Problem: Text: Puerto Ricans are by law natural-born citizens of the United States and may move freely between the island and the mainland. As it is not a state, Puerto Rico does not have a vote in the United States Congress, which governs the territory with full jurisdiction under the Puerto Rico Federal Relations Act of 1950. As a U.S. territory, American citizens residing on the island are disenfranchised at the national level and do not vote for president and vice president of the United States, and do not pay federal income tax on Puerto Rican income. Congress approved a local constitution, allowing U.S. citizens on the territory to elect a governor. A 2012 referendum showed a majority (54% of those who voted) disagreed with ''the present form of territorial status''. A second question asking about a new model, had full statehood the preferred option among those who voted for a change of status, although a significant number of people did not answer the second question of the referendum. Another fifth referendum was held on June 11, 2017, with ''Statehood'' and ''Independence/Free Association'' initially as the only available choices. At the recommendation of the Department of Justice, an option for the ''current territorial status'' was added. The referendum showed an overwhelming support for statehood, with 97.18% voting for it, although the voter turnout had a historically low figure of only 22.99% of the registered voters casting their ballots.

Question: does the island of puerto rico pay federal income tax?

Problem: Text: A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. Unlike an incandescent lamp controlled by a dimmer, each of the filaments operates at full voltage, so the color of the light does not change between the three steps of light available. Certain compact fluorescent lamp bulbs are designed to replace 3-way incandescent bulbs, and have an extra contact and circuitry to bring about similar light level. In recent years, LED three way bulbs have become available as well.

Question: can you use a one way bulb in a three way socket?
A: no

Problem: Text: North America occupies the northern portion of the landmass generally referred to as the New World, the Western Hemisphere, the Americas, or simply America (which, less commonly, is considered by some as a single continent with North America a subcontinent). North America's only land connection to South America is at the Isthmus of Panama. The continent is delimited on the southeast by most geographers at the Darien watershed along the Colombia-Panama border, placing all of Panama within North America. Alternatively, some geologists physiographically locate its southern limit at the Isthmus of Tehuantepec, Mexico, with Central America extending southeastward to South America from this point. The Caribbean islands, or West Indies, are considered part of North America. The continental coastline is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay. Others include the Gulf of Saint Lawrence and the Gulf of California.

Question: are the west indies part of north america?
A:
yes
