2) Certain research results indicate that listening to this kind of music may induce a short-term improvement on the performance of certain kinds of mental tasks known as spatio-temporal reasoning.

15) X is the collective pseudonym under which a group of (mainly French) 20th-century mathematicians wrote a series of books presenting an exposition of modern advanced mathematics, beginning in 1935. With the goal of founding all of mathematics on set theory, the group strove for utmost rigour and generality, creating some new terminology and concepts along the way. While X is an invented personage, a group carrying his surname is officially known as the Association des collaborateurs de X has an office in Paris. Notations introduced by the group include: the

21) The X hypothesis, proposed by James Lovelock, was first scientifically formulated in the 1960s by Lovelock as a consequence of his work for NASA on methods of detecting life on Mars. It is an ecological hypothesis proposing that the biosphere and the physical components of the Earth (atmosphere, cryosphere, hydrosphere and lithosphere) are closely integrated to form a complex interacting system that maintains the climatic and biogeochemical conditions on Earth in a preferred homeostasis. It was named after the Greek supreme goddess of Earth. The theory was initially, said to be a way to explain the fact that combinations of chemicals including oxygen and methane persist in stable

25) The simplest method to measure temperatue this way is to count the number of _____ in 15 seconds and add 40. The sum usually approximates the temperature within a few degrees Fahrenheit. The original formula for determining temperature from ____ appears to have been published in 1897 by A.E. Dolbear, a physics professor at Tufts College. Since Dolbear’s time, formulas have been devised for various sub-species. For example: Field ______: T = 50 + (N - 40 / 4) Snowy Tree _______: T = 50 + (N - 92 / 4.7) Katydid: T = 60 + (N - 19 / 3)
