Problem: Please answer a question about the following article about Melbourne:
Between 1836 and 1842 Victorian Aboriginal groups were largely dispossessed[by whom?] of their land. By January 1844, there were said to be 675 Aborigines resident in squalid camps in Melbourne. The British Colonial Office appointed five Aboriginal Protectors for the Aborigines of Victoria, in 1839, however their work was nullified by a land policy that favoured squatters to take possession of Aboriginal lands. By 1845, fewer than 240 wealthy Europeans held all the pastoral licences then issued in Victoria and became a powerful political and economic force in Victoria for generations to come.
Who were the people that were power political and economic force in Victoria in 1845?
A: 240 wealthy Europeans

The university is affiliated with the Congregation of Holy Cross (Latin: Congregatio a Sancta Cruce, abbreviated postnominals: "CSC"). While religious affiliation is not a criterion for admission, more than 93% of students identify as Christian, with over 80% of the total being Catholic. Collectively, Catholic Mass is celebrated over 100 times per week on campus, and a large campus ministry program provides for the faith needs of the community. There are multitudes of religious statues and artwork around campus, most prominent of which are the statue of Mary on the Main Building, the Notre Dame Grotto, and the Word of Life mural on Hesburgh Library depicting Christ as a teacher. Additionally, every classroom displays a crucifix. There are many religious clubs (catholic and non-Catholic) at the school, including Council #1477 of the Knights of Columbus (KOC), Baptist Collegiate Ministry (BCM), Jewish Club, Muslim Student Association, Orthodox Christian Fellowship, The Mormon Club, and many more. The Notre Dame KofC are known for being the first collegiate council of KofC, operating a charitable concession stand during every home football game and owning their own building on campus which can be used as a cigar lounge. Fifty-seven chapels are located throughout the campus.

How many chapels are on the Notre Dame campus?
Answer: Fifty-seven

Problem: The Age of Enlightenment is a time in Western philosophy and cultural life centered upon the 18th century in which reason was advocated as the primary source and legitimacy for authority. Enlightenment gained momentum more or less simultaneously in many parts of Europe and America. Developing during the Enlightenment era, Renaissance humanism as an intellectual movement spread across Europe. The basic training of the humanist was to speak well and write (typically, in the form of a letter). The term umanista comes from the latter part of the 15th century. The people were associated with the studia humanitatis, a novel curriculum that was competing with the quadrivium and scholastic logic.
What is the basic training of a humanist?
The answer is the following: speak well and write

The Appalachian Mountains are the coolest area of the state, with temperatures averaging in the low 40s and upper 30s F (63 C) for highs in the winter and falling into the low 20s F (5 C) or lower on winter nights. Relatively cool summers have temperatures rarely rising above 80 F (27 C). Average snowfall in many areas exceeds 30 in (76 cm) per year, and can be heavy at the higher elevations; for example, during the Blizzard of 1993 more than 60 in (152 cm) of snow fell on Mount Mitchell over a period of three days. Mount Mitchell has received snow in every month of the year.
Average snowfall in the Appalachians can exceed how many inches?
30

Input: Education
Informal learning is one of three forms of learning defined by the Organisation for Economic Co-operation and Development (OECD). Informal learning occurs in a variety of places, such as at home, work, and through daily interactions and shared relationships among members of society. For many learners this includes language acquisition, cultural norms and manners. Informal learning for young people is an ongoing process that also occurs in a variety of places, such as out of school time, in youth programs at community centers and media labs.

Where does informal learning occur?
Output: home, work, and through daily interactions

Problem: Please answer a question about the following article about Light-emitting diode:
The light from LEDs can be modulated very quickly so they are used extensively in optical fiber and free space optics communications. This includes remote controls, such as for TVs, VCRs, and LED Computers, where infrared LEDs are often used. Opto-isolators use an LED combined with a photodiode or phototransistor to provide a signal path with electrical isolation between two circuits. This is especially useful in medical equipment where the signals from a low-voltage sensor circuit (usually battery-powered) in contact with a living organism must be electrically isolated from any possible electrical failure in a recording or monitoring device operating at potentially dangerous voltages. An optoisolator also allows information to be transferred between circuits not sharing a common ground potential.
What does an optoisolator do?
A:
allows information to be transferred between circuits not sharing a common ground potential
