Problem: Queen (band):

The band's sixth studio album News of the World was released in 1977, which has gone four times platinum in the United States, and twice in the UK. The album contained many songs tailor-made for live performance, including two of rock's most recognisable anthems, "We Will Rock You" and the rock ballad "We Are the Champions", both of which became enduring international sports anthems, and the latter reached number four in the US. Queen commenced the News of the World Tour in October 1977, and Robert Hilburn of the Los Angeles Times called this concert tour the band's "most spectacularly staged and finely honed show".

Problem: After the Holocaust, which had been perpetrated by the Nazi Germany and its allies prior to and during World War II, Lemkin successfully campaigned for the universal acceptance of international laws defining and forbidding genocides. In 1946, the first session of the United Nations General Assembly adopted a resolution that "affirmed" that genocide was a crime under international law, but did not provide a legal definition of the crime. In 1948, the UN General Assembly adopted the Convention on the Prevention and Punishment of the Crime of Genocide (CPPCG) which defined the crime of genocide for the first time.
Which group convened officially for the first time in 1948?

There are concerns that antibiotics may increase the risk of hemolytic uremic syndrome in people infected with Escherichia coli O157:H7. In resource-poor countries, treatment with antibiotics may be beneficial. However, some bacteria are developing antibiotic resistance, particularly Shigella. Antibiotics can also cause diarrhea, and antibiotic-associated diarrhea is the most common adverse effect of treatment with general antibiotics.

Question: In 2013 the United States Patent & Trademark Office approximated that the worth of intellectual property to the U.S. economy is more than US$5 trillion and creates employment for an estimated 18 million American people. The value of intellectual property is considered similarly high in other developed nations, such as those in the European Union. In the UK, IP has become a recognised asset class for use in pension-led funding and other types of business finance. However, in 2013, the UK Intellectual Property Office stated: "There are millions of intangible business assets whose value is either not being leveraged at all, or only being leveraged inadvertently".
