Here is a question about this article: Sociologists and criminologists have not reached consensus on the explanation for the dramatic decrease in the city's crime rate. Some attribute the phenomenon to new tactics used by the NYPD, including its use of CompStat and the broken windows theory. Others cite the end of the crack epidemic and demographic changes, including from immigration. Another theory is that widespread exposure to lead pollution from automobile exhaust, which can lower intelligence and increase aggression levels, incited the initial crime wave in the mid-20th century, most acutely affecting heavily trafficked cities like New York. A strong correlation was found demonstrating that violent crime rates in New York and other big cities began to fall after lead was removed from American gasoline in the 1970s. Another theory cited to explain New York City's falling homicide rate is the inverse correlation between the number of murders and the increasingly wetter climate in the city.
What is the answer to this question: Being exposed to what type of pollution has been theorized to increase aggression?
****
So... lead

On December 30, 1922, with the creation of the Soviet Union, Russia became one of six republics within the federation of the Union of Soviet Socialist Republics.

How many republics were in the USSR?

The answer: six


Problem: Please answer a question about the following article about Adolescence:
The formal study of adolescent psychology began with the publication of G. Stanley Hall's "Adolescence in 1904." Hall, who was the first president of the American Psychological Association, viewed adolescence primarily as a time of internal turmoil and upheaval (sturm und drang). This understanding of youth was based on two then new ways of understanding human behavior: Darwin's evolutionary theory and Freud's psychodynamic theory. He believed that adolescence was a representation of our human ancestors' phylogenetic shift from being primitive to being civilized. Hall's assertions stood relatively uncontested until the 1950s when psychologists such as Erik Erikson and Anna Freud started to formulate their theories about adolescence. Freud believed that the psychological disturbances associated with youth were biologically based and culturally universal while Erikson focused on the dichotomy between identity formation and role fulfillment. Even with their different theories, these three psychologists agreed that adolescence was inherently a time of disturbance and psychological confusion. The less turbulent aspects of adolescence, such as peer relations and cultural influence, were left largely ignored until the 1980s. From the '50s until the '80s, the focus of the field was mainly on describing patterns of behavior as opposed to explaining them.
Who was the first president of the American Psychological Association?
A: G. Stanley Hall


Question: Read this and answer the question

In 1985, Madonna commented that the first song to ever make a strong impression on her was "These Boots Are Made for Walkin'" by Nancy Sinatra; she said it summed up her own "take-charge attitude". As a young woman, she attempted to broaden her taste in literature, art, and music, and during this time became interested in classical music. She noted that her favorite style was baroque, and loved Mozart and Chopin because she liked their "feminine quality". Madonna's major influences include Karen Carpenter, The Supremes and Led Zeppelin, as well as dancers Martha Graham and Rudolf Nureyev. She also grew up listening to David Bowie, whose show was the first rock concert she ever attended.

Whose favorite style is baroque?
Answer: Madonna


Problem: On December 12, the Supreme Soviet of the Russian SFSR formally ratified the Belavezha Accords and renounced the 1922 Union Treaty. The Russian deputies were also recalled from the Supreme Soviet of the USSR. The legality of this action was questionable, since Soviet law did not allow a republic to unilaterally recall its deputies. However, no one in either Russia or the Kremlin objected. Any objections from the latter would have likely had no effect, since the Soviet government had effectively been rendered impotent long before December. In effect, the largest and most powerful republic had seceded from the Union. Later that day, Gorbachev hinted for the first time that he was considering stepping down.
When were the Belavezha Accords ratified?
The answer is the following: December 12


Input: Article: The early settlement was often subject to attack from sea and land, including periodic assaults from Spain and France (both of whom contested England's claims to the region), and pirates. These were combined with raids by Native Americans, who tried to protect themselves from so-called European "settlers," who in turn wanted to expand the settlement. The heart of the city was fortified according to a 1704 plan by Governor Johnson. Except those fronting Cooper River, the walls were largely removed during the 1720s.

Now answer this question: Which group raided the settlement as a means to protect themselves from settlers?

Output:
Native Americans
