Question: Read this and answer the question

In 2006 and 2007, the world used approximately 2.4 megatonnes (5.3×109 lb) of pesticides, with herbicides constituting the biggest part of the world pesticide use at 40%, followed by insecticides (17%) and fungicides (10%). In 2006 and 2007 the U.S. used approximately 0.5 megatonnes (1.1×109 lb) of pesticides, accounting for 22% of the world total, including 857 million pounds (389 kt) of conventional pesticides, which are used in the agricultural sector (80% of conventional pesticide use) as well as the industrial, commercial, governmental and home & garden sectors.Pesticides are also found in majority of U.S. households with 78 million out of the 105.5 million households indicating that they use some form of pesticide. As of 2007, there were more than 1,055 active ingredients registered as pesticides, which yield over 20,000 pesticide products that are marketed in the United States.

On estimate how many megatonnes of pesticides were used between 2006 and 2007?
Answer: approximately 2.4


Problem: From 1950 to 2011, world population increased from 2.5 billion to 7 billion and is forecast to reach a plateau of more than 9 billion during the 21st century. Sir David King, former chief scientific adviser to the UK government, told a parliamentary inquiry: "It is self-evident that the massive growth in the human population through the 20th century has had more impact on biodiversity than any other single factor." At least until the middle of the 21st century, worldwide losses of pristine biodiverse land will probably depend much on the worldwide human birth rate.
Who is the former chief scientific adviser to the UK government?
The answer is the following: Sir David King


Montana has 56 counties with the United States Census Bureau stating Montana's contains 364 "places", broken down into 129 incorporated places and 235 census-designated places. Incorporated places consist of 52 cities, 75 towns, and two consolidated city-counties. Montana has one city, Billings, with a population over 100,000; and two cities with populations over 50,000, Missoula and Great Falls. These three communities are considered the centers of Montana's three Metropolitan Statistical Areas.
What city in Montana has over 100,000 people?
Billings


Input: American Idol
Michael Lynche was the lowest vote getter at top nine and was given the Judges' Save. The next week Katie Stevens and Andrew Garcia were eliminated. That week, Adam Lambert was invited back to be a mentor, the first Idol alum to do so. Idol Gives Back returned this season on April 21, 2010, and raised $45 million.

Which contestant was saved by the judges in season nine of American Idol?
Output: Michael Lynche


Input: Article: On 14 July, Iraqi army officers Abdel Karim Qasim and Abdel Salam Aref overthrew the Iraqi monarchy and, the next day, Iraqi prime minister and Nasser's chief Arab antagonist, Nuri al-Said, was killed. Nasser recognized the new government and stated that "any attack on Iraq was tantamount to an attack on the UAR". On 15 July, US marines landed in Lebanon, and British special forces in Jordan, upon the request of those countries' governments to prevent them from falling to pro-Nasser forces. Nasser felt that the revolution in Iraq left the road for pan-Arab unity unblocked. On 19 July, for the first time, he declared that he was opting for full Arab union, although he had no plan to merge Iraq with the UAR. While most members of the Iraqi Revolutionary Command Council (RCC) favored Iraqi-UAR unity, Qasim sought to keep Iraq independent and resented Nasser's large popular base in the country.

Now answer this question: What anti-Nasser Iraqi was assassinated?

Output: Nuri al-Said


Problem: In the last two decades, photovoltaics (PV), also known as solar PV, has evolved from a pure niche market of small scale applications towards becoming a mainstream electricity source. A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. In 1931 a German engineer, Dr Bruno Lange, developed a photo cell using silver selenide in place of copper oxide. Although the prototype selenium cells converted less than 1% of incident light into electricity, both Ernst Werner von Siemens and James Clerk Maxwell recognized the importance of this discovery. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the crystalline silicon solar cell in 1954. These early solar cells cost 286 USD/watt and reached efficiencies of 4.5–6%. By 2012 available efficiencies exceed 20% and the maximum efficiency of research photovoltaics is over 40%.
Who created the first solar cell using silver selenide in place of copper oxide?
The answer is the following:
Dr Bruno Lange
