Input: Read this: Estonia lies on the eastern shores of the Baltic Sea immediately across the Gulf of Finland from Finland on the level northwestern part of the rising East European platform between 57.3 and 59.5 N and 21.5 and 28.1 E. Average elevation reaches only 50 metres (164 ft) and the country's highest point is the Suur Munamagi in the southeast at 318 metres (1,043 ft). There is 3,794 kilometres (2,357 mi) of coastline marked by numerous bays, straits, and inlets. The number of islands and islets is estimated at some 2,355 (including those in lakes). Two of them are large enough to constitute separate counties: Saaremaa and Hiiumaa. A small, recent cluster of meteorite craters, the largest of which is called Kaali is found on Saaremaa, Estonia.
Question: What is the average elevation of Estonia?

Output: 50 metres (164 ft)

QUES: Despite their close genetic relationship and the ability to inter-breed, there are a number of diagnostic features to distinguish the gray wolves from domestic dogs. Domesticated dogs are clearly distinguishable from wolves by starch gel electrophoresis of red blood cell acid phosphatase. The tympanic bullae are large, convex and almost spherical in gray wolves, while the bullae of dogs are smaller, compressed and slightly crumpled. Compared to equally sized wolves, dogs tend to have 20% smaller skulls and 30% smaller brains.:35 The teeth of gray wolves are also proportionately larger than those of dogs; the premolars and molars of wolves are much less crowded and have more complex cusp patterns. Wolves do not have dewclaws on their back legs, unless there has been admixture with dogs. Dogs lack a functioning pre-caudal gland, and most enter estrus twice yearly, unlike gray wolves which only do so once a year. Dogs require fewer calories to function than wolves. The dog's limp ears may be the result of atrophy of the jaw muscles. The skin of domestic dogs tends to be thicker than that of wolves, with some Inuit tribes favoring the former for use as clothing due to its greater resistance to wear and tear in harsh weather.
Which typically has thicker skin, dogs or wolves?

ANS: dogs.

Railroads have been an important method of transportation in Montana since the 1880s. Historically, the state was traversed by the main lines of three east-west transcontinental routes: the Milwaukee Road, the Great Northern, and the Northern Pacific. Today, the BNSF Railway is the state's largest railroad, its main transcontinental route incorporating the former Great Northern main line across the state. Montana RailLink, a privately held Class II railroad, operates former Northern Pacific trackage in western Montana.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How long have railroads been important since in Montana
Ah, so.. 1880s

Question: USB is a serial bus, using four shielded wires for the USB 2.0 variant: two for power (VBUS and GND), and two for differential data signals (labelled as D+ and D in pinouts). Non-Return-to-Zero Inverted (NRZI) encoding scheme is used for transferring data, with a sync field to synchronize the host and receiver clocks. D+ and D signals are transmitted on a twisted pair, providing half-duplex data transfers for USB 2.0. Mini and micro connectors have their GND connections moved from pin #4 to pin #5, while their pin #4 serves as an ID pin for the On-The-Go host/client identification.
Try to answer this question if possible: What is USB?
Answer: a serial bus

Question: Higher education, also called tertiary, third stage, or postsecondary education, is the non-compulsory educational level that follows the completion of a school such as a high school or secondary school. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges and universities mainly provide tertiary education. Collectively, these are sometimes known as tertiary institutions. Individuals who complete tertiary education generally receive certificates, diplomas, or academic degrees.
