Problem: Text: An acoustic-electric guitar (also called an electro-acoustic guitar) is an acoustic guitar fitted with a magnetic pickup, a piezoelectric pickup or a microphone. In electric-acoustic nylon string guitars, piezoelectric pickups and microphones are always used because magnetic pickups are not capable of picking up vibrations of non-magnetic materials. The design is distinct from a semi-acoustic guitar, which is an electric guitar but with the addition of sound chambers within the guitar body. Usually, acoustic-electric guitars are fitted with piezoelectric pickups, and hence require a preamplifier incorporated into the guitar body to amplify the signal before it travels to the main guitar amplifier. These preamps may also come with tone controls of varying types, but usually equalizers with up to six frequency bands are used. They are also referred to as a ''plug-in acoustic guitar'', due to their ability to simply ''plug in'' to a speaker system without the need for microphones.

Question: can a guitar be both acoustic and electric?
A: yes

Problem: Text: Of the thirteen presidential elections from 1956 to 2004, nine featured the incumbent president; the other four (1960, 1968, 1988, 2000) all featured the incumbent vice president. Former vice presidents also ran in 1984 (Walter Mondale) and in 1968 (Richard Nixon, against the incumbent vice president, Hubert Humphrey). The presidential election of 2008 was the first presidential election since 1928 that saw neither an incumbent president nor an incumbent or former vice president take part in any primary or general election for the presidency on a major party ticket. Nixon is the only vice president to have been elected president while not an incumbent, as well as the only person elected twice to both the presidency and vice presidency.

Question: can a current vice president run for president?
A: yes

Problem: Text: A tablespoon is a large spoon used for serving or eating. In many English-speaking regions, the term now refers to a large spoon used for serving, however, in some regions, including parts of Canada, it is the largest type of spoon used for eating. By extension, the term is used as a measure of volume in cooking. In this capacity, it is most commonly abbreviated tbsp or T, and occasionally referred to as a tablespoonful to distinguish it from the utensil. The unit of measurement varies by region: a United States tablespoon is approximately 14.8 ml (0.50 US fl oz), a United Kingdom and Canadian tablespoon is exactly 15 ml (0.51 US fl oz), and an Australian tablespoon is 20 ml (0.68 US fl oz). The capacity of the utensil (as opposed to the measurement) is not defined by law or custom and bears no particular relation to the measurement.

Question: is an american tablespoon the same as uk?
