Problem: American Idol:

The show pushed Fox to become the number one U.S. TV network amongst adults 1849, the key demographic coveted by advertisers, for an unprecedented eight consecutive years by 2012. Its success also helped lift the ratings of other shows that were scheduled around it such as House and Bones, and Idol, for years, had become Fox's strongest platform primetime television program for promoting eventual hit shows of the 2010s (of the same network) such as Glee and New Girl. The show, its creator Simon Fuller claimed, "saved Fox".

What television network originally aired the show Glee?

A: Fox

Problem: A route through Beringia is seen as more likely than the Solutrean hypothesis. Kashani et al. 2012 state that "The similarities in ages and geographical distributions for C4c and the previously analyzed X2a lineage provide support to the scenario of a dual origin for Paleo-Indians. Taking into account that C4c is deeply rooted in the Asian portion of the mtDNA phylogeny and is indubitably of Asian origin, the finding that C4c and X2a are characterized by parallel genetic histories definitively dismisses the controversial hypothesis of an Atlantic glacial entry route into North America."
Because C4c and X2a are characterized by parallel genetic histories means what controversial hypothesis may be dismissed?
---
Answer: an Atlantic glacial entry route into North America

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Buddhism began to spread throughout Japan during the Heian period, primarily through two major esoteric sects, Tendai and Shingon. Tendai originated in China and is based on the Lotus Sutra, one of the most important sutras of Mahayana Buddhism; Saicho was key to its transmission to Japan. Shingon is the Japanese transmission of the Chinese Chen Yen school. Shingon, brought to Japan by the monk Kukai, emphasizes Esoteric Buddhism. Both Kukai and Saicho aimed to connect state and religion and establish support from the aristocracy, leading to the notion of 'aristocratic Buddhism'. An important element of Tendai doctrine was the suggestion that enlightenment was accessible to "every creature". Saicho also sought independent ordination for Tendai monks. A close relationship developed between the Tendai monastery complex on Mount Hiei and the imperial court in its new capital at the foot of the mountain. As a result, Tendai emphasized great reverence for the emperor and the nation. Kammu himself was a notable patron of the otherworldly Tendai sect, which rose to great power over the ensuing centuries. Kukai greatly impressed the emperors who succeeded Emperor Kammu, and also generations of Japanese, not only with his holiness but also with his poetry, calligraphy, painting, and sculpture. Shingon, through its use of "rich symbols, rituals and mandalas" held a wide-ranging appeal.
Where did Kukai bring Tendai Buddhism to?
A: unanswerable

Context and question: In conjunction with the system of months there is a system of weeks. A physical or electronic calendar provides conversion from a given date to the weekday, and shows multiple dates for a given weekday and month. Calculating the day of the week is not very simple, because of the irregularities in the Gregorian system. When the Gregorian calendar was adopted by each country, the weekly cycle continued uninterrupted. For example, in the case of the few countries that adopted the reformed calendar on the date proposed by Gregory XIII for the calendar's adoption, Friday, 15 October 1582, the preceding date was Thursday, 4 October 1582 (Julian calendar).
Why is calculating the days of the Gregorian calendar not simple?
Answer: irregularities

Question: For many centuries, wealthy and powerful members of the szlachta sought to gain legal privileges over their peers. Few szlachta were wealthy enough to be known as magnates (karmazynithe "Crimsons", from the crimson colour of their boots). A proper magnate should be able to trace noble ancestors back for many generations and own at least 20 villages or estates. He should also hold a major office in the Commonwealth.
Is there an answer to this question: Who is properly in the major office in the commonwealth?

Answer: magnates

Question: Delicate sounds and fine overtones were mostly lost, because it took a lot of sound energy to vibrate the recording horn diaphragm and cutting mechanism. There were acoustic limitations due to mechanical resonances in both the recording and playback system. Some pictures of acoustic recording sessions show horns wrapped with tape to help mute these resonances. Even an acoustic recording played back electrically on modern equipment sounds like it was recorded through a horn, notwithstanding a reduction in distortion because of the modern playback. Toward the end of the acoustic era, there were many fine examples of recordings made with horns.
Is there an answer to this question: What were issues facing play back and recording mechanics?

Answer:
acoustic limitations
