Problem: Namibia:

South West Africa became known as Namibia by the UN when the General Assembly changed the territory's name by Resolution 2372 (XXII) of 12 June 1968. In 1978 the UN Security Council passed UN Resolution 435 which planned a transition toward independence for Namibia. Attempts to persuade South Africa to agree to the plan's implementation were not successful until 1988 when the transition to independence finally started under a diplomatic agreement between South Africa, Angola and Cuba, with the USSR and the USA as observers, under which South Africa agreed to withdraw and demobilise its forces in Namibia. As a result, Cuba agreed to pull back its troops in southern Angola sent to support the MPLA in its war for control of Angola with UNITA.

Among which countries had been trying to persuade South Africa to give Namibia independence?

Problem: In the late 19th century with the discovery of the electron, and in the early 20th century, with the discovery of the atomic nucleus, and the birth of particle physics, matter was seen as made up of electrons, protons and neutrons interacting to form atoms. Today, we know that even protons and neutrons are not indivisible, they can be divided into quarks, while electrons are part of a particle family called leptons. Both quarks and leptons are elementary particles, and are currently seen as being the fundamental constituents of matter.
What do atoms form?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Ancient rock paintings in Somalia which date back to 5000 years have been found in the northern part of the country, depicting early life in the territory. The most famous of these is the Laas Geel complex, which contains some of the earliest known rock art on the African continent and features many elaborate pastoralist sketches of animal and human figures. In other places, such as the northern Dhambalin region, a depiction of a man on a horse is postulated as being one of the earliest known examples of a mounted huntsman.
Where does a notable rock painting of a man on horseback exist?
A: the northern Dhambalin region

Context and question: Dissatisfaction with the conduct of the war was growing with the public in the UK and in other countries, aggravated by reports of fiascos, especially the humiliating defeat of the Charge of the Light Brigade at the Battle of Balaclava. On Sunday, 21 January 1855, a "snowball riot" occurred in Trafalgar Square near St. Martin-in-the-Field in which 1,500 people gathered to protest against the war by pelting buses, cabs, and pedestrians with snow balls. When the police intervened, the snowballs were directed at them. The riot was finally put down by troops and police acting with truncheons. In Parliament, Tories demanded an accounting of all soldiers, cavalry and sailors sent to the Crimea and accurate figures as to the number of casualties that had been sustained by all British armed forces in the Crimea; they were especially concerned with the Battle of Balaclava. When Parliament passed a bill to investigate by the vote of 305 to 148, Aberdeen said he had lost a vote of no confidence and resigned as prime minister on 30 January 1855. The veteran former Foreign Secretary Lord Palmerston became prime minister. Palmerston took a hard line; he wanted to expand the war, foment unrest inside the Russian Empire, and permanently reduce the Russian threat to Europe. Sweden and Prussia were willing to join the UK and France, and Russia was isolated.:400402, 406408
What were the people using during the protest?
Answer: snowballs

Question: Lester Brown states that the market "does not incorporate the indirect costs of providing goods or services into prices, it does not value nature's services adequately, and it does not respect the sustainable-yield thresholds of natural systems". It also favors the near term over the long term, thereby showing limited concern for future generations. Tax and subsidy shifting can help overcome these problems, though is also problematic to combine different international normative regimes regulating this issue.
Is there an answer to this question: Lester Brown states that the market does not incorporate what?

Answer: the indirect costs of providing goods or services into prices

Problem: Richard Feynman:

Following the completion of his PhD in 1942, Feynman held an appointment at the University of WisconsinMadison as an assistant professor of physics. The appointment was spent on leave for his involvement in the Manhattan project. In 1945, he received a letter from Dean Mark Ingraham of the College of Letters and Science requesting his return to UW to teach in the coming academic year. His appointment was not extended when he did not commit to return. In a talk given several years later at UW, Feynman quipped, "It's great to be back at the only university that ever had the good sense to fire me."

Who told Feynman to never return to teaching?

A:
