Problem: Richard Feynman:

Feynman devoted the latter half of his book What Do You Care What Other People Think? to his experience on the Rogers Commission, straying from his usual convention of brief, light-hearted anecdotes to deliver an extended and sober narrative. Feynman's account reveals a disconnect between NASA's engineers and executives that was far more striking than he expected. His interviews of NASA's high-ranking managers revealed startling misunderstandings of elementary concepts. For instance, NASA managers claimed that there was a 1 in 100,000 chance of a catastrophic failure aboard the shuttle, but Feynman discovered that NASA's own engineers estimated the chance of a catastrophe at closer to 1 in 200. He concluded that the space shuttle reliability estimate by NASA management was fantastically unrealistic, and he was particularly angered that NASA used these figures to recruit Christa McAuliffe into the Teacher-in-Space program. He warned in his appendix to the commission's report (which was included only after he threatened not to sign the report), "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled."

Problem: On the other hand, classical (analog) television transmissions are usually horizontally polarized, because in urban areas buildings can reflect the electromagnetic waves and create ghost images due to multipath propagation. Using horizontal polarization, ghosting is reduced because the amount of reflection of electromagnetic waves in the p polarization (horizontal polarization off the side of a building) is generally less than s (vertical, in this case) polarization. Vertically polarized analog television has nevertheless been used in some rural areas. In digital terrestrial television such reflections are less problematic, due to robustness of binary transmissions and error correction.
When is ghosting reduced?

Answer: horizontal polarization


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Congress acted defiantly toward the Supreme Court by passing the Drug Kingpin Act of 1988 and the Federal Death Penalty Act of 1994 that made roughly fifty crimes punishable by death, including crimes that do not always involve the death of someone. Such non-death capital offenses include treason, espionage (spying for another country), and high-level drug trafficking. Since no one has yet been sentenced to death for such non-death capital offenses, the Supreme Court has not ruled on their constitutionality.
What is another term for the act of spying for another country?
A: espionage


Context and question: Most historical accounts state that the island was discovered on 21 May 1502 by the Galician navigator João da Nova sailing at the service of Portugal, and that he named it "Santa Helena" after Helena of Constantinople. Another theory holds that the island found by da Nova was actually Tristan da Cunha, 2,430 kilometres (1,510 mi) to the south, and that Saint Helena was discovered by some of the ships attached to the squadron of Estêvão da Gama expedition on 30 July 1503 (as reported in the account of clerk Thomé Lopes). However, a paper published in 2015 reviewed the discovery date and dismissed the 18 August as too late for da Nova to make a discovery and then return to Lisbon by 11 September 1502, whether he sailed from St Helena or Tristan da Cunha. It demonstrates the 21 May is probably a Protestant rather than Catholic or Orthodox feast-day, first quoted in 1596 by Jan Huyghen van Linschoten, who was probably mistaken because the island was discovered several decades before the Reformation and start of Protestantism. The alternative discovery date of 3 May, the Catholic feast-day for the finding of the True Cross by Saint Helena in Jerusalem, quoted by Odoardo Duarte Lopes and Sir Thomas Herbert is suggested as being historically more credible.
What person is Saint Helena Island named after?
Answer: Helena of Constantinople


Question: The city's total area is 468.9 square miles (1,214 km2). 164.1 sq mi (425 km2) of this is water and 304.8 sq mi (789 km2) is land. The highest point in the city is Todt Hill on Staten Island, which, at 409.8 feet (124.9 m) above sea level, is the highest point on the Eastern Seaboard south of Maine. The summit of the ridge is mostly covered in woodlands as part of the Staten Island Greenbelt.
Is there an answer to this question: What is the total area of New York City in square miles?

Answer: 468.9


Question: There are several major annual events such as First Night, which occurs on New Year's Eve, the Boston Early Music Festival, the annual Boston Arts Festival at Christopher Columbus Waterfront Park, and Italian summer feasts in the North End honoring Catholic saints.

They include the week-long Harborfest festivities and a Boston Pops concert accompanied by fireworks on the banks of the Charles River.
Is there an answer to this question: How long are the Harbor-Fest festivities?

Answer:
week-long
