Input: Read this: Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign paddles) to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as Optical Landing System have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio.
Question: What are LSO's no longer being used to do?

Output: unanswerable

QUES: Family history is a risk factor for asthma, with many different genes being implicated. If one identical twin is affected, the probability of the other having the disease is approximately 25%. By the end of 2005, 25 genes had been associated with asthma in six or more separate populations, including GSTM1, IL10, CTLA-4, SPINK5, LTC4S, IL4R and ADAM33, among others. Many of these genes are related to the immune system or modulating inflammation. Even among this list of genes supported by highly replicated studies, results have not been consistent among all populations tested. In 2006 over 100 genes were associated with asthma in one genetic association study alone; more continue to be found.

What else are these genes closely related to?
What is the answer?
ANS: the immune system or modulating inflammation

QUES: The Dutch Republic, also known as the Republic of the Seven United Netherlands (Republiek der Zeven Verenigde Nederlanden), Republic of the United Netherlands or Republic of the Seven United Provinces (Republiek der Zeven Verenigde Provincien), was a republic in Europe existing from 1581, when part of the Netherlands separated from Spanish rule, until 1795. It preceded the Batavian Republic, the Kingdom of Holland, the United Kingdom of the Netherlands, and ultimately the modern Kingdom of the Netherlands. Alternative names include the United Provinces (Verenigde Provincien), Federated Dutch Provinces (Foederatae Belgii Provinciae), and Dutch Federation (Belgica Foederata).

Bell believed the photophone's principles were his life's "greatest achievement", telling a reporter shortly before his death that the photophone was "the greatest invention [I have] ever made, greater than the telephone". The photophone was a precursor to the fiber-optic communication systems which achieved popular worldwide usage in the 1980s. Its master patent was issued in December 1880, many decades before the photophone's principles came into popular use.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was fiber-optics first patented?
Ah, so.. 1880

Question: This is a socio-economic bloc of nations in or near the Caribbean Sea. Other outlying member states include the Co-operative Republic of Guyana and the Republic of Suriname in South America, along with Belize in Central America. The Turks and Caicos Islands, an associate member of CARICOM, and the Commonwealth of The Bahamas, a full member of CARICOM, are in the Atlantic, but near to the Caribbean. Other nearby nations or territories, such as the United States, are not members (although the US Commonwealth of Puerto Rico has observer status, and the United States Virgin Islands announced in 2007 they would seek ties with CARICOM). Bermuda, at roughly a thousand miles from the Caribbean Sea, has little trade with, and little economically in common with, the region, and joined primarily to strengthen cultural links.
Try to answer this question if possible: What other member states belong to the Caribbean?
Answer: unanswerable

Input: Read this: Partly because of low sanitation coverage about 17,000 children die each year because of diarrhoea. Another challenge is low cost recovery due to water tariffs that are among the lowest in the world. This in turn requires government subsidies even for operating costs, a situation that has been aggravated by salary increases without tariff increases after the Arab Spring. Poor operation of facilities, such as water and wastewater treatment plants, as well as limited government accountability and transparency, are also issues.
Question: Due to low waer tariffs, what is required to maintain water treatment operation?

Output:
government subsidies
