Q: Extract the answer to the question from the following context. Question: What is the difference between genome size and number of genes? Context: The genome size, and the number of genes it encodes varies widely between organisms. The smallest genomes occur in viruses (which can have as few as 2 protein-coding genes), and viroids (which act as a single non-coding RNA gene). Conversely, plants can have extremely large genomes, with rice containing >46,000 protein-coding genes. The total number of protein-coding genes (the Earth's proteome) is estimated to be 5 million sequences.
A: The smallest genomes occur in viruses

Q: Extract the answer to the question from the following context. Question: What is an alternative location for classical music from the Boston Symphony Hall? Context: Music is cherished in Boston. The Boston Symphony Orchestra is one of the "Big Five," a group of the greatest American orchestras, and the classical music magazine Gramophone called it one of the "world's best" orchestras. Symphony Hall (located west of Back Bay) is home to the Boston Symphony Orchestra, (and the related Boston Youth Symphony Orchestra, which is the largest youth orchestra in the nation) and the Boston Pops Orchestra. The British newspaper The Guardian called Boston Symphony Hall "one of the top venues for classical music in the world," adding that "Symphony Hall in Boston was where science became an essential part of concert hall design." Other concerts are held at the New England Conservatory's Jordan Hall. The Boston Ballet performs at the Boston Opera House. Other performing-arts organizations located in the city include the Boston Lyric Opera Company, Opera Boston, Boston Baroque (the first permanent Baroque orchestra in the US), and the Handel and Haydn Society (one of the oldest choral companies in the United States). The city is a center for contemporary classical music with a number of performing groups, several of which are associated with the city's conservatories and universities. These include the Boston Modern Orchestra Project and Boston Musica Viva. Several theaters are located in or near the Theater District south of Boston Common, including the Cutler Majestic Theatre, Citi Performing Arts Center, the Colonial Theater, and the Orpheum Theatre.

Q: Extract the answer to the question from the following context. Question: What was determined in 1975 regarding A Night at the Opera? Context: In late 1975, Queen recorded and released A Night at the Opera, taking its name from the popular Marx Brothers movie. At the time, it was the most expensive album ever produced. Like its predecessor, the album features diverse musical styles and experimentation with stereo sound. In "The Prophet's Song", an eight-minute epic, the middle section is a canon, with simple phrases layered to create a full-choral sound. The Mercury penned ballad, "Love of My Life", featured a harp and overdubbed vocal harmonies. The album was very successful in Britain, and went triple platinum in the United States. The British public voted it the 13th greatest album of all time in a 2004 Channel 4 poll. It has also ranked highly in international polls; in a worldwide Guinness poll, it was voted the 19th greatest of all time, while an ABC poll saw the Australian public vote it the 28th greatest of all time. A Night at the Opera has frequently appeared in "greatest albums" lists reflecting the opinions of critics. Among other accolades, it was ranked number 16 in Q Magazine's "The 50 Best British Albums Ever" in 2004, and number 11 in Rolling Stone's "The 100 Greatest Albums of All Time" as featured in their Mexican edition in 2004. It was also placed at No. 230 on Rolling Stone magazine's list of "The 500 Greatest Albums of All Time" in 2003. A Night at the Opera is the third and final Queen album to be featured in the book 1001 Albums You Must Hear Before You Die.

Q: Extract the answer to the question from the following context. Question: What coverts water into electricity for europeans? Context: The Alps provide lowland Europe with drinking water, irrigation, and hydroelectric power. Although the area is only about 11 percent of the surface area of Europe, the Alps provide up to 90 percent of water to lowland Europe, particularly to arid areas and during the summer months. Cities such as Milan depend on 80 percent of water from Alpine runoff. Water from the rivers is used in over 500 hydroelectricity power plants, generating as much as 2900 kilowatts of electricity.
A:
500 hydroelectricity power plants
