Problem: This process begins when the user inputs a Uniform Resource Locator (URL), for example http://en.wikipedia.org/, into the browser. The prefix of the URL, the Uniform Resource Identifier or URI, determines how the URL will be interpreted. The most commonly used kind of URI starts with http: and identifies a resource to be retrieved over the Hypertext Transfer Protocol (HTTP). Many browsers also support a variety of other prefixes, such as https: for HTTPS, ftp: for the File Transfer Protocol, and file: for local files. Prefixes that the web browser cannot directly handle are often handed off to another application entirely. For example, mailto: URIs are usually passed to the user's default e-mail application, and news: URIs are passed to the user's default newsgroup reader.
What happens to newsgroup readers the web browser can't handle directly?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Dog behavior is the internally coordinated responses (actions or inactions) of the domestic dog (individuals or groups) to internal and/or external stimuli. As the oldest domesticated species, with estimates ranging from 9,00030,000 years BCE, the minds of dogs inevitably have been shaped by millennia of contact with humans. As a result of this physical and social evolution, dogs, more than any other species, have acquired the ability to understand and communicate with humans and they are uniquely attuned to our behaviors. Behavioral scientists have uncovered a surprising set of social-cognitive abilities in the otherwise humble domestic dog. These abilities are not possessed by the dog's closest canine relatives nor by other highly intelligent mammals such as great apes. Rather, these skills parallel some of the social-cognitive skills of human children.
Dogs have some social skills that parallel what?
A: human children

Context and question: The Gospel of Matthew describes many women at the crucifixion, some of whom are named in the Gospels. Apart from these women, the three Synoptic Gospels speak of the presence of others: "the chief priests, with the scribes and elders"; two robbers crucified, one on Jesus' right and one on his left, whom the Gospel of Luke presents as the penitent thief and the impenitent thief; "the soldiers", "the centurion and those who were with him, keeping watch over Jesus"; passers-by; "bystanders", "the crowds that had assembled for this spectacle"; and "his acquaintances"
How many acquaintances are named in the Gospels?
Answer: unanswerable

Question: Summers are typically warm and humid with a July daily average of 75.6 F (24.2 C). During this time, the city gets a sea breeze off the ocean that often makes daytime temperatures much cooler than inland areas, making Atlantic City a prime place for beating the summer heat from June through September. Average highs even just a few miles west of Atlantic City exceed 85 F (29 C) in July. Near the coast, temperatures reach or exceed 90 F (32 C) on an average of only 6.8 days a year, but this reaches 21 days at nearby Atlantic City Int'l.[a] Winters are cool, with January averaging 35.5 F (2 C). Spring and autumn are erratic, although they are usually mild with low humidity. The average window for freezing temperatures is November 20 to March 25, allowing a growing season of 239 days. Extreme temperatures range from 9 F (23 C) on February 9, 1934 to 104 F (40 C) on August 7, 1918.[b]
Is there an answer to this question: What is the extreme low temperature of Atlantic City?

Answer: 9 F

Question: Most cotton in the United States, Europe and Australia is harvested mechanically, either by a cotton picker, a machine that removes the cotton from the boll without damaging the cotton plant, or by a cotton stripper, which strips the entire boll off the plant. Cotton strippers are used in regions where it is too windy to grow picker varieties of cotton, and usually after application of a chemical defoliant or the natural defoliation that occurs after a freeze. Cotton is a perennial crop in the tropics, and without defoliation or freezing, the plant will continue to grow.
Is there an answer to this question: What weather conditions mandate the planting of stripper types of cotton?

Answer:
windy
