input question: I know that the answer to the question "What allowed instrument usage increases in the 1500's" is in "Typical stringed instruments of the early period include the harp, lute, vielle, and psaltery, while wind instruments included the flute family (including recorder), shawm (an early member of the oboe family), trumpet, and the bagpipes. Simple pipe organs existed, but were largely confined to churches, although there were portable varieties. Later in the period, early versions of keyboard instruments like the clavichord and harpsichord began to appear. Stringed instruments such as the viol had emerged by the 16th century, as had a wider variety of brass and reed instruments. Printing enabled the standardization of descriptions and specifications of instruments, as well as instruction in their use.". Can you tell me what it is????

input question: I know that the answer to the question "Which happened later, the papacy of Gregory VII, or the Concordat of Worms?" is in "Monastic reform inspired change in the secular church. The ideals that it was based upon were brought to the papacy by Pope Leo IX (pope 10491054), and provided the ideology of the clerical independence that led to the Investiture Controversy in the late 11th century. This involved Pope Gregory VII (pope 107385) and Emperor Henry IV, who initially clashed over episcopal appointments, a dispute that turned into a battle over the ideas of investiture, clerical marriage, and simony. The emperor saw the protection of the Church as one of his responsibilities as well as wanting to preserve the right to appoint his own choices as bishops within his lands, but the papacy insisted on the Church's independence from secular lords. These issues remained unresolved after the compromise of 1122 known as the Concordat of Worms. The dispute represents a significant stage in the creation of a papal monarchy separate from and equal to lay authorities. It also had the permanent consequence of empowering German princes at the expense of the German emperors.". Can you tell me what it is????
output answer: the Concordat of Worms

input question: I know that the answer to the question "What does the indirect method allow artists to do?" is in "The indirect method of applying tesserae is often used for very large projects, projects with repetitive elements or for areas needing site specific shapes. Tiles are applied face-down to a backing paper using an adhesive, and later transferred onto walls, floors or craft projects. This method is most useful for extremely large projects as it gives the maker time to rework areas, allows the cementing of the tiles to the backing panel to be carried out quickly in one operation and helps ensure that the front surfaces of the mosaic tiles and mosaic pieces are flat and in the same plane on the front, even when using tiles and pieces of differing thicknesses. Mosaic murals, benches and tabletops are some of the items usually made using the indirect method, as it results in a smoother and more even surface.". Can you tell me what it is????

input question: I know that the answer to the question "Which of the following is not a Libyan revolutionary group: Black Boots, the Central Intelligence Agency, or the Free Officers Movement?" is in "Idris' government was increasingly unpopular by the latter 1960s; it had exacerbated Libya's traditional regional and tribal divisions by centralising the country's federal system in order to take advantage of the country's oil wealth, while corruption and entrenched systems of patronage were widespread throughout the oil industry. Arab nationalism was increasingly popular, and protests flared up following Egypt's 1967 defeat in the Six-Day War with Israel; allied to the western powers, Idris' administration was seen as pro-Israeli. Anti-western riots broke out in Tripoli and Benghazi, while Libyan workers shut down oil terminals in solidarity with Egypt. By 1969, the U.S. Central Intelligence Agency was expecting segments of Libya's armed forces to launch a coup. Although claims have been made that they knew of Gaddafi's Free Officers Movement, they have since claimed ignorance, stating that they were monitoring Abdul Aziz Shalhi's Black Boots revolutionary group.".
