Question: Read this and answer the question

Loop antennas consist of a loop or coil of wire. Loops with circumference of a wavelength or larger act similarly to dipole antennas. However loops small in comparison to a wavelength act differently. They interact with the magnetic field of the radio wave instead of the electric field as other antennas do, and so are relatively insensitive to nearby electrical noise. However they have low radiation resistance, and so are inefficient for transmitting. They are used as receiving antennas at low frequencies, and also as direction finding antennas.

What type of antenna can be formed by a circular segment of wire?
Answer: Loop antennas


Problem: Cyprus was placed under British administration based on Cyprus Convention in 1878 and formally annexed by Britain in 1914. Even though Turkish Cypriots made up only 18% of the population, the partition of Cyprus and creation of a Turkish state in the north became a policy of Turkish Cypriot leaders and Turkey in the 1950s. Turkish leaders for a period advocated the annexation of Cyprus to Turkey as Cyprus was considered an "extension of Anatolia" by them; while since the 19th century, the majority Greek Cypriot population and its Orthodox church had been pursuing union with Greece, which became a Greek national policy in the 1950s. Following nationalist violence in the 1950s, Cyprus was granted independence in 1960. In 1963, the 11-year intercommunal violence between Greek Cypriots and Turkish Cypriots started, which displaced more than 25,000 Turkish Cypriots and brought the end of Turkish Cypriot representation in the republic. On 15 July 1974, a coup d'état was staged by Greek Cypriot nationalists and elements of the Greek military junta in an attempt at enosis, the incorporation of Cyprus into Greece. This action precipitated the Turkish invasion of Cyprus, which led to the capture of the present-day territory of Northern Cyprus the following month, after a ceasefire collapsed, and the displacement of over 150,000 Greek Cypriots and 50,000 Turkish Cypriots. A separate Turkish Cypriot state in the north was established in 1983. These events and the resulting political situation are matters of a continuing dispute.
What year did the intercommunal violence between Greek and Cypriots occur?
The answer is the following: 1963


Switzerland has a dense network of cities, where large, medium and small cities are complementary. The plateau is very densely populated with about 450 people per km2 and the landscape continually shows signs of human presence. The weight of the largest metropolitan areas, which are Zürich, Geneva–Lausanne, Basel and Bern tend to increase. In international comparison the importance of these urban areas is stronger than their number of inhabitants suggests. In addition the two main centers of Zürich and Geneva are recognized for their particularly great quality of life.
What does the weight of the largest metropolitan areas tend to do?
increase


Input: Protestantism
The Plymouth Brethren are a conservative, low church, evangelical movement, whose history can be traced to Dublin, Ireland, in the late 1820s, originating from Anglicanism. Among other beliefs, the group emphasizes sola scriptura. Brethren generally see themselves not as a denomination, but as a network, or even as a collection of overlapping networks, of like-minded independent churches. Although the group refused for many years to take any denominational name to itself—a stance that some of them still maintain—the title The Brethren, is one that many of their number are comfortable with in that the Bible designates all believers as brethren.

What belief is the emphasis of the Plymouth Brethren?
Output: sola scriptura


Input: Article: So an additional problem beyond canceling the unwanted reactance is of matching the remaining resistive impedance to the characteristic impedance of the transmission line. In principle this can always be done with a transformer, however the turns ratio of a transformer is not adjustable. A general matching network with at least two adjustments can be made to correct both components of impedance. Matching networks using discrete inductors and capacitors will have losses associated with those components, and will have power restrictions when used for transmitting. Avoiding these difficulties, commercial antennas are generally designed with fixed matching elements or feeding strategies to get an approximate match to standard coax, such as 50 or 75 Ohms. Antennas based on the dipole (rather than vertical antennas) should include a balun in between the transmission line and antenna element, which may be integrated into any such matching network.

Now answer this question: A general matching network needs a minimum of how many adjustments to correct all components of impedance?

Output: two adjustments


Problem: During the administration of U.S. President Martin Van Buren, nearly 17,000 Cherokees—along with approximately 2,000 black slaves owned by Cherokees—were uprooted from their homes between 1838 and 1839 and were forced by the U.S. military to march from "emigration depots" in Eastern Tennessee (such as Fort Cass) toward the more distant Indian Territory west of Arkansas. During this relocation an estimated 4,000 Cherokees died along the way west. In the Cherokee language, the event is called Nunna daul Isunyi—"the Trail Where We Cried." The Cherokees were not the only American Indians forced to emigrate as a result of the Indian removal efforts of the United States, and so the phrase "Trail of Tears" is sometimes used to refer to similar events endured by other American Indian peoples, especially among the "Five Civilized Tribes". The phrase originated as a description of the earlier emigration of the Choctaw nation.
Which Native American nation's emigration was first associated with the term "Trail of Tears?"
The answer is the following:
Choctaw
