QUES: The oak forests of the southern and central Appalachians consist largely of black, northern red, white, chestnut and scarlet oaks (Quercus velutina, Q. rubra, Q. alba, Q. prinus and Q. coccinea) and hickories, such as the pignut (Carya glabra) in particular. The richest forests, which grade into mesic types, usually in coves and on gentle slopes, have dominantly white and northern red oaks, while the driest sites are dominated by chestnut oak, or sometimes by scarlet or northern red oaks. In the northern Appalachians the oaks, except for white and northern red, drop out, while the latter extends farthest north.

Where do black oaks primarily thrive?

QUES: Serious American students of theology and divinity, particularly in New England, regarded Hebrew as a classical language, along with Greek and Latin, and essential for study of the Old Testament in the original words. The Reverend Ezra Stiles, president of the College from 1778 to 1795, brought with him his interest in the Hebrew language as a vehicle for studying ancient Biblical texts in their original language (as was common in other schools), requiring all freshmen to study Hebrew (in contrast to Harvard, where only upperclassmen were required to study the language) and is responsible for the Hebrew phrase (Urim and Thummim) on the Yale seal. Stiles' greatest challenge occurred in July 1779 when hostile British forces occupied New Haven and threatened to raze the College. However, Yale graduate Edmund Fanning, Secretary to the British General in command of the occupation, interceded and the College was saved. Fanning later was granted an honorary degree LL.D., at 1803, for his efforts.
When was Ezra Stiles president of Yale?

According to research published in 1999 by Alan Green and the Center for Public Integrity (CPI), loopholes in the ESA are commonly exploited in the exotic pet trade. Although the legislation prohibits interstate and foreign transactions for list species, no provisions are made for in-state commerce, allowing these animals to be sold to roadside zoos and private collectors. Additionally, the ESA allows listed species to be shipped across state lines as long as they are not sold. According to Green and the CPI, this allows dealers to "donate" listed species through supposed "breeding loans" to anyone, and in return they can legally receive a reciprocal monetary "donation" from the receiving party. Furthermore, an interview with an endangered species specialist at the US Fish and Wildlife Service revealed that the agency does not have sufficient staff to perform undercover investigations, which would catch these false "donations" and other mislabeled transactions.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What allows exploitation of interstate commerce regulations?
Ah, so.. the ESA allows listed species to be shipped across state lines as long as they are not sold

Question: The earliest written form of the Germanic word God (always, in this usage, capitalized) comes from the 6th-century Christian Codex Argenteus.

The reconstructed Proto-Indo-European form * ghu-to-m was likely based on the root * ghau()-, which meant either "to call" or "to invoke". The Germanic words for God were originally neuterapplying to both gendersbut during the process of the Christianization of the Germanic peoples from their indigenous Germanic paganism, the words became a masculine syntactic form.
Try to answer this question if possible: What was the Argenteus usage based on?
Answer: unanswerable
