QUES: On 16 March 1934, President Franklin D. Roosevelt signed the Migratory Bird Hunting Stamp Act, which requires an annual stamp purchase by all hunters over the age of sixteen. The stamps are created on behalf of the program by the US Postal Service and depict wildlife artwork chosen through an annual contest. They play an important role in habitat conservation because ninety-eight percent of all funds generated by their sale go directly toward the purchase or lease of wetland habitat for protection in the National Wildlife Refuge System.[citation needed] In addition to waterfowl, it is estimated that one third of the nation's endangered species seek food and shelter in areas protected using Duck Stamp funds.[citation needed]
How much of the nation's endangered species is it estimated benefits from the protection afford by the Duck Stamp funds?

ANS: one third

QUES: The Chicago Cubs have not won a World Series championship since 1908, and have not appeared in the Fall Classic since 1945, although between their postseason appearance in 1984 and their most recent in 2015, they have made the postseason seven times. 107 seasons is the longest championship drought in all four of the major North American professional sports leagues, which also includes the National Football League (NFL), the National Basketball Association (NBA), and the National Hockey League (NHL). In fact, the Cubs' last World Series title occurred before those other three leagues even existed, and even the Cubs' last World Series appearance predates the founding of the NBA. The much publicized drought was concurrent to championship droughts by the Boston Red Sox and the Chicago White Sox, who both had over 80 years between championships. It is this unfortunate distinction that has led to the club often being known as "The Lovable Losers." The team was one win away from breaking what is often called the "Curse of the Billy Goat" in 1984 and 2003 (Steve Bartman incident), but was unable get the victory that would send it to the World Series.
What is the longest championship drought in all four of the major North American professional sports leagues?

QUES: In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal from aes yprium (metal of Cyprus), later corrupted to uprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite, malachite and turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and in the form of pigments.
