Problem: Cotton:

But Bt cotton is ineffective against many cotton pests, however, such as plant bugs, stink bugs, and aphids; depending on circumstances it may still be desirable to use insecticides against these. A 2006 study done by Cornell researchers, the Center for Chinese Agricultural Policy and the Chinese Academy of Science on Bt cotton farming in China found that after seven years these secondary pests that were normally controlled by pesticide had increased, necessitating the use of pesticides at similar levels to non-Bt cotton and causing less profit for farmers because of the extra expense of GM seeds. However, a 2009 study by the Chinese Academy of Sciences, Stanford University and Rutgers University refuted this. They concluded that the GM cotton effectively controlled bollworm. The secondary pests were mostly miridae (plant bugs) whose increase was related to local temperature and rainfall and only continued to increase in half the villages studied. Moreover, the increase in insecticide use for the control of these secondary insects was far smaller than the reduction in total insecticide use due to Bt cotton adoption. A 2012 Chinese study concluded that Bt cotton halved the use of pesticides and doubled the level of ladybirds, lacewings and spiders. The International Service for the Acquisition of Agri-biotech Applications (ISAAA) said that, worldwide, GM cotton was planted on an area of 25 million hectares in 2011. This was 69% of the worldwide total area planted in cotton.

How much GM cotton was planted in 2009?

Problem: Pubs often have traditional names. A common name is the "Marquis of Granby". These pubs were named after John Manners, Marquess of Granby, who was the son of John Manners, 3rd Duke of Rutland and a general in the 18th century British Army. He showed a great concern for the welfare of his men, and on their retirement, provided funds for many of them to establish taverns, which were subsequently named after him. All pubs granted their licence in 1780 were called the Royal George[citation needed], after King George III, and the twentieth anniversary of his coronation.
What was the military rank of the 3rd Duke of Rutland?

Answer: general

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The easternmost section, about 10 miles (16 km) in width, consists of hilly land that runs along the western bank of the Tennessee River. To the west of this narrow strip of land is a wide area of rolling hills and streams that stretches all the way to the Mississippi River; this area is called the Tennessee Bottoms or bottom land. In Memphis, the Tennessee Bottoms end in steep bluffs overlooking the river. To the west of the Tennessee Bottoms is the Mississippi Alluvial Plain, less than 300 feet (90 m) above sea level. This area of lowlands, flood plains, and swamp land is sometimes referred to as the Delta region. Memphis is the economic center of West Tennessee and the largest city in the state.
What geographical region lies west of the Tennessee bottom land?
A: Mississippi Alluvial Plain

Context and question: The City of Charleston is served by the Charleston International Airport. It is located in the City of North Charleston and is about 12 miles (20 km) northwest of downtown Charleston. It is the busiest passenger airport in South Carolina (IATA: CHS, ICAO: KCHS).

Charleston Executive Airport is a smaller airport located in the John's Island section of the city of Charleston and is used by noncommercial aircraft. Both airports are owned and operated by the Charleston County Aviation Authority.
The Charleston International Airport is located in what city?
Answer: North Charleston

Question: Early Modern universities initially continued the curriculum and research of the Middle Ages: natural philosophy, logic, medicine, theology, mathematics, astronomy (and astrology), law, grammar and rhetoric. Aristotle was prevalent throughout the curriculum, while medicine also depended on Galen and Arabic scholarship. The importance of humanism for changing this state-of-affairs cannot be underestimated. Once humanist professors joined the university faculty, they began to transform the study of grammar and rhetoric through the studia humanitatis. Humanist professors focused on the ability of students to write and speak with distinction, to translate and interpret classical texts, and to live honorable lives. Other scholars within the university were affected by the humanist approaches to learning and their linguistic expertise in relation to ancient texts, as well as the ideology that advocated the ultimate importance of those texts. Professors of medicine such as Niccolo Leoniceno, Thomas Linacre and William Cop were often trained in and taught from a humanist perspective as well as translated important ancient medical texts. The critical mindset imparted by humanism was imperative for changes in universities and scholarship. For instance, Andreas Vesalius was educated in a humanist fashion before producing a translation of Galen, whose ideas he verified through his own dissections. In law, Andreas Alciatus infused the Corpus Juris with a humanist perspective, while Jacques Cujas humanist writings were paramount to his reputation as a jurist. Philipp Melanchthon cited the works of Erasmus as a highly influential guide for connecting theology back to original texts, which was important for the reform at Protestant universities. Galileo Galilei, who taught at the Universities of Pisa and Padua, and Martin Luther, who taught at the University of Wittenberg (as did Melanchthon), also had humanist training. The task of the humanists was to slowly permeate the university; to increase the humanist presence in professorships and chairs, syllabi and textbooks so that published works would demonstrate the humanistic ideal of science and scholarship.
Is there an answer to this question: Galileo Galilei was a professor of what subject?

Answer: unanswerable

Drawing from his own experiences in Scouting, Spielberg helped the Boy Scouts of America develop a merit badge in cinematography in order to help promote filmmaking as a marketable skill. The badge was launched at the 1989 National Scout Jamboree, which Spielberg attended, and where he personally counseled many boys in their work on requirements. That same year, 1989, saw the release of Indiana Jones and the Last Crusade. The opening scene shows a teenage Indiana Jones in scout uniform bearing the rank of a Life Scout. Spielberg stated he made Indiana Jones a Boy Scout in honor of his experience in Scouting. For his career accomplishments, service to others, and dedication to a new merit badge Spielberg was awarded the Distinguished Eagle Scout Award.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was Spielberg's merit badge launched?
Ah, so..
1989
