Problem: Nanjing:

Port of Nanjing is the largest inland port in China, with annual cargo tonnage reached 191,970,000 t in 2012. The port area is 98 kilometres (61 mi) in length and has 64 berths including 16 berths for ships with a tonnage of more than 10,000. Nanjing is also the biggest container port along the Yangtze River; in March 2004, the one million container-capacity base, Longtan Containers Port Area opened, further consolidating Nanjing as the leading port in the region. As of 2010, it operated six public ports and three industrial ports.

How many containers can Longtan Containers Port Area handle?
---
A: one million container-capacity

Problem: In the traditional domain noted in RFC 1591, .org is for "organizations that didn't fit anywhere else" in the naming system, which implies that it is the proper category for non-commercial organizations if they are not governmental, educational, or one of the other types with a specific TLD. It is not designated specifically for charitable organizations or any specific organizational or tax-law status, however; it encompasses anything that is not classifiable as another category. Currently, no restrictions are enforced on registration of .com or .org, so one can find organizations of all sorts in either of these domains, as well as other top-level domains including newer, more specific ones which may apply to particular sorts of organizations such as .museum for museums or .coop for cooperatives. Organizations might also register by the appropriate country code top-level domain for their country.
What new domain designation should a museum use?

Answer: .museum

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In September 1998, the Fraunhofer Institute sent a letter to several developers of MP3 software stating that a license was required to "distribute and/or sell decoders and/or encoders". The letter claimed that unlicensed products "infringe the patent rights of Fraunhofer and Thomson. To make, sell and/or distribute products using the [MPEG Layer-3] standard and thus our patents, you need to obtain a license under these patents from us."
What did the letter claim would be required to distribute and/or sell decoders and/or encoders?
A: a license

Question: By 1620, the fishermen of England's West Country controlled most of Newfoundland's east coast. In 1627, William Payne, called St. John's "the principal prime and chief lot in all the whole country". The population grew slowly in the 17th century and St. John's was the largest settlement in Newfoundland when English naval officers began to take censuses around 1675. The population would grow in the summers with the arrival of migratory fishermen. In 1680, fishing ships (mostly from South Devon) set up fishing rooms at St. John's, bringing hundreds of Irish men into the port to operate inshore fishing boats.
Is there an answer to this question: Who controlled most of Newfoundland's east coast by 1620?

Answer: fishermen

Question: The lowest pressure that can be attained in a system is also dependent on many things other than the nature of the pumps. Multiple pumps may be connected in series, called stages, to achieve higher vacuums. The choice of seals, chamber geometry, materials, and pump-down procedures will all have an impact. Collectively, these are called vacuum technique. And sometimes, the final pressure is not the only relevant characteristic. Pumping systems differ in oil contamination, vibration, preferential pumping of certain gases, pump-down speeds, intermittent duty cycle, reliability, or tolerance to high leakage rates.
Is there an answer to this question: How do leakage rates usually happen?

Answer:
unanswerable
