Iranian scientists outside Iran have also made some major contributions to science. In 1960, Ali Javan co-invented the first gas laser, and fuzzy set theory was introduced by Lotfi Zadeh. Iranian cardiologist, Tofy Mussivand invented and developed the first artificial cardiac pump, the precursor of the artificial heart. Furthering research and treatment of diabetes, HbA1c was discovered by Samuel Rahbar. Iranian physics is especially strong in string theory, with many papers being published in Iran. Iranian-American string theorist Kamran Vafa proposed the Vafa-Witten theorem together with Edward Witten. In August 2014, Maryam Mirzakhani became the first-ever woman, as well as the first-ever Iranian, to receive the Fields Medal, the highest prize in mathematics.

When did Ali Javan, an Iranian scientist, co-invent the first gas laser?
Answer: 1960

Problem: Stemmatics, stemmology or stemmatology is a rigorous approach to textual criticism. Karl Lachmann (17931851) greatly contributed to making this method famous, even though he did not invent it. The method takes its name from the word stemma. The Ancient Greek word and its loanword in classical Latin stemmata may refer to "family trees". This specific meaning shows the relationships of the surviving witnesses (the first known example of such a stemma, albeit with the name, dates from 1827). The family tree is also referred to as a cladogram. The method works from the principle that "community of error implies community of origin." That is, if two witnesses have a number of errors in common, it may be presumed that they were derived from a common intermediate source, called a hyparchetype. Relations between the lost intermediates are determined by the same process, placing all extant manuscripts in a family tree or stemma codicum descended from a single archetype. The process of constructing the stemma is called recension, or the Latin recensio.
What is recension?
The answer is the following: The process of constructing the stemma

Montana schoolchildren played a significant role in selecting several state symbols. The state tree, the ponderosa pine, was selected by Montana schoolchildren as the preferred state tree by an overwhelming majority in a referendum held in 1908. However, the legislature did not designate a state tree until 1949, when the Montana Federation of Garden Clubs, with the support of the state forester, lobbied for formal recognition. Schoolchildren also chose the western meadowlark as the state bird, in a 1930 vote, and the legislature acted to endorse this decision in 1931. Similarly, the secretary of state sponsored a children's vote in 1981 to choose a state animal, and after 74 animals were nominated, the grizzly bear won over the elk by a 21 margin. The students of Livingston started a statewide school petition drive plus lobbied the governor and the state legislature to name the Maiasaura as the state fossil in 1985.
What is the state animal of Montana?
grizzly bear

Input: Samoa
The Samoan islands have been produced by vulcanism, the source of which is the Samoa hotspot which is probably the result of a mantle plume. While all of the islands have volcanic origins, only Savai'i, the western most island in Samoa, is volcanically active with the most recent eruptions in Mt Matavanu (19051911), Mata o le Afi (1902) and Mauga Afi (1725). The highest point in Samoa is Mt Silisili, at 1858 m (6,096 ft). The Saleaula lava fields situated on the central north coast of Savai'i are the result of the Mt Matavanu eruptions which left 50 km (20 sq mi) of solidified lava.

How many meters is 6,096 feet?
Output: 1858

Input: Article: CAMRA have surveyed the 50,000 pubs in Britain and they believe that there are very few pubs that still have classic snugs. These are on a historic interiors list in order that they can be preserved.

Now answer this question: According to CAMRA, how many pubs in Britain possess classic snugs?

Output: very few

Problem: United States President Barack Obama and key advisers introduced a series of regulatory proposals in June 2009. The proposals address consumer protection, executive pay, bank financial cushions or capital requirements, expanded regulation of the shadow banking system and derivatives, and enhanced authority for the Federal Reserve to safely wind-down systemically important institutions, among others. In January 2010, Obama proposed additional regulations limiting the ability of banks to engage in proprietary trading. The proposals were dubbed "The Volcker Rule", in recognition of Paul Volcker, who has publicly argued for the proposed changes.
What was introduced by President Barack Obama in June 2009?
The answer is the following:
a series of regulatory proposals
