Input: Read this: Mechanically controlled variable capacitors allow the plate spacing to be adjusted, for example by rotating or sliding a set of movable plates into alignment with a set of stationary plates. Low cost variable capacitors squeeze together alternating layers of aluminum and plastic with a screw. Electrical control of capacitance is achievable with varactors (or varicaps), which are reverse-biased semiconductor diodes whose depletion region width varies with applied voltage. They are used in phase-locked loops, amongst other applications.
Question: What do mechanically controlled variable capacitors enable to be modified?

Output: the plate spacing

QUES: Christian theologians have held idealist views, often based on Neoplatonism, despite the influence of Aristotelian scholasticism from the 12th century onward. Later western theistic idealism such as that of Hermann Lotze offers a theory of the "world ground" in which all things find their unity: it has been widely accepted by Protestant theologians. Several modern religious movements, for example the organizations within the New Thought Movement and the Unity Church, may be said to have a particularly idealist orientation. The theology of Christian Science includes a form of idealism: it teaches that all that truly exists is God and God's ideas; that the world as it appears to the senses is a distortion of the underlying spiritual reality, a distortion that may be corrected (both conceptually and in terms of human experience) through a reorientation (spiritualization) of thought.

QUES: According to Strabo, the Greco-Bactrians seem to have had contacts with China through the silk road trade routes (Strabo, XI.XI.I). Indian sources also maintain religious contact between Buddhist monks and the Greeks, and some Greco-Bactrians did convert to Buddhism. Demetrius, son and successor of Euthydemus, invaded north-western India in 180 BC, after the destruction of the Mauryan empire there; the Mauryans were probably allies of the Bactrians (and Seleucids). The exact justification for the invasion remains unclear, but by about 175 BC, the Greeks ruled over parts of north-western India. This period also marks the beginning of the obfuscation of Greco-Bactrian history. Demetrius possibly died about 180 BC; numismatic evidence suggest the existence of several other kings shortly thereafter. It is probable that at this point that the Greco-Bactrian kingdom split into several semi-independent regions for some years, often warring amongst themselves. Heliocles was the last Greek to clearly rule Bactria, his power collapsing in the face of central Asian tribal invasions (Scythian and Yuezhi), by about 130 BCE. However, Greek urban civilisation seems to have continued in Bactria after the fall of the kingdom, having a hellenising effect on the tribes which had displaced Greek-rule. The Kushan empire which followed continued to use Greek on their coinage and Greeks continued being influential in the empire.
Whose death signifies the beginning of confusing documentation of Greco-Bactrian history?

ANS: Demetrius

Commercial credit and agricultural consumer loans were the main types of loans. The trade credit was usually extended by temples in order to finance trade expeditions and was nominated in silver. The interest rate was set at 1/60 a month (one shekel per mina) some time before 2000 BC and it remained at that level for about two thousand years. Rural loans commonly arose as a result of unpaid obligations due to an institution (such as a temple), in this case the arrears were considered to be lent to the debtor. They were denominated in barley or other crops and the interest rate was typically much higher than for commercial loans and could amount to 1/3 to 1/2 of the loan principal.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What were the main types of loans in Sumerian society?
Ah, so.. Commercial credit and agricultural consumer

Question: Three counties of the Washington District (now part of Tennessee) broke off from North Carolina in 1784 and formed the State of Franklin. Efforts to obtain admission to the Union failed, and the counties (now numbering eight) had re-joined North Carolina by 1789. North Carolina ceded the area to the federal government in 1790, after which it was organized into the Southwest Territory. In an effort to encourage settlers to move west into the new territory, in 1787 the mother state of North Carolina ordered a road to be cut to take settlers into the Cumberland Settlementsfrom the south end of Clinch Mountain (in East Tennessee) to French Lick (Nashville). The Trace was called the "North Carolina Road" or "Avery's Trace", and sometimes "The Wilderness Road" (although it should not be confused with Daniel Boone's "Wilderness Road" through the Cumberland Gap).
Try to answer this question if possible: What was the name given to the land that North Carolina transferred to the federal government in 1790?
Answer: Southwest Territory

Context and question: Mammalian hair, also known as pelage, can vary in color between populations, organisms within a population, and even on the individual organism. Light-dark color variation is common in the mammalian taxa. Sometimes, this color variation is determined by age variation, however, in other cases, it is determined by other factors. Selective pressures, such as ecological interactions with other populations or environmental conditions, often lead to the variation in mammalian coloration. These selective pressures favor certain colors in order to increase survival. Camouflage is thought to be a major selection pressure shaping coloration in mammals, although there is also evidence that sexual selection, communication, and physiological processes may influence the evolution of coloration as well. Camouflage is the most predominant mechanism for color variation, as it aids in the concealment of the organisms from predators or from their prey. Coat color can also be for intraspecies communication such as warning members of their species about predators, indicating health for reproductive purposes, communicating between mother and young, and intimidating predators. Studies have shown that in some cases, differences in female and male coat color could indicate information nutrition and hormone levels, which are important in the mate selection process. One final mechanism for coat color variation is physiological response purposes, such as temperature regulation in tropical or arctic environments. Although much has been observed about color variation, much of the genetic that link coat color to genes is still unknown. The genetic sites where pigmentation genes are found are known to affect phenotype by: 1) altering the spatial distribution of pigmentation of the hairs, and 2) altering the density and distribution of the hairs. Quantitative trait mapping is being used to better understand the distribution of loci responsible for pigmentation variation. However, although the genetic sites are known, there is still much to learn about how these genes are expressed.
Besides Camouflage being a reason for having certain hair colors, what other reasons have been discovered?
Answer:
sexual selection, communication, and physiological processes
