Problem: United States presidential election, 2004:

During August and September 2004, there was an intense focus on events that occurred in the late 1960s and early 1970s. Bush was accused of failing to fulfill his required service in the Texas Air National Guard. However, the focus quickly shifted to the conduct of CBS News after they aired a segment on 60 Minutes Wednesday introducing what became known as the Killian documents. Serious doubts about the documents' authenticity quickly emerged, leading CBS to appoint a review panel that eventually resulted in the firing of the news producer and other significant staffing changes.

Which time period came into the spotlight, during the fall of 2004?

A: the late 1960s and early 1970s

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Unlike the Spanish milled dollar the U.S. dollar is based upon a decimal system of values. In addition to the dollar the coinage act officially established monetary units of mill or one-thousandth of a dollar (symbol ), cent or one-hundredth of a dollar (symbol ), dime or one-tenth of a dollar, and eagle or ten dollars, with prescribed weights and composition of gold, silver, or copper for each. It was proposed in the mid-1800s that one hundred dollars be known as a union, but no union coins were ever struck and only patterns for the $50 half union exist. However, only cents are in everyday use as divisions of the dollar; "dime" is used solely as the name of the coin with the value of 10, while "eagle" and "mill" are largely unknown to the general public, though mills are sometimes used in matters of tax levies, and gasoline prices are usually in the form of $X.XX9 per gallon, e.g., $3.599, sometimes written as $3.59910. When currently issued in circulating form, denominations equal to or less than a dollar are emitted as U.S. coins while denominations equal to or greater than a dollar are emitted as Federal Reserve notes (with the exception of gold, silver and platinum coins valued up to $100 as legal tender, but worth far more as bullion). Both one-dollar coins and notes are produced today, although the note form is significantly more common. In the past, "paper money" was occasionally issued in denominations less than a dollar (fractional currency) and gold coins were issued for circulation up to the value of $20 (known as the "double eagle", discontinued in the 1930s). The term eagle was used in the Coinage Act of 1792 for the denomination of ten dollars, and subsequently was used in naming gold coins. Paper currency less than one dollar in denomination, known as "fractional currency", was also sometimes pejoratively referred to as "shinplasters". In 1854, James Guthrie, then Secretary of the Treasury, proposed creating $100, $50 and $25 gold coins, which were referred to as a "Union", "Half Union", and "Quarter Union", thus implying a denomination of 1 Union = $100.
How much monetary value does a treasury hold?
A: unanswerable

Context and question: On 20 February 2001, the bureau announced that a special agent, Robert Hanssen (born 1944) had been arrested for spying for the Soviet Union and then Russia from 1979 to 2001. He is serving 15 consecutive life sentences without the possibility of parole at ADX Florence, a federal supermax prison near Florence, Colorado. Hanssen was arrested on February 18, 2001 at Foxstone Park near his home in Vienna, Virginia, and was charged with selling US secrets to the USSR and subsequently Russia for more than US$1.4 million in cash and diamonds over a 22-year period. On July 6, 2001, he pleaded guilty to 15 counts of espionage in the United States District Court for the Eastern District of Virginia. His spying activities have been described by the US Department of Justice's Commission for the Review of FBI Security Programs as "possibly the worst intelligence disaster in U.S. history".
How much did the FBI pay Hanssen to spy on Russia?
Answer: unanswerable

Question: On July 6, John Kerry selected John Edwards as his running mate, shortly before the 2004 Democratic National Convention in Boston, held later that month. Days before Kerry announced Edwards as his running mate, Kerry gave a short list of three candidates: Sen John Edwards, Rep Dick Gephardt, and Gov Tom Vilsack. Heading into the convention, the Kerry/Edwards ticket unveiled their new slogana promise to make America "stronger at home and more respected in the world." Kerry made his Vietnam War experience the prominent theme of the convention. In accepting the nomination, he began his speech with, "I'm John Kerry and I'm reporting for duty." He later delivered what may have been the speech's most memorable line when he said, "the future doesn't belong to fear, it belongs to freedom", a quote that later appeared in a Kerry/Edwards television advertisement.
Is there an answer to this question: What other two candidates did Tom Vilsack have on his list for possible running mates?

Answer: unanswerable

Problem: Exhibition game:

The Major League Baseball's preseason is also known as spring training. All MLB teams maintain a spring-training base in Arizona or Florida. The teams in Arizona make up the Cactus League, while the teams in Florida play in the Grapefruit League. Each team plays about 30 preseason games against other MLB teams. They may also play exhibitions against a local college team or a minor-league team from their farm system. Some days feature the team playing two games with two different rosters evenly divided up, which are known as "split-squad" games.
