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.

Any individual made a member of the Order for gallantry could wear an emblem of two crossed silver oak leaves on the same riband, ribbon or bow as the badge. It could not be awarded posthumously and was effectively replaced in 1974 with the Queen's Gallantry Medal. If recipients of the Order of the British Empire for Gallantry received promotion within the Order, whether for gallantry or otherwise, they continued to wear also the insignia of the lower grade with the oak leaves. However, they only used the post-nominal letters of the higher grade.
Who could wear a emblem of two crossed silver oak leaves?
A: Any individual made a member of the Order for gallantry

Scientific "Materialism" is often synonymous with, and has so far been described, as being a reductive materialism. In recent years, Paul and Patricia Churchland have advocated a radically contrasting position (at least, in regards to certain hypotheses); eliminativist materialism holds that some mental phenomena simply do not exist at all, and that talk of those mental phenomena reflects a totally spurious "folk psychology" and introspection illusion. That is, an eliminative materialist might suggest that a concept like "belief" simply has no basis in fact - the way folk science speaks of demon-caused illnesses. Reductive materialism being at one end of a continuum (our theories will reduce to facts) and eliminative materialism on the other (certain theories will need to be eliminated in light of new facts), Revisionary materialism is somewhere in the middle.
Paul and Patricia disagree with what hypotheses? 
A: unanswerable

The Gospel of Luke begins its account of Mary's life with the Annunciation, when the angel Gabriel appeared to her and announced her divine selection to be the mother of Jesus. According to gospel accounts, Mary was present at the Crucifixion of Jesus and is depicted as a member of the early Christian community in Jerusalem. According to Apocryphal writings, at some time soon after her death, her incorrupt body was assumed directly into Heaven, to be reunited with her soul, and the apostles thereupon found the tomb empty; this is known in Christian teaching as the Assumption.
Which angel appeared to Mary?
A:
Gabriel
