Please answer this: Extract the answer to the question from the following context. Question: If you need a low slope, what do you use? Context: LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee. Nitride-based LEDs have a fairly steep I/V curve and are useless for this purpose. Although LED forward voltage is far more current-dependent than a Zener diode, Zener diodes with breakdown voltages below 3 V are not widely available.

Answer: Red LEDs
Problem: Extract the answer to the question from the following context. Question: Which is not a last name, States or Madison? Context: Federalism in the United States is the evolving relationship between state governments and the federal government of the United States. American government has evolved from a system of dual federalism to one of associative federalism. In "Federalist No. 46," James Madison asserted that the states and national government "are in fact but different agents and trustees of the people, constituted with different powers." Alexander Hamilton, writing in "Federalist No. 28," suggested that both levels of government would exercise authority to the citizens' benefit: "If their [the peoples'] rights are invaded by either, they can make use of the other as the instrument of redress."

A: States
Problem: Given the question: Extract the answer to the question from the following context. Question: what type of energy is mentioned second? Context: Examples of energy transformation include generating electric energy from heat energy via a steam turbine, or lifting an object against gravity using electrical energy driving a crane motor. Lifting against gravity performs mechanical work on the object and stores gravitational potential energy in the object. If the object falls to the ground, gravity does mechanical work on the object which transforms the potential energy in the gravitational field to the kinetic energy released as heat on impact with the ground. Our Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that in itself (since it still contains the same total energy even if in different forms), but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy.

input question: Extract the answer to the question from the following context. Question: What picked up more support over time? Context: Karl Marx published the Communist Manifesto in February 1848, with little attention. However, a few days later the French Revolution of 1848 broke out, which replaced the monarchy of Louis Philippe with the Second French Republic. In June 1848, Paris workers, disenchanted with the new government, built barricades and raised red flags. The new government called in the French Army to put down the uprising, the first of many such confrontations between the army and the new worker's movements in Europe.???
output answer: Communist Manifesto
Extract the answer to the question from the following context. Question: What event was the reason why coolies were chosen as labour to import? Context: The importation of slaves was made illegal in 1792. Governor Robert Patton (18021807) recommended that the company import Chinese labour to supplement the rural workforce. The coolie labourers arrived in 1810, and their numbers reached 600 by 1818. Many were allowed to stay, and their descendents became integrated into the population. An 1814 census recorded 3,507 people on the island.

Q: Extract the answer to the question from the following context. Question: When was Bod first used in the newer broad sense of the word? Context: The Tibetan name for their land, Bod , means "Tibet" or "Tibetan Plateau", although it originally meant the central region around Lhasa, now known in Tibetan as U. The Standard Tibetan pronunciation of Bod, [p], is transcribed Bho in Tournadre Phonetic Transcription, Bo in the THL Simplified Phonetic Transcription and Poi in Tibetan pinyin. Some scholars believe the first written reference to Bod "Tibet" was the ancient Bautai people recorded in the Egyptian Greek works Periplus of the Erythraean Sea (1st century CE) and Geographia (Ptolemy, 2nd century CE), itself from the Sanskrit form Bhautta of the Indian geographical tradition.
