Please answer this: Given the following passage "Resonant antennas are expected to be used around a particular resonant frequency; an antenna must therefore be built or ordered to match the frequency range of the intended application. A particular antenna design will present a particular feedpoint impedance. While this may affect the choice of an antenna, an antenna's impedance can also be adapted to the desired impedance level of a system using a matching network while maintaining the other characteristics (except for a possible loss of efficiency).", answer the following question. Note that the answer is present within the text. Question: What is required in a wireless communication?

Answer: antenna
Problem: Given the following passage "All paper produced by paper machines as the Fourdrinier Machine are wove paper, i.e. the wire mesh that transports the web leaves a pattern that has the same density along the paper grain and across the grain. Textured finishes, watermarks and wire patterns imitating hand-made laid paper can be created by the use of appropriate rollers in the later stages of the machine.", answer the following question. Note that the answer is present within the text. Question: How are watermarks embedded into the papers?

A: use of appropriate rollers
Problem: Given the question: Given the following passage "Prior to 1917, Turkey used the lunar Islamic calendar with the Hegira era for general purposes and the Julian calendar for fiscal purposes. The start of the fiscal year was eventually fixed at 1 March and the year number was roughly equivalent to the Hegira year (see Rumi calendar). As the solar year is longer than the lunar year this originally entailed the use of "escape years" every so often when the number of the fiscal year would jump. From 1 March 1917 the fiscal year became Gregorian, rather than Julian. On 1 January 1926 the use of the Gregorian calendar was extended to include use for general purposes and the number of the year became the same as in other countries.", answer the following question. Note that the answer is present within the text. Question: When did Turkey no longer use the era originally used with the lunar islamic calendar for year numbers?
++++++++++++++++++++++++++++++++
The answer is:
1 January 1926
input question: Given the following passage "After the First World War, however, it became apparent that the number of mixed-race people was growing at a faster rate than the white population, and by 1930 fear of the "half-caste menace" undermining the White Australia ideal from within was being taken as a serious concern. Dr. Cecil Cook, the Northern Territory Protector of Natives, noted that:", answer the following question. Note that the answer is present within the text.

Given the following passage "Darwin's aims were twofold: to show that species had not been separately created, and to show that natural selection had been the chief agent of change. He knew that his readers were already familiar with the concept of transmutation of species from Vestiges, and his introduction ridicules that work as failing to provide a viable mechanism. Therefore, the first four chapters lay out his case that selection in nature, caused by the struggle for existence, is analogous to the selection of variations under domestication, and that the accumulation of adaptive variations provides a scientifically testable mechanism for evolutionary speciation.", answer the following question. Note that the answer is present within the text. Question: What was the point of natural selection?
----
Answer: change
Q: Given the following passage "In 1945, the first formal women's barbershop organization, Sweet Adelines, was formed.

Headquartered in Tulsa, Oklahoma, the organization encompasses more than 1,200 registered quartets and 600 choruses.", answer the following question. Note that the answer is present within the text. Question: Where are the barbershop groups from?
A:
