From at least the late nineteenth century in Europe, there was speculation that the range of human sexual response looked more like a continuum than two or three discrete categories. Berlin sexologist Magnus Hirschfeld published a scheme in 1896 that measured the strength of an individual's sexual desire on two independent 10-point scales, A (homosexual) and B (heterosexual). A heterosexual individual may be A0, B5; a homosexual individual may be A5, B0; an asexual would be A0, B0; and someone with an intense attraction to both sexes would be A9, B9.
How many points were on each scale?
A: 10-point

The soft AC format may soon be facing the demographic pressures that the jazz and big band formats faced in the 1960s and 1970s and that the oldies format is starting to face today, with the result that one may hear soft AC less on over-the-air radio and more on satellite radio systems in coming years. Much of the music and artists that were traditionally played on soft AC stations have been relegated to the adult standards format, which is itself disappearing because of aging demographics. Some soft AC stations have found a niche by incorporating more oldies into their playlists and are more open to playing softer songs that fit the "traditional" definition of AC.
Certain soft AC stations have found a niche on the radio by doing what?
A: incorporating more oldies

The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on the US market. The FDA received authority to regulate advertising of prescription drugs and to establish good manufacturing practices. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.
What did the National Academy of Science's study discover?
A: nearly 40 percent of these products were not effective
