input question: I know that the answer to the question "What may affect the choice of an antenna?" is in "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).". Can you tell me what it is????
output answer: feedpoint impedance

I know that the answer to the question "Where are Americans acting as missionaries?" is in "There are many missionary groups operating in the country, including Lutherans, Baptists, Catholics, Grace Brethren, and Jehovah's Witnesses. While these missionaries are predominantly from the United States, France, Italy, and Spain, many are also from Nigeria, the Democratic Republic of the Congo, and other African countries. Large numbers of missionaries left the country when fighting broke out between rebel and government forces in 20023, but many of them have now returned to continue their work.".

Q: I know that the answer to the question "What artists did Madonna not want to immulate during this time?" is in "Madonna's seventh studio album, Ray of Light, (1998) reflected a change in her image. She collaborated with electronica producer William Orbit and wanted to create a sound that could blend dance music with pop and British rock. American music critic Ann Powers explained that what Madonna searched for with Orbit "was a kind of a lushness that she wanted for this record. Techno and rave was happening in the 90's and had a lot of different forms. There was very experimental, more hard stuff like Aphex Twin. There was party stuff like Fatboy Slim. That's not what Madonna wanted for this. She wanted something more like a singer-songwriter, really. And William Orbit provided her with that."". Can you tell me what it is?
A: Aphex Twin. There was party stuff like Fatboy Slim

Can you tell me what it is?
Answer: both have praised the deal

[Q]: I know that the answer to the question "Are bipolar transistors and field-effect transistor identical in how they are wired in a circuit?" is in "There are two types of transistors, which have slight differences in how they are used in a circuit. A bipolar transistor has terminals labeled base, collector, and emitter. A small current at the base terminal (that is, flowing between the base and the emitter) can control or switch a much larger current between the collector and emitter terminals. For a field-effect transistor, the terminals are labeled gate, source, and drain, and a voltage at the gate can control a current between source and drain.". Can you tell me what it is?
****
[A]: have slight differences in how they are used in a circuit
