Here is a question about this article: Early releases of the Washington coin included error coins shipped primarily from the Philadelphia mint to Florida and Tennessee banks. Highly sought after by collectors, and trading for as much as $850 each within a week of discovery, the error coins were identified by the absence of the edge impressions "E PLURIBUS UNUM IN GOD WE TRUST 2007 P". The mint of origin is generally accepted to be mostly Philadelphia, although identifying the source mint is impossible without opening a mint pack also containing marked units. Edge lettering is minted in both orientations with respect to "heads", some amateur collectors were initially duped into buying "upside down lettering error" coins. Some cynics also erroneously point out that the Federal Reserve makes more profit from dollar bills than dollar coins because they wear out in a few years, whereas coins are more permanent. The fallacy of this argument arises because new notes printed to replace worn out notes, which have been withdrawn from circulation, bring in no net revenue to the government to offset the costs of printing new notes and destroying the old ones. As most vending machines are incapable of making change in banknotes, they commonly accept only $1 bills, though a few will give change in dollar coins.
What is the answer to this question: What were some amateur collectors duped into buying?
****
So... "upside down lettering error" coins

The problem: Answer a question about this article:
The dictatorship of Franco forbade political parties and began a harsh ideological and cultural repression countenanced and sometimes even led by the Church. The financial markets were destabilised, causing a severe economic crisis that led to rationing. A black market in rationed goods existed for over a decade. The Francoist administrations of Valencia silenced publicity of the catastrophic consequences of the floods of 1949 with the attendant dozens of deaths, but could not do the same after the even more tragic flood of 1957 when the river Turia overflowed its banks again, killing many Valencians (officially, eighty-one died; the actual figure is not known). To prevent further disasters, the river was eventually diverted to a new course. The old river bed was abandoned for years, and successive Francoist mayors proposed making it a motorway, but that option was finally rejected with the advent of democracy and fervent neighbourhood protests. The river was divided in two at the western city limits (Plan Sur de Valencia), and diverted southwards along a new course that skirts the city, before meeting the Mediterranean. The old course of the river continues, dry, through the city centre, almost to the sea. The old riverbed is now a verdant sunken park called the 'Garden of the Turia' (Jardi del Turia or Jardin del Turia) that allows cyclists and pedestrians to traverse much of the city without the use of roads; overhead bridges carry motor traffic across the park.
What river flooded in 1957?
****
The answer: Turia

Problem: Please answer a question about the following article about New Haven, Connecticut:
After the American Revolutionary War broke out in 1776, the Connecticut colonial government ordered the construction of Black Rock Fort (to be built on top of an older 17th-century fort) to protect the port of New Haven. In 1779, during the Battle of New Haven, British soldiers captured Black Rock Fort and burned the barracks to the ground. The fort was reconstructed in 1807 by the federal government (on orders from the Thomas Jefferson administration), and rechristened Fort Nathan Hale, after the Revolutionary War hero who had lived in New Haven. The cannons of Fort Nathan Hale were successful in defying British war ships during the War of 1812. In 1863, during the Civil War, a second Fort Hale was built next to the original, complete with bomb-resistant bunkers and a moat, to defend the city should a Southern raid against New Haven be launched. The United States Congress deeded the site to the state in 1921, and all three versions of the fort have been restored. The site is now listed on the National Register of Historic Places and receives thousands of visitors each year.
What two fortifications distinguished the second Fort Hale built in New Haven during the Civil War?
A: bomb-resistant bunkers and a moat

Stereophonic sound recording, which attempts to provide a more natural listening experience by reproducing the spatial locations of sound sources in the horizontal plane, was the natural extension to monophonic recording, and attracted various alternative engineering attempts. The ultimately dominant "45/45" stereophonic record system was invented by Alan Blumlein of EMI in 1931 and patented the same year. EMI cut the first stereo test discs using the system in 1933 (see Bell Labs Stereo Experiments of 1933) although the system was not exploited commercially until much later.

What year was stereo sound patented?
Answer: 1931
