Article: The first department stores Lane Crawford was opened in 1850 by Scots Thomas Ash Lane and Ninian Crawford on Des Voeux Road, Hong Kong Island. At the beginning, the store mainly catered visiting ships' crews as well as British Navy staff and their families. In 1900, the first ethnic-Chinese owned Sincere Department Store was opened by Ma Ying Piu, who returned from Australia and inspired by David Jones. In 1907, another former Hong Kong expatriate in Australia, the Kwok's family, returned to Hong Kong and founded Wing On.

Question: What year did Lane Crawford open? 
Ans: 1850


Here is a question about this article: He also developed Feynman diagrams, a bookkeeping device that helps in conceptualizing and calculating interactions between particles in spacetime, including the interactions between electrons and their antimatter counterparts, positrons. This device allowed him, and later others, to approach time reversibility and other fundamental processes. Feynman's mental picture for these diagrams started with the hard sphere approximation, and the interactions could be thought of as collisions at first. It was not until decades later that physicists thought of analyzing the nodes of the Feynman diagrams more closely. Feynman painted Feynman diagrams on the exterior of his van.
What is the answer to this question: What did Feynman produce that help in understanding calculations between particles in space and time?
****
So... Feynman diagrams


The problem: Answer a question about this article:
The Twilight Zone Tower of Terror is the common name for a series of elevator attractions at the Disney's Hollywood Studios park in Orlando, the Disney California Adventure Park park in Anaheim, the Walt Disney Studios Park in Paris and the Tokyo DisneySea park in Tokyo. The central element of this attraction is a simulated free-fall achieved through the use of a high-speed elevator system. For safety reasons, passengers are seated and secured in their seats rather than standing. Unlike most traction elevators, the elevator car and counterweight are joined using a rail system in a continuous loop running through both the top and the bottom of the drop shaft. This allows the drive motor to pull down on the elevator car from underneath, resulting in downward acceleration greater than that of normal gravity. The high-speed drive motor is used to rapidly lift the elevator as well.
Do ride goers stand or sit?

The answer: passengers are seated and secured in their seats rather than standing


Problem: Please answer a question about the following article about Cotton:
GM cotton acreage in India grew at a rapid rate, increasing from 50,000 hectares in 2002 to 10.6 million hectares in 2011. The total cotton area in India was 12.1 million hectares in 2011, so GM cotton was grown on 88% of the cotton area. This made India the country with the largest area of GM cotton in the world. A long-term study on the economic impacts of Bt cotton in India, published in the Journal PNAS in 2012, showed that Bt cotton has increased yields, profits, and living standards of smallholder farmers. The U.S. GM cotton crop was 4.0 million hectares in 2011 the second largest area in the world, the Chinese GM cotton crop was third largest by area with 3.9 million hectares and Pakistan had the fourth largest GM cotton crop area of 2.6 million hectares in 2011. The initial introduction of GM cotton proved to be a success in Australia – the yields were equivalent to the non-transgenic varieties and the crop used much less pesticide to produce (85% reduction). The subsequent introduction of a second variety of GM cotton led to increases in GM cotton production until 95% of the Australian cotton crop was GM in 2009 making Australia the country with the fifth largest GM cotton crop in the world. Other GM cotton growing countries in 2011 were Argentina, Myanmar, Burkina Faso, Brazil, Mexico, Colombia, South Africa and Costa Rica.
What percentage of Australia's cotton crop was GM in 2009?
A: 95%


Question: Read this and answer the question

Much media attention on the season had been focused on the three black singers, Fantasia Barrino, LaToya London, and Jennifer Hudson, dubbed the Three Divas. All three unexpectedly landed on the bottom three on the top seven result show, with Hudson controversially eliminated. Elton John, who was one of the mentors that season, called the results of the votes "incredibly racist". The prolonged stays of John Stevens and Jasmine Trias in the finals, despite negative comments from the judges, had aroused resentment, so much so that John Stevens reportedly received a death threat, which he dismissed as a joke 'blown out of proportion'.

What were Fantasia Barrino, LaToya London and Jennifer Hudson called?
Answer: the Three Divas


Stanley Crouch wrote in a New York Daily News piece "Obama's mother is of white U.S. stock. His father is a black Kenyan," in a column entitled "What Obama Isn't: Black Like Me." During the 2008 campaign, the African-American columnist David Ehrenstein of the LA Times accused white liberals of flocking to Obama because he was a "Magic Negro", a term that refers to a black person with no past who simply appears to assist the mainstream white (as cultural protagonists/drivers) agenda. Ehrenstein went on to say "He's there to assuage white 'guilt' they feel over the role of slavery and racial segregation in American history."
What was the title of Crouch's article?
"What Obama Isn't: Black Like Me."
