Since the launch of the "Reinvent the Toilet Challenge", more than a dozen research teams, mainly at universities in the U.S., Europe, India, China and South Africa, have received grants to develop innovative on-site and off-site waste treatment solutions for the urban poor. The grants were in the order of 400,000 USD for their first phase, followed by typically 1-3 million USD for their second phase; many of them investigated resource recovery or processing technologies for excreta or fecal sludge.
What did many investigate

Problem: Please answer a question about the following article about Seattle:
Like most parts of the United States, government and laws are also run by a series of ballot initiatives (allowing citizens to pass or reject laws), referenda (allowing citizens to approve or reject legislation already passed), and propositions (allowing specific government agencies to propose new laws/tax increases directly to the people). Federally, Seattle is part of Washington's 7th congressional district, represented by Democrat Jim McDermott, elected in 1988 and one of Congress's liberal members. Ed Murray is currently serving as mayor.

Question: Read this and answer the question

The Norfolk Island Group Nepean Island is also home to breeding seabirds. The providence petrel was hunted to local extinction by the beginning of the 19th century, but has shown signs of returning to breed on Phillip Island. Other seabirds breeding there include the white-necked petrel, Kermadec petrel, wedge-tailed shearwater, Australasian gannet, red-tailed tropicbird and grey ternlet. The sooty tern (known locally as the whale bird) has traditionally been subject to seasonal egg harvesting by Norfolk Islanders.

Where has the providence petrel been seen breeding on Norfolk Island?
Answer: Phillip Island


Problem: Throughout the history of the South Slavs, the vernacular, literary, and written languages (e.g. Chakavian, Kajkavian, Shtokavian) of the various regions and ethnicities developed and diverged independently. Prior to the 19th century, they were collectively called "Illyric", "Slavic", "Slavonian", "Bosnian", "Dalmatian", "Serbian" or "Croatian". As such, the term Serbo-Croatian was first used by Jacob Grimm in 1824, popularized by the Vienna philologist Jernej Kopitar in the following decades, and accepted by Croatian Zagreb grammarians in 1854 and 1859. At that time, Serb and Croat lands were still part of the Ottoman and Austrian Empires. Officially, the language was called variously Serbo-Croat, Croato-Serbian, Serbian and Croatian, Croatian and Serbian, Serbian or Croatian, Croatian or Serbian. Unofficially, Serbs and Croats typically called the language "Serbian" or "Croatian", respectively, without implying a distinction between the two, and again in independent Bosnia and Herzegovina, "Bosnian", "Croatian", and "Serbian" were considered to be three names of a single official language. Croatian linguist Dalibor Brozović advocated the term Serbo-Croatian as late as 1988, claiming that in an analogy with Indo-European, Serbo-Croatian does not only name the two components of the same language, but simply charts the limits of the region in which it is spoken and includes everything between the limits (‘Bosnian’ and ‘Montenegrin’). Today, use of the term "Serbo-Croatian" is controversial due to the prejudice that nation and language must match. It is still used for lack of a succinct alternative, though alternative names have been used, such as Bosnian/Croatian/Serbian (BCS), which is often seen in political contexts such as the Hague War Crimes tribunal.
Who first used the term Serbo-Croatian in 1824?
The answer is the following: Jacob Grimm


Input: Article: There are two main termini for bus services. As the biggest operator, First uses stops around Pound Tree Road. This leaves the other terminal of West Quay available for other operators. Uni-link passes West Quay in both directions, and Wilts & Dorset drop passengers off and pick them up there, terminating at a series of bus stands along the road. Certain Bluestar services also do this, while others stop at Bargate and some loop round West Quay, stopping at Hanover Buildings. There was a tram system from 1879 to 1949.

Now answer this question: When did the tram system stop operating in Southampton?

Output:
1949
