Problem: Please answer a question about the following article about Bern:
The etymology of the name Bern is uncertain. According to the local legend, based on folk etymology, Berchtold V, Duke of Zahringen, the founder of the city of Bern, vowed to name the city after the first animal he met on the hunt, and this turned out to be a bear. It has long been considered likely that the city was named after the Italian city of Verona, which at the time was known as Bern in Middle High German. As a result of the find of the Bern zinc tablet in the 1980s, it is now more common to assume that the city was named after a pre-existing toponym of Celtic origin, possibly *berna "cleft". The bear was the heraldic animal of the seal and coat of arms of Bern from at least the 1220s. The earliest reference to the keeping of live bears in the Barengraben dates to the 1440s.
What is the earliest that they kept live bears in the Barengraben?
A: 1440s.
Problem: Please answer a question about the following article about Solar energy:
Agriculture and horticulture seek to optimize the capture of solar energy in order to optimize the productivity of plants. Techniques such as timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties can improve crop yields. While sunlight is generally considered a plentiful resource, the exceptions highlight the importance of solar energy to agriculture. During the short growing seasons of the Little Ice Age, French and English farmers employed fruit walls to maximize the collection of solar energy. These walls acted as thermal masses and accelerated ripening by keeping plants warm. Early fruit walls were built perpendicular to the ground and facing south, but over time, sloping walls were developed to make better use of sunlight. In 1699, Nicolas Fatio de Duillier even suggested using a tracking mechanism which could pivot to follow the Sun. Applications of solar energy in agriculture aside from growing crops include pumping water, drying crops, brooding chicks and drying chicken manure. More recently the technology has been embraced by vinters, who use the energy generated by solar panels to power grape presses.
During the Little Ice Age, what did English and French farmers use to increase collection of solar energy?
A: fruit walls
Problem: Please answer a question about the following article about Time:
Two distinct viewpoints on time divide many prominent philosophers. One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence. Sir Isaac Newton subscribed to this realist view, and hence it is sometimes referred to as Newtonian time. An opposing view is that time does not refer to any kind of actually existing dimension that events and objects "move through", nor to any entity that "flows", but that it is instead an intellectual concept (together with space and number) that enables humans to sequence and compare events. This second view, in the tradition of Gottfried Leibniz and Immanuel Kant, holds that space and time "do not exist in and of themselves, but ... are the product of the way we represent things", because we can know objects only as they appear to us.
How many main viewpoints divide many philosophers?
A: Two
Problem: Please answer a question about the following article about Orthodox Judaism:
According to the New Jersey Press Association, several media entities refrain from using the term "ultra-Orthodox", including the Religion Newswriters Association; JTA, the global Jewish news service; and the Star-Ledger, New Jersey's largest daily newspaper. The Star-Ledger was the first mainstream newspaper to drop the term. Several local Jewish papers, including New York's Jewish Week and Philadelphia's Jewish Exponent have also dropped use of the term. According to Rabbi Shammai Engelmayer, spiritual leader of Temple Israel Community Center in Cliffside Park and former executive editor of Jewish Week, this leaves "Orthodox" as "an umbrella term that designates a very widely disparate group of people very loosely tied together by some core beliefs."
What term do media entities refrain from using?
A:
"ultra-Orthodox
