Problem: United States presidential election, 2004:

The second presidential debate was held at Washington University in St. Louis, Missouri, on October 8, moderated by Charles Gibson of ABC. Conducted in a town meeting format, less formal than the first presidential debate, this debate saw Bush and Kerry taking questions on a variety of subjects from a local audience. Bush attempted to deflect criticism of what was described as his scowling demeanor during the first debate, joking at one point about one of Kerry's remarks, "That answer made me want to scowl."

When was Charles Gibson first hired at ABC?

What type of camera did the Baird image dissector use?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Following the Fourth Crusade and the fall of Constantinople to the "Latins" in 1204 mainland Greece was split between the Greek Despotate of Epirus (a Byzantine successor state) and Frankish rule (known as the Frankokratia), while some islands came under Venetian rule. The re-establishment of the Byzantine imperial capital in Constantinople in 1261 was accompanied by the empire's recovery of much of the Greek peninsula, although the Frankish Principality of Achaea in the Peloponnese and the rival Greek Despotate of Epirus in the north both remained important regional powers into the 14th century, while the islands remained largely under Genoese and Venetian control.
Greece was split into sections of different rulers in what year?
A: 1204

Question: During his period in Milan, Montini was known as a progressive member of the Catholic hierarchy. Montini went new ways in pastoral care, which he reformed. He used his authority to ensure that the liturgical reforms of Pius XII were carried out at the local level and employed innovative methods to reach the people of Milan: Huge posters announced that 1,000 voices would speak to them from 10 to 24 November 1957. More than 500 priests and many bishops, cardinals and lay persons delivered 7,000 sermons in the period not only in churches but in factories, meeting halls, houses, courtyards, schools, offices, military barracks, hospitals, hotels and other places, where people meet. His goal was the re-introduction of faith to a city without much religion. "If only we can say Our Father and know what this means, then we would understand the Christian faith."
Is there an answer to this question: What part of Catholic ministry did Montini seek to reform?

Answer: pastoral care

On 22 August, one day after the talks broke down with France and Britain, Moscow revealed that Ribbentrop would visit Stalin the next day. This happened while the Soviets were still negotiating with the British and French missions in Moscow. With the Western nations unwilling to accede to Soviet demands, Stalin instead entered a secret NaziSoviet pact. On 24 August a 10-year non-aggression pact was signed with provisions that included: consultation, arbitration if either party disagreed, neutrality if either went to war against a third power, no membership of a group "which is directly or indirectly aimed at the other".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Part of the secret agreement between the Germans and the Soviets excluded a neutral diplomatic approach when?
Ah, so..
unanswerable
