West's controversial incident the following year at the 2009 MTV Video Music Awards was arguably his biggest controversy, and led to widespread outrage throughout the music industry. During the ceremony, West crashed the stage and grabbed the microphone from winner Taylor Swift in order to proclaim that, instead, Beyoncé's video for "Single Ladies (Put a Ring on It)", nominated for the same award, was "one of the best videos of all time". He was subsequently withdrawn from the remainder of the show for his actions. West's tour with Lady Gaga was cancelled in response to the controversy, and it was suggested that the incident was partially responsible for 808s & Heartbreak's lack of nominations at the 52nd Grammy Awards.

What awards ceremony did Kanye not receive any nominations for after the MTV controversy?
Answer: 52nd Grammy Awards


Problem: The most important demographic influence in the modern Portuguese seems to be the oldest one; current interpretation of Y-chromosome and mtDNA data suggests that the Portuguese have their origin in Paleolithic peoples that began arriving to the European continent around 45,000 years ago. All subsequent migrations did leave an impact, genetically and culturally, but the main population source of the Portuguese is still Paleolithic. Genetic studies show Portuguese populations not to be significantly different from other European populations.
In what group of people do the Portuguese have their origin?
The answer is the following: Paleolithic peoples

Input: Economy of Greece
After fourteen consecutive years of economic growth, Greece went into recession in 2008. By the end of 2009, the Greek economy faced the highest budget deficit and government debt-to-GDP ratios in the EU. After several upward revisions, the 2009 budget deficit is now estimated at 15.7% of GDP. This, combined with rapidly rising debt levels (127.9% of GDP in 2009) led to a precipitous increase in borrowing costs, effectively shutting Greece out of the global financial markets and resulting in a severe economic crisis.

When did Greece go into recession?
Output: in 2008
