Problem: High-definition television:

It also includes the alternative 1440×1152 HDMAC scan format. (According to some reports, a mooted 750-line (720p) format (720 progressively scanned lines) was viewed by some at the ITU as an enhanced television format rather than a true HDTV format, and so was not included, although 1920×1080i and 1280×720p systems for a range of frame and field rates were defined by several US SMPTE standards.)

 What were 1920x1080i and 1280x720p not defined by?

A: unanswerable


Problem: Marshall Islands:

In 1999, a private company built a tuna loining plant with more than 400 employees, mostly women. But the plant closed in 2005 after a failed attempt to convert it to produce tuna steaks, a process that requires half as many employees. Operating costs exceeded revenue, and the plant's owners tried to partner with the government to prevent closure. But government officials personally interested in an economic stake in the plant refused to help. After the plant closed, it was taken over by the government, which had been the guarantor of a $2 million loan to the business.[citation needed]

In what year was a tuna loining plant constructed?
---
A: 1999


Problem: Party leaders of the United States House of Representatives:

In the judgment of political scientist Randall Ripley, since 1883 "the candidate for Speaker nominated by the minority party has clearly been the Minority Leader." However, this assertion is subject to dispute. On December 3, 1883, the House elected Democrat John G. Carlisle of Kentucky as Speaker. Republicans placed in nomination for the speakership J. Warren Keifer of Ohio, who was Speaker the previous Congress. Clearly, Keifer was not the Republicans' minority leader. He was a discredited leader in part because as Speaker he arbitrarily handed out "choice jobs to close relatives ... all at handsome salaries." Keifer received "the empty honor of the minority nomination. But with it came a sting -- for while this naturally involves the floor leadership, he was deserted by his [partisan] associates and his career as a national figure terminated ingloriously." Representative Thomas Reed, R-ME, who later became Speaker, assumed the de facto role of minority floor leader in Keifer's stead. "[A]lthough Keifer was the minority's candidate for Speaker, Reed became its acknowledged leader, and ever after, so long as he served in the House, remained the most conspicuous member of his party.

Who was Ripley deserted by?

A: unanswerable


Problem: Frédéric Chopin:

In 1817 the Saxon Palace was requisitioned by Warsaw's Russian governor for military use, and the Warsaw Lyceum was reestablished in the Kazimierz Palace (today the rectorate of Warsaw University). Fryderyk and his family moved to a building, which still survives, adjacent to the Kazimierz Palace. During this period, Fryderyk was sometimes invited to the Belweder Palace as playmate to the son of the ruler of Russian Poland, Grand Duke Constantine; he played the piano for the Duke and composed a march for him. Julian Ursyn Niemcewicz, in his dramatic eclogue, "Nasze Przebiegi" ("Our Discourses", 1818), attested to "little Chopin's" popularity.

As a child Chopin was invited to play with the son of whom?
---
A:
Grand Duke Constantine
