Input: Read this: 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.
Question:  What does an optoisolator don't do?

Output: unanswerable


QUES: In February 2012, Capello resigned from his role as England manager, following a disagreement with the FA over their request to remove John Terry from team captaincy after accusations of racial abuse concerning the player. Following this, there was media speculation that Harry Redknapp would take the job. However, on 1 May 2012, Roy Hodgson was announced as the new manager, just six weeks before UEFA Euro 2012. England managed to finish top of their group, winning two and drawing one of their fixtures, but exited the Championships in the quarter-finals via a penalty shoot-out, this time to Italy.

In what year did Capello resign as England's football manager?
What is the answer?

QUES: Usually, the short-term goal of open market operations is to achieve a specific short-term interest rate target. In other instances, monetary policy might instead entail the targeting of a specific exchange rate relative to some foreign currency or else relative to gold. For example, in the case of the United States the Federal Reserve targets the federal funds rate, the rate at which member banks lend to one another overnight. The other primary means of conducting monetary policy include: (i) Discount window lending (as lender of last resort); (ii) Fractional deposit lending (changes in the reserve requirement); (iii) Moral suasion (cajoling certain market players to achieve specified outcomes); (iv) "Open mouth operations" (talking monetary policy with the market).
What is the cajoling of certain market players to achieve member bank rates also known as?

ANS: unanswerable


Educational psychology can in part be understood through its relationship with other disciplines. It is informed primarily by psychology, bearing a relationship to that discipline analogous to the relationship between medicine and biology. Educational psychology in turn informs a wide range of specialties within educational studies, including instructional design, educational technology, curriculum development, organizational learning, special education and classroom management. Educational psychology both draws from and contributes to cognitive science and the learning sciences. In universities, departments of educational psychology are usually housed within faculties of education, possibly accounting for the lack of representation of educational psychology content in introductory psychology textbooks (Lucas, Blazek, & Raley, 2006).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How does educational psychology go misunderstood?
Ah, so.. unanswerable


Question: The depression had devastating effects in virtually every country, rich or poor. International trade plunged by half to two-thirds, as did personal income, tax revenue, prices and profits. Cities all around the world were hit hard, especially those dependent on heavy industry. Construction was virtually halted in many countries. Farming and rural areas suffered as crop prices fell by roughly 60 percent. Facing plummeting demand with few alternate sources of jobs, areas dependent on primary sector industries suffered the most.
Try to answer this question if possible: Where did the depression cause negative effects?
Answer: virtually every country


Input: Read this: A commonly seen example is the double happiness symbol 囍, formed as a ligature of 喜喜 and referred to by its disyllabic name (simplified Chinese: 双喜; traditional Chinese: 雙喜; pinyin: shuāngxǐ). In handwriting, numbers are very frequently squeezed into one space or combined – common ligatures include 廿 niàn, "twenty", normally read as 二十 èrshí, 卅 sà, "thirty", normally read as 三十 sānshí, and 卌 xì "forty", normally read as 四十 "sìshí". In some cases counters are also merged into one character, such as 七十人 qīshí rén "seventy people". Another common abbreviation is 门 with a "T" written inside it, for 問題, 问题, wèntí ("question; problem"), where the "T" is from pinyin for the second syllable tí 题. Since polysyllabic characters are often non-standard, they are often excluded incharcter dictionaries.
Question: What characters are often non-standard?

Output:
polysyllabic
