Question: Alpine crystals have been studied and collected for hundreds of years, and began to be classified in the 18th century. Leonhard Euler studied the shapes of crystals, and by the 19th century crystal hunting was common in Alpine regions. David Friedrich Wiser amassed a collection of 8000 crystals that he studied and documented. In the 20th century Robert Parker wrote a well-known work about the rock crystals of the Swiss Alps; at the same period a commission was established to control and standardize the naming of Alpine minerals.
Try to answer this question if possible: Who studied the shapes of crystals? 
Answer: Leonhard Euler
Question: The principal official languages (German, French, and Italian) have terms, not used outside of Switzerland, known as Helvetisms. German Helvetisms are, roughly speaking, a large group of words typical of Swiss Standard German, which do not appear either in Standard German, nor in other German dialects. These include terms from Switzerland's surrounding language cultures (German Billette from French), from similar term in another language (Italian azione used not only as act but also as discount from German Aktion). The French spoken in Switzerland has similar terms, which are equally known as Helvetisms. The most frequent characteristics of Helvetisms are in vocabulary, phrases, and pronunciation, but certain Helvetisms denote themselves as special in syntax and orthography likewise. Duden, one of the prescriptive sources for Standard German, is aware of about 3000 Helvetisms. Current French dictionaries, such as the Petit Larousse, include several hundred Helvetisms.

Question: Dell became the first company in the information technology industry to establish a product-recycling goal (in 2004) and completed the implementation of its global consumer recycling-program in 2006. On February 6, 2007, the National Recycling Coalition awarded Dell its "Recycling Works" award for efforts to promote producer responsibility. On July 19, 2007, Dell announced that it had exceeded targets in working to achieve a multi-year goal of recovering 275 million pounds of computer equipment by 2009. The company reported the recovery of 78 million pounds (nearly 40,000 tons) of IT equipment from customers in 2006, a 93-percent increase over 2005; and 12.4% of the equipment Dell sold seven years earlier.
Try to answer this question if possible: What percentage of Dell electronics from the previous six years were recycled?
Answer: unanswerable
Question: Burke was not merely presenting a peace agreement to Parliament; rather, he stepped forward with four reasons against using force, carefully reasoned. He laid out his objections in an orderly manner, focusing on one before moving to the next. His first concern was that the use of force would have to be temporary, and that the uprisings and objections to British governance in America would not be. Second, Burke worried about the uncertainty surrounding whether Britain would win a conflict in America. "An armament", Burke said, "is not a victory". Third, Burke brought up the issue of impairment; it would do the British Government no good to engage in a scorched earth war and have the object they desired (America) become damaged or even useless. The American colonists could always retreat into the mountains, but the land they left behind would most likely be unusable, whether by accident or design. The fourth and final reason to avoid the use of force was experience; the British had never attempted to rein in an unruly colony by force, and they did not know if it could be done, let alone accomplished thousands of miles away from home. Not only were all of these concerns reasonable, but some turned out to be prophetic – the American colonists did not surrender, even when things looked extremely bleak, and the British were ultimately unsuccessful in their attempts to win a war fought on American soil.
