Article: 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.

Question: What did the 2012 study say was doubled by the use of GM cotton?
Ans: ladybirds, lacewings and spiders

Article: 1855: Georgian coast: Omar Pasha, the Turkish commander at Crimea had long wanted to land in Georgia, but the western powers vetoed it. When they relented in August most of the campaigning season was lost. In September 8000 Turks landed at Batum, but the main concentration was at Sukhum Kale. This required a 100-mile march south through a country with poor roads. The Russians planned to hold the line of the Ingur River which separates Abkhazia from Georgia proper. Omar crossed the Ingur on 7 November and then wasted a great deal of time, the Russians doing little. By 2 December he had reached the Tskhenis-dzqali, the rainy season had started, his camps were submerged in mud and there was no bread. Learning of the fall of Kars he withdrew to the Ingur. The Russians did nothing and he evacuated to Batum in February of the following year.

Question: Who vetoed Omar Pasha from landing in Georgia?
Ans: the western powers

Ans: bad air quality and pollution

Article: The College's endowment is sub-divided into three distinct portfolios: (i) Unitised Scheme a unit trust vehicle for College, Faculties and Departments to invest endowments and unfettered income to produce returns for the long term; (ii) Non-Core Property a portfolio containing around 120 operational and developmental properties which College has determined are not core to the academic mission; and (iii) Strategic Asset Investments containing College's shareholding in Imperial Innovations and other restricted equity holdings. During the year 2014/15, the market value of the endowment increased by 78 million (18%) to 512.4 million on 31 July 2015.

Question: How many percent did the college's endowment market value increase from 2014 to 2015?
Ans:
18%
