Problem: Time:

Time has historically been closely related with space, the two together merging into spacetime in Einstein's special relativity and general relativity. According to these theories, the concept of time depends on the spatial reference frame of the observer, and the human perception as well as the measurement by instruments such as clocks are different for observers in relative motion. For example, if a spaceship carrying a clock flies through space at (very nearly) the speed of light, its crew does not notice a change in the speed of time on board their vessel because everything traveling at the same speed slows down at the same rate (including the clock, the crew's thought processes, and the functions of their bodies). However, to a stationary observer watching the spaceship fly by, the spaceship appears flattened in the direction it is traveling and the clock on board the spaceship appears to move very slowly.

A crew in a spaceship travelling nearly the speed of light will not notice the change in what?
---
A: in the speed of time on board their vessel

Problem: The lower regions and larger towns of the Alps are well-served by motorways and main roads, but higher mountain passes and byroads, which are amongst the highest in Europe, can be treacherous even in summer due to steep slopes. Many passes are closed in winter. A multitude of airports around the Alps (and some within), as well as long-distance rail links from all neighbouring countries, afford large numbers of travellers easy access from abroad.
When are many passes in the Alps closed?
---
Answer: winter

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the nearby parish of Stoke Damerel the first dockyard, HMNB Devonport, opened in 1690 on the eastern bank of the River Tamar. Further docks were built here in 1727, 1762 and 1793. The settlement that developed here was called "Dock" or "Plymouth Dock" at the time, and a new town, separate from Plymouth, grew up. In 1712 there were 318 men employed and by 1733 it had grown to a population of 3,000 people.
In what year was HMNB Davenport established?
A: 1690

Context and question: The official English name of the system is BeiDou Navigation Satellite System. It is named after the Big Dipper constellation, which is known in Chinese as Beidou. The name literally means "Northern Dipper", the name given by ancient Chinese astronomers to the seven brightest stars of the Ursa Major constellation. Historically, this set of stars was used in navigation to locate the North Star Polaris. As such, the name BeiDou also serves as a metaphor for the purpose of the satellite navigation system.
What was the Little Dipper constellation used for?
Answer: unanswerable

Question: The MC controls the conferencing while it is active on the signaling plane, which is simply where the system manages conferencing creation, endpoint signaling and in-conferencing controls. This component negotiates parameters with every endpoint in the network and controls conferencing resources. While the MC controls resources and signaling negotiations, the MP operates on the media plane and receives media from each endpoint. The MP generates output streams from each endpoint and redirects the information to other endpoints in the conference.
Is there an answer to this question: What signaling negotiations does the MP operate on?

Answer: unanswerable

Question: Ziggurats (Sumerian temples) each had an individual name and consisted of a forecourt, with a central pond for purification. The temple itself had a central nave with aisles along either side. Flanking the aisles would be rooms for the priests. At one end would stand the podium and a mudbrick table for animal and vegetable sacrifices. Granaries and storehouses were usually located near the temples. After a time the Sumerians began to place the temples on top of multi-layered square constructions built as a series of rising terraces, giving rise to the Ziggurat style.
Is there an answer to this question: what was a precursor to pyramids?

Answer:
unanswerable
