A Yagi-Uda array uses passive elements to greatly increase gain. It is built along a support boom that is pointed toward the signal, and thus sees no induced signal and does not contribute to the antenna's operation. The end closer to the source is referred to as the front. Near the rear is a single active element, typically a half-wave dipole or folded dipole. Passive elements are arranged in front (directors) and behind (reflectors) the active element along the boom. The Yagi has the inherent quality that it becomes increasingly directional, and thus has higher gain, as the number of elements increases. However, this also makes it increasingly sensitive to changes in frequency; if the signal frequency changes, not only does the active element receive less energy directly, but all of the passive elements adding to that signal also decrease their output as well and their signals no longer reach the active element in-phase.
What is the name for passive elements nearer to the source of the signal?
A: directors

More contemporary views along the evolutionary psychology spectrum posit that both basic emotions and social emotions evolved to motivate (social) behaviors that were adaptive in the ancestral environment. Current research[citation needed] suggests that emotion is an essential part of any human decision-making and planning, and the famous distinction made between reason and emotion is not as clear as it seems. Paul D. MacLean claims that emotion competes with even more instinctive responses, on one hand, and the more abstract reasoning, on the other hand. The increased potential in neuroimaging has also allowed investigation into evolutionarily ancient parts of the brain. Important neurological advances were derived from these perspectives in the 1990s by Joseph E. LeDoux and António Damásio.
What technology has disallowed for research into the earlier-evolved parts of the brain?
A: unanswerable

Conflict with Arius and Arianism as well as successive Roman emperors shaped Athanasius's career. In 325, at the age of 27, Athanasius began his leading role against the Arians as his bishop's assistant during the First Council of Nicaea. Roman emperor Constantine the Great had convened the council in May–August 325 to address the Arian position that the Son of God, Jesus of Nazareth, is of a distinct substance from the Father. Three years after that council, Athanasius succeeded his mentor as archbishop of Alexandria. In addition to the conflict with the Arians (including powerful and influential Arian churchmen led by Eusebius of Nicomedia), he struggled against the Emperors Constantine, Constantius II, Julian the Apostate and Valens. He was known as "Athanasius Contra Mundum" (Latin for Athanasius Against the World).
How many years after the First Council of Nicaea did Athanasius become pope?
A: unanswerable

Political and economic relations were drastically influenced by these theories as the concept of the guild was subordinated to the theory of free trade, and Roman Catholic dominance of theology was increasingly challenged by Protestant churches subordinate to each nation-state, which also (in a fashion the Roman Catholic Church often decried angrily) preached in the vulgar or native language of each region. However, the enlightenment was an outright attack on religion, particularly Christianity. The most outspoken critic of the church in France was François Marie Arouet de Voltaire, a representative figure of the enlightenment. After Voltaire, religion would never be the same again in France.
After the concept of the guild, what happened to religion in France?
A:
unanswerable
