question:
Passage: Despite yet another offer from the Institute for Advanced Study, Feynman rejected the Institute on the grounds that there were no teaching duties: Feynman felt that students were a source of inspiration and teaching was a diversion during uncreative spells. Because of this, the Institute for Advanced Study and Princeton University jointly offered him a package whereby he could teach at the university and also be at the institute.[citation needed] Feynman instead accepted an offer from the California Institute of Technology (Caltech)—and as he says in his book Surely You're Joking Mr. Feynman!—because a desire to live in a mild climate had firmly fixed itself in his mind while he was installing tire chains on his car in the middle of a snowstorm in Ithaca.
answer:
Why did Feynman decide to accept all offers from the Institute of Advanced Study?


question:
Passage: In many parts of the world football evokes great passions and plays an important role in the life of individual fans, local communities, and even nations. R. Kapuscinski says that Europeans who are polite, modest, or humble fall easily into rage when playing or watching football games. The Côte d'Ivoire national football team helped secure a truce to the nation's civil war in 2006 and it helped further reduce tensions between government and rebel forces in 2007 by playing a match in the rebel capital of Bouaké, an occasion that brought both armies together peacefully for the first time. By contrast, football is widely considered to have been the final proximate cause for the Football War in June 1969 between El Salvador and Honduras. The sport also exacerbated tensions at the beginning of the Yugoslav Wars of the 1990s, when a match between Dinamo Zagreb and Red Star Belgrade degenerated into rioting in May 1990.
answer:
Which team helped remove a truce during a civil war in 2006?


question:
Passage: Approximately 26,000 citizen soldiers, sailors, and airmen and women, trained to the level of and interchangeable with their Regular Force counterparts, and posted to CAF operations or duties on a casual or ongoing basis, make up the Primary Reserve. This group is represented, though not commanded, at NDHQ by the Chief of Reserves and Cadets, who is usually a major general or rear admiral, and is divided into four components that are each operationally and administratively responsible to its corresponding environmental command in the Regular Force – the Naval Reserve (NAVRES), Land Force Reserve (LFR), and Air Reserve (AIRRES) – in addition to one force that does not fall under an environmental command, the Health Services Reserve under the Canadian Forces Health Services Group.
answer:

Who won't command the reserves?
