15 years, according to Forbes magazine. In the same year, the city ranked second on the annual Fortune 500 list of company headquarters, first for Forbes magazine's Best Cities for College Graduates, and first on their list of Best Cities to Buy a Home. In 2010, the city was rated the best city for shopping, according to Forbes.
Question: Where did Forbes magazine place Houston for technological innovation?

Output: fourth


QUES: Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. Light-emitting diodes are now used in applications as diverse as aviation lighting, automotive headlamps, advertising, general lighting, traffic signals, camera flashes and lighted wallpaper. As of 2015[update], LEDs powerful enough for room lighting remain somewhat more expensive, and require more precise current and heat management, than compact fluorescent lamp sources of comparable output.

What type of atmosphere can LED lighting be used?
What is the answer?
ANS: environmental


QUES: Some of these estimates also take into account the opportunity cost of investing capital many years before revenues are realized (see Time-value of money). Because of the very long time needed for discovery, development, and approval of pharmaceuticals, these costs can accumulate to nearly half the total expense. A direct consequence within the pharmaceutical industry value chain is that major pharmaceutical multinationals tend to increasingly outsource risks related to fundamental research, which somewhat reshapes the industry ecosystem with biotechnology companies playing an increasingly important role, and overall strategies being redefined accordingly. Some approved drugs, such as those based on re-formulation of an existing active ingredient (also referred to as Line-extensions) are much less expensive to develop.
What accounts for nearly half of the costs to develop companies?

ANS: unanswerable


Some historians argue that Napoleon III also sought war, particularly for the diplomatic defeat in 1866 in leveraging any benefits from the Austro-Prussian War, and he believed he would win a conflict with Prussia. They also argue that he wanted a war to resolve growing domestic political problems. Other historians, notably French historian Pierre Milza, dispute this. On 8 May 1870, shortly before the war, French voters had overwhelmingly supported Napoleon III's program in a national plebiscite, with 7,358,000 votes yes against 1,582,000 votes no, an increase of support of two million votes since the legislative elections in 1869. According to Milza, the Emperor had no need for a war to increase his popularity.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who proposed that Emperor needed no war to increase his public appeal?
Ah, so.. Milza


Question: With the discovery of fire, the earliest form of artificial lighting used to illuminate an area were campfires or torches. As early as 400,000 BCE, fire was kindled in the caves of Peking Man. Prehistoric people used primitive oil lamps to illuminate surroundings. These lamps were made from naturally occurring materials such as rocks, shells, horns and stones, were filled with grease, and had a fiber wick. Lamps typically used animal or vegetable fats as fuel. Hundreds of these lamps (hollow worked stones) have been found in the Lascaux caves in modern-day France, dating to about 15,000 years ago. Oily animals (birds and fish) were also used as lamps after being threaded with a wick. Fireflies have been used as lighting sources. Candles and glass and pottery lamps were also invented. Chandeliers were an early form of "light fixture".
Try to answer this question if possible: Peking man kindled fire as early as?
Answer: 400,000 BCE


Question: Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as the result of a Mars-sized object with about 10% of the Earth's mass impacting the planet in a glancing blow. Some of this object's mass merged with the Earth, significantly altering its internal composition, and a portion was ejected into space. Some of the material survived to form an orbiting moon. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered from comets, produced the oceans.
Try to answer this question if possible: What broke away a piece of the earth to form the moon?
Answer:
unanswerable
