The national media ran with the story, including a photo in USA Today. The game was played between the two teams in Sacramento's Arco Arena, as part of the AFL's 'Barnstorming America' tour. Foster had walked onto the field of play to mediate an altercation between the two teams when Haering, a former NFL assistant, punched him in the jaw. Haering was suspended without pay.

Input: Read this: For reasons that remain obscure, the planet's thermosphere is at an anomalously high temperature of about 750 K. The planet is too far from the Sun for this heat to be generated by ultraviolet radiation. One candidate for a heating mechanism is atmospheric interaction with ions in the planet's magnetic field. Other candidates are gravity waves from the interior that dissipate in the atmosphere. The thermosphere contains traces of carbon dioxide and water, which may have been deposited from external sources such as meteorites and dust.
Question: Where would gravity waves in Neptune's interior appear?

Output: unanswerable

Input: Read this: Devotions to artistic depictions of Mary vary among Christian traditions. There is a long tradition of Roman Catholic Marian art and no image permeates Catholic art as does the image of Madonna and Child. The icon of the Virgin Theotokos with Christ is without doubt the most venerated icon in the Orthodox Church. Both Roman Catholic and Orthodox Christians venerate images and icons of Mary, given that the Second Council of Nicaea in 787 permitted their veneration with the understanding that those who venerate the image are venerating the reality of the person it represents, and the 842 Synod of Constantinople confirming the same. According to Orthodox piety and traditional practice, however, believers ought to pray before and venerate only flat, two-dimensional icons, and not three-dimensional statues.
Question: In what year was the first image of the Madonna and Child found?

Output:
unanswerable
