instruction:
This task is about writing a correct answer for the reading comprehension task. Based on the information provided in a given passage, you should identify the shortest continuous text span from the passage that serves as an answer to the given question. Avoid answers that are incorrect or provides incomplete justification for the question.
question:
Passage: In response to Cusumano's perspective, Screen Producers Australia executive director Matt Deaner clarified the motivation of the film industry: "Distributors are usually wanting to encourage cinema-going as part of this process [monetizing through returns] and restrict the immediate access to online so as to encourage the maximum number of people to go to the cinema." Deaner further explained the matter in terms of the Australian film industry, stating: "there are currently restrictions on quantities of tax support that a film can receive unless the film has a traditional cinema release." Question: Who encourages watching movies at a theater as making money from the film?
answer:
Distributors


question:
Passage: Following the Fourth Crusade and the fall of Constantinople to the "Latins" in 1204 mainland Greece was split between the Greek Despotate of Epirus (a Byzantine successor state) and Frankish rule (known as the Frankokratia), while some islands came under Venetian rule. The re-establishment of the Byzantine imperial capital in Constantinople in 1261 was accompanied by the empire's recovery of much of the Greek peninsula, although the Frankish Principality of Achaea in the Peloponnese and the rival Greek Despotate of Epirus in the north both remained important regional powers into the 14th century, while the islands remained largely under Genoese and Venetian control. Question: Greece was split into sections of different rulers in what year?
answer:
1204


question:
Passage: The current–voltage characteristic of an LED is similar to other diodes, in that the current is dependent exponentially on the voltage (see Shockley diode equation). This means that a small change in voltage can cause a large change in current. If the applied voltage exceeds the LED's forward voltage drop by a small amount, the current rating may be exceeded by a large amount, potentially damaging or destroying the LED. The typical solution is to use constant-current power supplies to keep the current below the LED's maximum current rating. Since most common power sources (batteries, mains) are constant-voltage sources, most LED fixtures must include a power converter, at least a current-limiting resistor. However, the high resistance of three-volt coin cells combined with the high differential resistance of nitride-based LEDs makes it possible to power such an LED from such a coin cell without an external resistor. Question: What is a solution to preventing an LED failure?
answer:

use constant-current power supplies
