Problem: Brains are most simply compared in terms of their size. The relationship between brain size, body size and other variables has been studied across a wide range of vertebrate species. As a rule, brain size increases with body size, but not in a simple linear proportion. In general, smaller animals tend to have larger brains, measured as a fraction of body size. For mammals, the relationship between brain volume and body mass essentially follows a power law with an exponent of about 0.75. This formula describes the central tendency, but every family of mammals departs from it to some degree, in a way that reflects in part the complexity of their behavior. For example, primates have brains 5 to 10 times larger than the formula predicts. Predators tend to have larger brains than their prey, relative to body size.
Which group of animals have brains 5-10 times larger than the formula predicts?
The answer is the following: primates

Problem: The events of the summer of 1974 dominate the politics on the island, as well as Greco-Turkish relations. Around 150,000 settlers from Turkey are believed to be living in the north—many of whom were forced from Turkey by the Turkish government—in violation of the Geneva Convention and various UN resolutions. Following the invasion and the capture of its northern territory by Turkish troops, the Republic of Cyprus announced that all of its ports of entry in the north were closed, as they were effectively not under its control.[citation needed]
What terms did the Turkish government violate by sending people?
The answer is the following: Geneva Convention and various UN resolutions

Problem: By 1976, Queen were back in the studio recording A Day at the Races, which is often regarded as a sequel album to A Night at the Opera. It again borrowed the name of a Marx Brothers movie, and its cover was similar to that of A Night at the Opera, a variation on the same Queen Crest. The most recognisable of the Marx Brothers, Groucho Marx, invited Queen to visit him in his Los Angeles home in March 1977; there the band thanked him in person, and performed "'39" a cappella. Musically, A Day at the Races was by both fans' and critics' standards a strong effort, reaching number one in the UK and Japan, and number five in the US. The major hit on the album was "Somebody to Love", a gospel-inspired song in which Mercury, May, and Taylor multi-tracked their voices to create a 100-voice gospel choir. The song went to number two in the UK, and number thirteen in the US. The album also featured one of the band's heaviest songs, May's "Tie Your Mother Down", which became a staple of their live shows.
Which comedian invited Queen to visit him in 1977? 
The answer is the following: Groucho Marx

Problem: Despite delays in some countries, the number of European HD channels and viewers has risen steadily since the first HDTV broadcasts, with SES's annual Satellite Monitor market survey for 2010 reporting more than 200 commercial channels broadcasting in HD from Astra satellites, 185 million HD capable TVs sold in Europe (£60 million in 2010 alone), and 20 million households (27% of all European digital satellite TV homes) watching HD satellite broadcasts (16 million via Astra satellites).
According to the 2010 Satellite Monitor market survey, how many European households were watching HD broadcasts? 
The answer is the following:
20 million
