Please answer this: Extract the answer to the question from the following context. Question: Which is better for bulk transmission if you want to avoid loss, AC or DC power? Context: There has, however, been interest among railroad operators in returning to DC use at higher voltages than previously used. At the same voltage, DC often has less loss than AC, and for this reason high-voltage direct current is already used on some bulk power transmission lines. DC avoids the electromagnetic radiation inherent with AC, and on a railway this also reduces interference with signalling and communications and mitigates hypothetical EMF risks. DC also avoids the power factor problems of AC. Of particular interest to railroading is that DC can supply constant power with a single ungrounded wire. Constant power with AC requires three-phase transmission with at least two ungrounded wires. Another important consideration is that mains-frequency 3-phase AC must be carefully planned to avoid unbalanced phase loads. Parts of the system are supplied from different phases on the assumption that the total loads of the 3 phases will even out. At the phase break points between regions supplied from different phases, long insulated supply breaks are required to avoid them being shorted by rolling stock using more than one pantograph at a time. A few railroads have tried 3-phase but its substantial complexity has made single-phase standard practice despite the interruption in power flow that occurs twice every cycle. An experimental 6 kV DC railway was built in the Soviet Union.

Problem: Extract the answer to the question from the following context. Question: Of the three founding celebrity investors of Planet Hollywood whose full names are mentioned, which has the longest first name? Context: Schwarzenegger was a founding celebrity investor in the Planet Hollywood chain of international theme restaurants (modeled after the Hard Rock Cafe) along with Bruce Willis, Sylvester Stallone and Demi Moore. Schwarzenegger severed his financial ties with the business in early 2000. Schwarzenegger said the company had not had the success he had hoped for, claiming he wanted to focus his attention on "new US global business ventures" and his movie career.

A: Sylvester Stallone

Problem: Given the question: Extract the answer to the question from the following context. Question: How are consonants sometimes communicated? Context: So-called voiced aspirated consonants are nearly always pronounced instead with breathy voice, a type of phonation or vibration of the vocal folds. The modifier letter after a voiced consonant actually represents a breathy-voiced or murmured dental stop, as with the "voiced aspirated" bilabial stop b in the Indo-Aryan languages. This consonant is therefore more accurately transcribed as b, with the diacritic for breathy voice, or with the modifier letter b, a superscript form of the symbol for the voiced glottal fricative .

The answer is:
voiced

input question: Extract the answer to the question from the following context. Question: What's disallowed in Australia? Context: Incandescent bulbs have been replaced in many applications by other types of electric light, such as fluorescent lamps, compact fluorescent lamps (CFL), cold cathode fluorescent lamps (CCFL), high-intensity discharge lamps, and light-emitting diode lamps (LED). Some jurisdictions, such as the European Union, China, Canada and United States, are in the process of phasing out the use of incandescent light bulbs while others, including Colombia, Mexico, Cuba, Argentina, Brazil and Australia, have prohibited them already.???
output answer: incandescent light bulbs

Extract the answer to the question from the following context. Question: Where have the figures represented been collected? Context: The climate of Saint Helena is tropical, marine and mild, tempered by the Benguela Current and trade winds that blow almost continuously. The climate varies noticeably across the island. Temperatures in Jamestown, on the north leeward shore, range between 2128 C (7082 F) in the summer (January to April) and 1724 C (6375 F) during the remainder of the year. The temperatures in the central areas are, on average, 56 C (9.010.8 F) lower. Jamestown also has a very low annual rainfall, while 7501,000 mm (3039 in) falls per year on the higher ground and the south coast, where it is also noticeably cloudier. There are weather recording stations in the Longwood and Blue Hill districts.

Q: Extract the answer to the question from the following context. Question: Why is Tucson running part of its share of Cap water into local rivers to seep into their aquifer? Context: In an effort to conserve water, Tucson is recharging groundwater supplies by running part of its share of CAP water into various open portions of local rivers to seep into their aquifer. Additional study is scheduled to determine the amount of water that is lost through evaporation from the open areas, especially during the summer. The City of Tucson already provides reclaimed water to its inhabitants, but it is only used for "applications such as irrigation, dust control, and industrial uses." These resources have been in place for more than 27 years, and deliver to over 900 locations.
