Problem: Black people is a term used in certain countries, often in socially based systems of racial classification or of ethnicity, to describe persons who are perceived to be dark-skinned compared to other given populations. As such, the meaning of the expression varies widely both between and within societies, and depends significantly on context. For many other individuals, communities and countries, "black" is also perceived as a derogatory, outdated, reductive or otherwise unrepresentative label, and as a result is neither used nor defined.
Do some countries have negative feelings towards the word "black"?

Problem: In China, a call to boycott French hypermart Carrefour from May 1 began spreading through mobile text messaging and online chat rooms amongst the Chinese over the weekend from April 12, accusing the company's major shareholder, the LVMH Group, of donating funds to the Dalai Lama. There were also calls to extend the boycott to include French luxury goods and cosmetic products. Chinese protesters organized boycotts of the French-owned retail chain Carrefour in major Chinese cities including Kunming, Hefei and Wuhan, accusing the French nation of pro-secessionist conspiracy and anti-Chinese racism. Some burned French flags, some added Swastika (due to its conotaions with Nazism) to the French flag, and spread short online messages calling for large protests in front of French consulates and embassy. Some shoppers who insisted on entering one of the Carrefour stores in Kunming were blocked by boycotters wielding large Chinese flags and hit by water bottles. Hundreds of people joined Anti-French rallies in Beijing, Wuhan, Hefei, Kunming and Qingdao, which quickly spread to other cities like Xi'an, Harbin and Jinan. Carrefour denied any support or involvement in the Tibetan issue, and had its staff in its Chinese stores wear uniforms emblazoned with the Chinese national flag and caps with Olympic insignia and as well as the words "Beijing 2008" to show its support for the games. The effort had to be ceased when the BOCOG deemed the use of official Olympic insignia as illegal and a violation of copyright.
Boycotters accused France of being pro-seccessionist and what?
The answer is the following: anti-Chinese racism.

Problem: Nutritionism is the view that excessive reliance on food science and the study of nutrition can lead to poor nutrition and to ill health. It was originally credited to Gyorgy Scrinis, and was popularized by Michael Pollan. Since nutrients are invisible, policy makers rely on nutrition experts to advise on food choices. Because science has an incomplete understanding of how food affects the human body, Pollan argues, nutritionism can be blamed for many of the health problems relating to diet in the Western World today.
Who has to rely on nutrition experts when it comes to making decisions regarding food and nutritional values?
The answer is the following: policy makers

Problem: 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.
Where did Feynman paint his diagrams?
The answer is the following:
his van
