Problem: Northwestern University:

In Fall 2008, Northwestern opened a campus in Education City, Doha, Qatar, joining five other American universities: Carnegie Mellon University, Cornell University, Georgetown University, Texas A&M University, and Virginia Commonwealth University. Through the Medill School of Journalism and School of Communication, NU-Q offers bachelor's degrees in journalism and communication respectively. The Qatar Foundation for Education, Science and Community Development provided funding for construction and administrative costs as well as support to hire 50 to 60 faculty and staff, some of whom rotate between the Evanston and Qatar campuses. In February 2016, Northwestern reached an agreement with the Qatar Foundation to extend the operations of the NU-Q branch for an additional decade, through the 2027-2028 academic year.

Problem: Kerry established a separate political action committee, Keeping America's Promise, which declared as its mandate "A Democratic Congress will restore accountability to Washington and help change a disastrous course in Iraq", and raised money and channeled contributions to Democratic candidates in state and federal races. Through Keeping America's Promise in 2005, Kerry raised over $5.5 million for other Democrats up and down the ballot. Through his campaign account and his political action committee, the Kerry campaign operation generated more than $10 million for various party committees and 179 candidates for the U.S. House, Senate, state and local offices in 42 states focusing on the midterm elections during the 2006 election cycle. "Cumulatively, John Kerry has done as much if not more than any other individual senator", Hassan Nemazee, the national finance chairman of the DSCC said.

Context and question: The colloquialism "buck"(s) (much like the British word "quid"(s, pl) for the pound sterling) is often used to refer to dollars of various nations, including the U.S. dollar. This term, dating to the 18th century, may have originated with the colonial leather trade. It may also have originated from a poker term. "Greenback" is another nickname originally applied specifically to the 19th century Demand Note dollars created by Abraham Lincoln to finance the costs of the Civil War for the North. The original note was printed in black and green on the back side. It is still used to refer to the U.S. dollar (but not to the dollars of other countries). Other well-known names of the dollar as a whole in denominations include "greenmail", "green" and "dead presidents" (the last because deceased presidents are pictured on most bills).
What was the nickname given to the Demand Bill dollars that were used to finance the buck?
Answer: unanswerable

Question: The Hanoverian king George II of Great Britain was passionately devoted to his family's continental holdings, but his commitments in Germany were counterbalanced by the demands of the British colonies overseas. If war against France for colonial expansion was to be resumed, then Hanover had to be secured against Franco-Prussian attack. France was very much interested in colonial expansion and was willing to exploit the vulnerability of Hanover in war against Great Britain, but it had no desire to divert forces to central Europe for Prussia's interest.
Is there an answer to this question: How anxious was France to assist Prussia to take over Hanover?

Answer: it had no desire to divert forces to central Europe for Prussia's interest.

Problem: Copper:

Alloying copper with tin to make bronze was first practiced about 4000 years after the discovery of copper smelting, and about 2000 years after "natural bronze" had come into general use[citation needed]. Bronze artifacts from the Vinca culture date to 4500 BC. Sumerian and Egyptian artifacts of copper and bronze alloys date to 3000 BC. The Bronze Age began in Southeastern Europe around 37003300 BC, in Northwestern Europe about 2500 BC. It ended with the beginning of the Iron Age, 20001000 BC in the Near East, 600 BC in Northern Europe. The transition between the Neolithic period and the Bronze Age was formerly termed the Chalcolithic period (copper-stone), with copper tools being used with stone tools. This term has gradually fallen out of favor because in some parts of the world the Chalcolithic and Neolithic are coterminous at both ends. Brass, an alloy of copper and zinc, is of much more recent origin. It was known to the Greeks, but became a significant supplement to bronze during the Roman Empire.

What are the first datings of Bronze artifacts from the Vinca culture?
