Input: Read this: The surface bedrock under the Miami area is called Miami oolite or Miami limestone. This bedrock is covered by a thin layer of soil, and is no more than 50 feet (15 m) thick. Miami limestone formed as the result of the drastic changes in sea level associated with recent glaciations or ice ages. Beginning some 130,000 years ago the Sangamonian Stage raised sea levels to approximately 25 feet (8 m) above the current level. All of southern Florida was covered by a shallow sea. Several parallel lines of reef formed along the edge of the submerged Florida plateau, stretching from the present Miami area to what is now the Dry Tortugas. The area behind this reef line was in effect a large lagoon, and the Miami limestone formed throughout the area from the deposition of oolites and the shells of bryozoans. Starting about 100,000 years ago the Wisconsin glaciation began lowering sea levels, exposing the floor of the lagoon. By 15,000 years ago, the sea level had dropped to 300 to 350 feet (90 to 110 m) below the contemporary level. The sea level rose quickly after that, stabilizing at the current level about 4000 years ago, leaving the mainland of South Florida just above sea level.
Question: What isn't another name for Miami limestone?

QUES: In the 1990s, Dell switched from using primarily ATX motherboards and PSU to using boards and power supplies with mechanically identical but differently wired connectors. This meant customers wishing to upgrade their hardware would have to replace parts with scarce Dell-compatible parts instead of commonly available parts. While motherboard power connections reverted to the industry standard in 2003, Dell continues to remain secretive about their motherboard pin-outs for peripherals (such as MMC readers and power on/off switches and LEDs).

With what kind of parts weren't consumers able to upgrade their Dell systems with?
What is the answer?

QUES: Among all cities in the Mediterranean part of the European Union, Limassol has one of the warmest winters, in the period January – February average temperature is 17–18 °C (63–64 °F) during the day and 7–8 °C (45–46 °F) at night, in other coastal locations in Cyprus is generally 16–17 °C (61–63 °F) during the day and 6–8 °C (43–46 °F) at night. During March, Limassol has average temperatures of 19–20 °C (66–68 °F) during the day and 9–11 °C (48–52 °F) at night, in other coastal locations in Cyprus is generally 17–19 °C (63–66 °F) during the day and 8–10 °C (46–50 °F) at night.
Which cities has one of the warmest winters in the European Union?

ANS: Limassol


The terms piracy and theft are often associated with copyright infringement. The original meaning of piracy is "robbery or illegal violence at sea", but the term has been in use for centuries as a synonym for acts of copyright infringement. Theft, meanwhile, emphasizes the potential commercial harm of infringement to copyright holders. However, copyright is a type of intellectual property, an area of law distinct from that which covers robbery or theft, offenses related only to tangible property. Not all copyright infringement results in commercial loss, and the U.S. Supreme Court ruled in 1985 that infringement does not easily equate with theft.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What kind of property is copyright not used for?
Ah, so.. unanswerable


Question: Nanjing is the transportation hub in eastern China and the downstream Yangtze River area. Different means of transportation constitute a three-dimensional transport system that includes land, water and air. As in most other Chinese cities, public transportation is the dominant mode of travel of the majority of the citizens. As of October 2014, Nanjing had five bridges and two tunnels over the Yangtze River, which are tying districts north of the river with the city centre on the south bank.
Try to answer this question if possible: What are the three types of transport in Nanjing?
Answer: land, water and air


Context and question: One example of omnidirectional antennas is the very common vertical antenna or whip antenna consisting of a metal rod (often, but not always, a quarter of a wavelength long). A dipole antenna is similar but consists of two such conductors extending in opposite directions, with a total length that is often, but not always, a half of a wavelength long. Dipoles are typically oriented horizontally in which case they are weakly directional: signals are reasonably well radiated toward or received from all directions with the exception of the direction along the conductor itself; this region is called the antenna blind cone or null.
What type of antenna would most likely be a half a wavelength long?
Answer:
dipole
