Problem: One of the uses for scales that assess sexual orientation is determining what the prevalence of different sexual orientations are within a population. Depending on subject's age, culture and sex, the prevalence rates of homosexuality vary depending on which component of sexual orientation is being assessed: sexual attraction, sexual behavior, or sexual identity. Assessing sexual attraction will yield the greatest prevalence of homosexuality in a population whereby the proportion of individuals indicating they are same sex attracted is two to three times greater than the proportion reporting same sex behavior or identify as gay, lesbian, or bisexual. Furthermore, reports of same sex behavior usually exceed those of gay, lesbian, or bisexual identification. The following chart demonstrates how widely the prevalence of homosexuality can vary depending on what age, location and component of sexual orientation is being assessed:
What will cause the amount of homosexuality to vary?

Answer: which component of sexual orientation is being assessed


Problem: During the last interglacial period, the Red Sea coast of Eritrea was occupied by early anatomically modern humans. It is believed that the area was on the route out of Africa that some scholars suggest was used by early humans to colonize the rest of the Old World. In 1999, the Eritrean Research Project Team composed of Eritrean, Canadian, American, Dutch and French scientists discovered a Paleolithic site with stone and obsidian tools dated to over 125,000 years old near the Bay of Zula south of Massawa, along the Red Sea littoral. The tools are believed to have been used by early humans to harvest marine resources like clams and oysters.
How long ago was the last interglacial period?

Problem: For any prime number p, there is also the multiplicative group of integers modulo p. Its elements are the integers 1 to p − 1. The group operation is multiplication modulo p. That is, the usual product is divided by p and the remainder of this division is the result of modular multiplication. For example, if p = 5, there are four group elements 1, 2, 3, 4. In this group, 4 · 4 = 1, because the usual product 16 is equivalent to 1, which divided by 5 yields a remainder of 1. for 5 divides 16 − 1 = 15, denoted
