Problem: Following a steady decline, beginning in the late 1990s up through the mid-2000s, illicit drug use among adolescents has been on the rise in the U.S. Aside from alcohol, marijuana is the most commonly indulged drug habit during adolescent years. Data collected by the National Institute on Drug Abuse shows that between the years of 2007 and 2011, marijuana use grew from 5.7% to 7.2% among 8th grade students; among 10th grade students, from 14.2% to 17.6%; and among 12th graders, from 18.8% to 22.6%. Additional, recent years have seen a surge in popularity of MDMA; between 2010 and 2011, the use of MDMA increased from 1.4% to 2.3% among high school seniors. The heightened usage of ecstasy most likely ties in at least to some degree with the rising popularity of rave culture.
The heightened usage of what drug is most likely due at least in some part to the rising popularity of rave culture?

Problem: The Finnish and Baltic invasions began a deterioration of relations between the Soviets and Germany. Stalin's invasions were a severe irritant to Berlin, as the intent to accomplish these was not communicated to the Germans beforehand, and prompted concern that Stalin was seeking to form an anti-German bloc. Molotov's reassurances to the Germans, and the Germans' mistrust, intensified. On June 16, as the Soviets invaded Lithuania, but before they had invaded Latvia and Estonia, Ribbentrop instructed his staff "to submit a report as soon as possible as to whether in the Baltic States a tendency to seek support from the Reich can be observed or whether an attempt was made to form a bloc."
Who never wanted to know the moment an anti-german bloc was to form?

Problem: Widely referred to as Highbury, Arsenal Stadium was the club's home from September 1913 until May 2006. The original stadium was designed by the renowned football architect Archibald Leitch, and had a design common to many football grounds in the UK at the time, with a single covered stand and three open-air banks of terracing. The entire stadium was given a massive overhaul in the 1930s: new Art Deco West and East stands were constructed, opening in 1932 and 1936 respectively, and a roof was added to the North Bank terrace, which was bombed during the Second World War and not restored until 1954.
When did Arsenal FC leave Highbury stadium?
