QUES: In Lemon v. Kurtzman, 403 U.S. 602 (1971), the court determined that a Pennsylvania state policy of reimbursing the salaries and related costs of teachers of secular subjects in private religious schools violated the Establishment Clause. The court's decision argued that the separation of church and state could never be absolute: "Our prior holdings do not call for total separation between church and state; total separation is not possible in an absolute sense. Some relationship between government and religious organizations is inevitable," the court wrote. "Judicial caveats against entanglement must recognize that the line of separation, far from being a "wall," is a blurred, indistinct, and variable barrier depending on all the circumstances of a particular relationship."

Whose salaries were being reimbursed in private religious schools?

QUES: The primary circadian "clock" in mammals is located in the suprachiasmatic nucleus (or nuclei) (SCN), a pair of distinct groups of cells located in the hypothalamus. Destruction of the SCN results in the complete absence of a regular sleep–wake rhythm. The SCN receives information about illumination through the eyes. The retina of the eye contains "classical" photoreceptors ("rods" and "cones"), which are used for conventional vision. But the retina also contains specialized ganglion cells that are directly photosensitive, and project directly to the SCN, where they help in the entrainment (synchronization) of this master circadian clock.

What surrounds the hypothalamus?

QUES: All Iranian languages are descended from a common ancestor, Proto-Iranian. In turn, and together with Proto-Indo-Aryan and the Nuristani languages, Proto-Iranian descends from a common ancestor Proto-Indo-Iranian. The Indo-Iranian languages are thought to have originated in Central Asia. The Andronovo culture is the suggested candidate for the common Indo-Iranian culture ca. 2000 BC.

What other language besides Nuristani this proto-Iranian descent from?
