Given the following passage  "A necessary condition for the aforementioned reciprocity property is that the materials in the antenna and transmission medium are linear and reciprocal. Reciprocal (or bilateral) means that the material has the same response to an electric current or magnetic field in one direction, as it has to the field or current in the opposite direction. Most materials used in antennas meet these conditions, but some microwave antennas use high-tech components such as isolators and circulators, made of nonreciprocal materials such as ferrite. These can be used to give the antenna a different behavior on receiving than it has on transmitting, which can be useful in applications like radar.",  answer the following question. Note that the answer is present within the text.  Question: What are isolators found in microwave antennas made of?
----
Answer: nonreciprocal materials such as ferrite

Q: Given the following passage  "Instead, it is often desired to have an antenna whose impedance does not vary so greatly over a certain bandwidth. It turns out that the amount of reactance seen at the terminals of a resonant antenna when the frequency is shifted, say, by 5%, depends very much on the diameter of the conductor used. A long thin wire used as a half-wave dipole (or quarter wave monopole) will have a reactance significantly greater than the resistive impedance it has at resonance, leading to a poor match and generally unacceptable performance. Making the element using a tube of a diameter perhaps 1/50 of its length, however, results in a reactance at this altered frequency which is not so great, and a much less serious mismatch which will only modestly damage the antenna's net performance. Thus rather thick tubes are typically used for the solid elements of such antennas, including Yagi-Uda arrays.",  answer the following question. Note that the answer is present within the text.  Question: What causes a reactance of 5%?
A: frequency is shifted

Question: Given the following passage  "To Popper, who was an anti-justificationist, traditional philosophy is misled by the false principle of sufficient reason. He thinks that no assumption can ever be or needs ever to be justified, so a lack of justification is not a justification for doubt. Instead, theories should be tested and scrutinised. It is not the goal to bless theories with claims of certainty or justification, but to eliminate errors in them. He writes, "there are no such things as good positive reasons; nor do we need such things [...] But [philosophers] obviously cannot quite bring [themselves] to believe that this is my opinion, let alone that it is right" (The Philosophy of Karl Popper, p. 1043)",  answer the following question. Note that the answer is present within the text.  Question: According to Popper, what can we never have when it comes to theories?
Answer: certainty or justification

[Q]: Given the following passage  "Evolution had less obvious applications to anatomy and morphology, and at first had little impact on the research of the anatomist Thomas Henry Huxley. Despite this, Huxley strongly supported Darwin on evolution; though he called for experiments to show whether natural selection could form new species, and questioned if Darwin's gradualism was sufficient without sudden leaps to cause speciation. Huxley wanted science to be secular, without religious interference, and his article in the April 1860 Westminster Review promoted scientific naturalism over natural theology, praising Darwin for "extending the domination of Science over regions of thought into which she has, as yet, hardly penetrated" and coining the term "Darwinism" as part of his efforts to secularise and professionalise science. Huxley gained influence, and initiated the X Club, which used the journal Nature to promote evolution and naturalism, shaping much of late Victorian science. Later, the German morphologist Ernst Haeckel would convince Huxley that comparative anatomy and palaeontology could be used to reconstruct evolutionary genealogies.",  answer the following question. Note that the answer is present within the text.  Question: Haeckel would interact with someone whose expertise was in?
****
[A]: anatomy

input: Please answer the following: Given the following passage  "On February 17, 2010, AF1 announced it would use the "Arena Football League" name. The league announced plans for the upcoming season and details of its contract with NFL Network to broadcast AFL games in 2010. AF1 teams were given the option of restoring historical names to their teams. In addition to the historical teams, the league added two new expansion franchises, the Dallas Vigilantes and the Jacksonville Sharks.",  answer the following question. Note that the answer is present within the text.  Question: A football team not from Texas is?
++++++++++
output: Jacksonville Sharks
