Problem: Beyoncé:

In 2006, the animal rights organization People for the Ethical Treatment of Animals (PETA), criticized Beyoncé for wearing and using fur in her clothing line House of Deréon. In 2011, she appeared on the cover of French fashion magazine L'Officiel, in blackface and tribal makeup that drew criticism from the media. A statement released from a spokesperson for the magazine said that Beyoncé's look was "far from the glamorous Sasha Fierce" and that it was "a return to her African roots".

Problem: Pharmaceutical industry:

In March 2001, 40 multi-national pharmaceutical companies brought litigation against South Africa for its Medicines Act, which allowed the generic production of antiretroviral drugs (ARVs) for treating HIV, despite the fact that these drugs were on-patent. HIV was and is an epidemic in South Africa, and ARVs at the time cost between 10,000 and 15,000 USD per patient per year. This was unaffordable for most South African citizens, and so the South African government committed to providing ARVs at prices closer to what people could afford. To do so, they would need to ignore the patents on drugs and produce generics within the country (using a compulsory license), or import them from abroad. After international protest in favour of public health rights (including the collection of 250,000 signatures by MSF), the governments of several developed countries (including The Netherlands, Germany, France, and later the US) backed the South African government, and the case was dropped in April of that year.

How many signatures were collected by ARV?

A: unanswerable


Problem: Iran:

On November 4, 1979, a group of students seized the United States Embassy and took the embassy with 52 personnel and citizens hostage, after the United States refused to return Mohammad Reza Pahlavi to Iran to face trial in the court of the new regime. Attempts by the Jimmy Carter administration to negotiate for the release of the hostages, and a failed rescue attempt, helped force Carter out of office and brought Ronald Reagan to power. On Jimmy Carter's final day in office, the last hostages were finally set free as a result of the Algiers Accords.

Who seized the US Embassy in Iran in 1979?
