Problem: Question: "What color do leaves turn when they stop producing chlorophyll?" Context: "In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin." Answer:

A: red

Problem: Given the question: Question: "Which tourist hotspot in Portugal has a second letter of a?" Context: "Tourist hotspots in Portugal are Lisbon, Algarve, Madeira, Porto and the city of Coimbra, also, between 4-5 million religious pilgrims visit Fatima each year, where apparitions of the Blessed Virgin Mary to three shepherd children reportedly took place in 1917. The Sanctuary of Fatima is one of the largest Roman Catholic shrines in the world. The Portuguese government continues to promote and develop new tourist destinations, such as the Douro Valley, the island of Porto Santo, and Alentejo. Lisbon is the 16th European city which attracts the most tourists (with seven million tourists occupying the city's hotels in 2006, a number that grew 11.8% compared to previous year). Lisbon in recent years surpassed the Algarve as the leading tourist region in Portugal. Porto and Northern Portugal, especially the urban areas north of Douro River valley, was the tourist destination which grew most (11.9%) in 2006, surpassing Madeira (in 2010), as the third most visited destination.[citation needed]" Answer:

input question: Question: "How can more than one amendment pass?" Context: "Similarly, the federal constitutional initiative allows citizens to put a constitutional amendment to a national vote, if 100,000 voters sign the proposed amendment within 18 months.[note 8] Parliament can supplement the proposed amendment with a counter-proposal, and then voters must indicate a preference on the ballot in case both proposals are accepted. Constitutional amendments, whether introduced by initiative or in Parliament, must be accepted by a double majority of the national popular vote and the cantonal popular votes.[note 9]" Answer:???
output answer: voters must indicate a preference on the ballot in case both proposals are accepted

Question: "Which properties of gas can affect the efficiency of a filament?" Context: "While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps." Answer:
----
Answer: molecular weight of the gas and the cross sectional area of the gas molecules

Q: Question: "Napoleon's planned unification of Europe was referred to as?" Context: "Hoping to extend the Continental System, Napoleon invaded Iberia and declared his brother Joseph the King of Spain in 1808. The Spanish and the Portuguese revolted with British support. The Peninsular War lasted six years, noted for its brutal guerrilla warfare, and culminated in an Allied victory. Fighting also erupted in Central Europe, as the Austrians launched another attack against the French in 1809. Napoleon defeated them at the Battle of Wagram, dissolving the Fifth Coalition formed against France. By 1811, Napoleon ruled over 70 million people across an empire that had domination in Europe, which had not witnessed this level of political consolidation since the days of the Roman Empire. He maintained his strategic status through a series of alliances and family appointments. He created a new aristocracy in France while allowing the return of nobles who had been forced into exile by the Revolution." Answer:
A: Continental System

[Q]: Question: "What was announced in the year that comes two years after 2010?" Context: "Reapportionment following the 2010 United States Census gave the state two more seats in the House of Representatives. The legislature's redistricting, announced in 2012, was quickly challenged in court, on the grounds that it had unfairly benefited Republican interests. In 2015, the Florida Supreme Court ruled on appeal that the congressional districts had to be redrawn because of the legislature's violation of the Fair District Amendments to the state constitution passed in 2010; it accepted a new map in early December 2015." Answer:
****
[A]:
The legislature's redistricting
