Problem: Please answer a question about the following article about Antenna (radio):
Maximum power transfer requires matching the impedance of an antenna system (as seen looking into the transmission line) to the complex conjugate of the impedance of the receiver or transmitter. In the case of a transmitter, however, the desired matching impedance might not correspond to the dynamic output impedance of the transmitter as analyzed as a source impedance but rather the design value (typically 50 ohms) required for efficient and safe operation of the transmitting circuitry. The intended impedance is normally resistive but a transmitter (and some receivers) may have additional adjustments to cancel a certain amount of reactance in order to "tweak" the match. When a transmission line is used in between the antenna and the transmitter (or receiver) one generally would like an antenna system whose impedance is resistive and near the characteristic impedance of that transmission line in order to minimize the standing wave ratio (SWR) and the increase in transmission line losses it entails, in addition to supplying a good match at the transmitter or receiver itself.
What is the desired design value for transmmiting circuitry?
A: 50 ohms
Problem: Please answer a question about the following article about House music:
In Britain, further experiments in the genre boosted its appeal. House and rave clubs such as Lakota and Cream emerged across Britain, hosting house and dance scene events. The 'chilling out' concept developed in Britain with ambient house albums such as The KLF's Chill Out and Analogue Bubblebath by Aphex Twin. The Godskitchen superclub brand also began in the midst of the early 90's rave scene. After initially hosting small nights in Cambridge and Northampton, the associated events scaled up in Milton Keynes, Birmingham and Leeds. A new indie dance scene also emerged in the 90's. In New York, bands such as Deee-Lite furthered house's international influence. Two distinctive tracks from this era were the Orb's "Little Fluffy Clouds" (with a distinctive vocal sample from Rickie Lee Jones) and the Happy Mondays' "Wrote for Luck" ("WFL") which was transformed into a dance hit by Vince Clarke.
where was the band deee-lite based?
A: New York
Problem: Please answer a question about the following article about Marshall Islands:
On September 21, 1529, Alvaro de Saavedra Ceron commanded the Spanish ship Florida, on his second attempt to recross the Pacific from the Maluku Islands. He stood off a group of islands from which local inhabitants hurled stones at his ship. These islands, which he named "Los Pintados", may have been Ujelang. On October 1, he found another group of islands where he went ashore for eight days, exchanged gifts with the local inhabitants and took on water. These islands, which he named "Los Jardines", may have been Enewetak or Bikini Atoll.
What group of islands might have been Bikini Atoll or Enewetak?
A: Los Jardines

Portugal (Portuguese: [putua]), officially the Portuguese Republic (Portuguese: Republica Portuguesa), is a country on the Iberian Peninsula, in Southwestern Europe. It is the westernmost country of mainland Europe, being bordered by the Atlantic Ocean to the west and south and by Spain to the north and east. The PortugalSpain border is 1,214 km (754 mi) long and considered the longest uninterrupted border within the European Union. The republic also includes the Atlantic archipelagos of the Azores and Madeira, both autonomous regions with their own regional governments.
