Input: Article: A commutator is a mechanism used to switch the input of most DC machines and certain AC machines consisting of slip ring segments insulated from each other and from the electric motor's shaft. The motor's armature current is supplied through the stationary brushes in contact with the revolving commutator, which causes required current reversal and applies power to the machine in an optimal manner as the rotor rotates from pole to pole. In absence of such current reversal, the motor would brake to a stop. In light of significant advances in the past few decades due to improved technologies in electronic controller, sensorless control, induction motor, and permanent magnet motor fields, electromechanically commutated motors are increasingly being displaced by externally commutated induction and permanent-magnet motors.

Now answer this question: From where is current to the motor supplied?

Output: stationary brushes


Article: In 1875, Bell developed an acoustic telegraph and drew up a patent application for it. Since he had agreed to share U.S. profits with his investors Gardiner Hubbard and Thomas Sanders, Bell requested that an associate in Ontario, George Brown, attempt to patent it in Britain, instructing his lawyers to apply for a patent in the U.S. only after they received word from Britain (Britain would issue patents only for discoveries not previously patented elsewhere).

Question: In what country other than the U.S. did Bell try to patent his telegraph?
Ans: Britain


Here is a question about this article: Probably the most influential single device on the interpretation of these characters was the Teletype Model 33 ASR, which was a printing terminal with an available paper tape reader/punch option. Paper tape was a very popular medium for long-term program storage until the 1980s, less costly and in some ways less fragile than magnetic tape. In particular, the Teletype Model 33 machine assignments for codes 17 (Control-Q, DC1, also known as XON), 19 (Control-S, DC3, also known as XOFF), and 127 (Delete) became de facto standards. The Model 33 was also notable for taking the description of Control-G (BEL, meaning audibly alert the operator) literally as the unit contained an actual bell which it rang when it received a BEL character. Because the keytop for the O key also showed a left-arrow symbol (from ASCII-1963, which had this character instead of underscore), a noncompliant use of code 15 (Control-O, Shift In) interpreted as "delete previous character" was also adopted by many early timesharing systems but eventually became neglected.
What is the answer to this question: What was the Teletype Model 33 ASR?
****
So... a printing terminal with an available paper tape reader/punch option


The problem: Answer a question about this article:
Some Western media have reported on Chinese accusations of Western media bias. The Daily Telegraph published an opinion piece by the Chinese ambassador to the United Kingdom, Fu Ying, who accused Western media of "demonising" China during their coverage of the torch relays. The Telegraph also asked its readers to send their views in response to the question "Is the West demonising China?" The BBC reported on a demonstration in Sydney by Chinese Australians "voicing support for Beijing amid controversy over Tibet" and protesting against what they saw as Western media bias. The report showed demonstrators carrying signs which read "Shame on some Western media", "BBC CNN lies too" and "Stop media distortion!". One demonstrator interviewed by the BBC stated: "I saw some news from CNN, from the BBC, some media [inaudible], and they are just lying." Libération also reported that it had been accused of bias by the Chinese media.
What French newspaper did the Chinese media accuse of bias?
****
The answer: Libération


Problem: Please answer a question about the following article about Myanmar:
Typical jungle animals, particularly tigers and leopards, occur sparsely in Myanmar. In upper Myanmar, there are rhinoceros, wild buffalo, wild boars, deer, antelope, and elephants, which are also tamed or bred in captivity for use as work animals, particularly in the lumber industry. Smaller mammals are also numerous, ranging from gibbons and monkeys to flying foxes and tapirs. The abundance of birds is notable with over 800 species, including parrots, peafowl, pheasants, crows, herons, and paddybirds. Among reptile species there are crocodiles, geckos, cobras, Burmese pythons, and turtles. Hundreds of species of freshwater fish are wide-ranging, plentiful and are very important food sources. For a list of protected areas, see List of protected areas of Myanmar.
What is an important protein source  in the Burmese diet?
A: Hundreds of species of freshwater fish


Question: Read this and answer the question

The Solar Hijri calendar, also called the Shamsi Hijri calendar, and abbreviated as SH, is the official calendar of Iran and Afghanistan. It begins on the vernal equinox. Each of the twelve months corresponds with a zodiac sign. The first six months have 31 days, the next five have 30 days, and the last month has 29 days in usual years but 30 days in leap years. The year of Prophet Muhammad's migration to Medina (622 CE) is fixed as the first year of the calendar, and the New Year's Day always falls on the March equinox.

What is one way to abbreviate the Solar Hiljri calender?
Answer:
SH
