Problem: One of the first demonstrations of the ability for telecommunications to help sign language users communicate with each other occurred when AT&T's videophone (trademarked as the "Picturephone") was introduced to the public at the 1964 New York World's Fair two deaf users were able to communicate freely with each other between the fair and another city. Various universities and other organizations, including British Telecom's Martlesham facility, have also conducted extensive research on signing via videotelephony. The use of sign language via videotelephony was hampered for many years due to the difficulty of its use over slow analogue copper phone lines, coupled with the high cost of better quality ISDN (data) phone lines. Those factors largely disappeared with the introduction of more efficient video codecs and the advent of lower cost high-speed ISDN data and IP (Internet) services in the 1990s.
In what decade were more efficient ways of using sign language via video-telephony developed?
The answer is the following: 1990s

Situated on one of the world's largest natural harbors, New York City consists of five boroughs, each of which is a separate county of New York State. The five boroughs Brooklyn, Queens, Manhattan, the Bronx, and Staten Island were consolidated into a single city in 1898. With a census-estimated 2014 population of 8,491,079 distributed over a land area of just 305 square miles (790 km2), New York is the most densely populated major city in the United States. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. By 2014 census estimates, the New York City metropolitan region remains by a significant margin the most populous in the United States, as defined by both the Metropolitan Statistical Area (20.1 million residents) and the Combined Statistical Area (23.6 million residents). In 2013, the MSA produced a gross metropolitan product (GMP) of nearly US$1.39 trillion, while in 2012, the CSA generated a GMP of over US$1.55 trillion, both ranking first nationally by a wide margin and behind the GDP of only twelve and eleven countries, respectively.
How man boroughs does New York City contain?
five

In February 2015, YouTube announced the launch of a new app specifically for use by children visiting the site, called YouTube Kids. It allows parental controls and restrictions on who can upload content, and is available for both Android and iOS devices. Later on August 26, 2015, YouTube Gaming was launched, a platform for video gaming enthusiasts intended to compete with Twitch.tv. 2015 also saw the announcement of a premium YouTube service titled YouTube Red, which provides users with both ad-free content as well as the ability to download videos among other features.

what was the name of the new app youtube launched?
Output: YouTube Kids

Input: Article: In 1998, Democratic voters dominated areas of the state with a high percentage of racial minorities and transplanted white liberals from the northeastern United States, known colloquially as "snowbirds". South Florida and the Miami metropolitan area are dominated by both racial minorities and white liberals. Because of this, the area has consistently voted as one of the most Democratic areas of the state. The Daytona Beach area is similar demographically and the city of Orlando has a large Hispanic population, which has often favored Democrats. Republicans, made up mostly of white conservatives, have dominated throughout much of the rest of Florida, particularly in the more rural and suburban areas. This is characteristic of its voter base throughout the Deep South.

Now answer this question: What are snowbirds

Output: white liberals from the northeastern United States, known colloquially as "snowbirds

Article: The doctrine of the last day and eschatology (the final fate of the universe) may be reckoned as the second great doctrine of the Quran. It is estimated that approximately one-third of the Quran is eschatological, dealing with the afterlife in the next world and with the day of judgment at the end of time. There is a reference to the afterlife on most pages of the Quran and belief in the afterlife is often referred to in conjunction with belief in God as in the common expression: "Believe in God and the last day". A number of suras such as 44, 56, 75, 78, 81 and 101 are directly related to the afterlife and its preparations. Some suras indicate the closeness of the event and warn people to be prepared for the imminent day. For instance, the first verses of Sura 22, which deal with the mighty earthquake and the situations of people on that day, represent this style of divine address: "O People! Be respectful to your Lord. The earthquake of the Hour is a mighty thing."

Question: Which natural disaster features in Sura 22?
Ans: earthquake

Input: Copper
Compounds that contain a carbon-copper bond are known as organocopper compounds. They are very reactive towards oxygen to form copper(I) oxide and have many uses in chemistry. They are synthesized by treating copper(I) compounds with Grignard reagents, terminal alkynes or organolithium reagents; in particular, the last reaction described produces a Gilman reagent. These can undergo substitution with alkyl halides to form coupling products; as such, they are important in the field of organic synthesis. Copper(I) acetylide is highly shock-sensitive but is an intermediate in reactions such as the Cadiot-Chodkiewicz coupling and the Sonogashira coupling. Conjugate addition to enones and carbocupration of alkynes can also be achieved with organocopper compounds. Copper(I) forms a variety of weak complexes with alkenes and carbon monoxide, especially in the presence of amine ligands.

What is produced when copper compounds are treated with organolithium reagents?
Output:
Gilman reagent
