Here is a question about this article: In February 2010 Shell and Cosan formed a 50:50 joint-venture, Raizen, comprising all of Cosan's Brazilian ethanol, energy generation, fuel distribution and sugar activities, and all of Shell's Brazilian retail fuel and aviation distribution businesses. In March 2010, Shell announced the sale of some of its assets, including its liquid petroleum gas (LPG) business, to meet the cost of a planned $28bn capital spending programme. Shell invited buyers to submit indicative bids, due by 22 March, with a plan to raise $23bn from the sale. In June 2010, Royal Dutch Shell agreed to acquire all the business of East Resources for a cash consideration of $4.7 billion. The transaction included East Resources' tight gas fields.
What is the answer to this question: What was the name of the 50:50 joint venture formed by Shell and Cosan?
****
So... Raizen

The problem: Answer a question about this article:
No one party to a treaty can impose its particular interpretation of the treaty upon the other parties. Consent may be implied, however, if the other parties fail to explicitly disavow that initially unilateral interpretation, particularly if that state has acted upon its view of the treaty without complaint. Consent by all parties to the treaty to a particular interpretation has the legal effect of adding another clause to the treaty this is commonly called an 'authentic interpretation'.
Consent by all parties to a treaty to a particular interpretation of the treaty has what legal effect?
****
The answer: adding another clause to the treaty

Problem: Please answer a question about the following article about American Idol:
From seasons four to seven and nine, the twenty-four semi-finalists were divided by gender in order to ensure an equal gender division in the top twelve. The men and women sang separately on consecutive nights, and the bottom two in each groups were eliminated each week until only six of each remained to form the top twelve.
How many women were semi-finalists on season six of American Idol?
A: twelve

During the five-years from the end of 2004 through 2009, worldwide renewable energy capacity grew at rates of 1060 percent annually for many technologies. In 2011, UN under-secretary general Achim Steiner said: "The continuing growth in this core segment of the green economy is not happening by chance. The combination of government target-setting, policy support and stimulus funds is underpinning the renewable industry's rise and bringing the much needed transformation of our global energy system within reach." He added: "Renewable energies are expanding both in terms of investment, projects and geographical spread. In doing so, they are making an increasing contribution to combating climate change, countering energy poverty and energy insecurity".

Between what years did worldwide renewable energy capacity grow at rates of 10 to 60 percent annually?
Answer: 2004 through 2009

Problem: Copper's greater conductivity versus other metals enhances the electrical energy efficiency of motors. This is important because motors and motor-driven systems account for 43%-46% of all global electricity consumption and 69% of all electricity used by industry. Increasing the mass and cross section of copper in a coil increases the electrical energy efficiency of the motor. Copper motor rotors, a new technology designed for motor applications where energy savings are prime design objectives, are enabling general-purpose induction motors to meet and exceed National Electrical Manufacturers Association (NEMA) premium efficiency standards.
What percentage of electrical consumption does motor systems use in industry?
The answer is the following: 69%

Input: Article: In contrast, Botswana has recently been forced to ban trophy hunting following a precipitous wildlife decline. The numbers of antelope plummeted across Botswana, with a resultant decline in predator numbers, while elephant numbers remained stable and hippopotamus numbers rose. According to the government of Botswana, trophy hunting is at least partly to blame for this, but many other factors, such as poaching, drought and habitat loss are also to blame. Uganda recently did the same, arguing that "the share of benefits of sport hunting were lopsided and unlikely to deter poaching or improve [Uganda's] capacity to manage the wildlife reserves."

Now answer this question: What animal numbers have increased in Botswana?

Output:
hippopotamus
