Given a paragraph from a Wikipedia article about some topic, and a question related to the topic, determine whether the question is answerable from the paragraph. If the question is answerable, answer "True", otherwise, answer "False".

[Q]: Bohr also introduced the quantity , now known as the reduced Planck constant, as the quantum of angular momentum. At first, Bohr thought that this was the angular momentum of each electron in an atom: this proved incorrect and, despite developments by Sommerfeld and others, an accurate description of the electron angular momentum proved beyond the Bohr model. The correct quantization rules for electrons in which the energy reduces to the Bohr model equation in the case of the hydrogen atom were given by Heisenberg's matrix mechanics in 1925 and the Schrodinger wave equation in 1926: the reduced Planck constant remains the fundamental quantum of angular momentum. In modern terms, if J is the total angular momentum of a system with rotational invariance, and Jz the angular momentum measured along any given direction, these quantities can only take on the values Question: Who disproved the original belief about plank constant?
[A]: True

[Q]: It is remarkable that the inner heartwood of old trees remains as sound as it usually does, since in many cases it is hundreds, and in a few instances thousands, of years old. Every broken limb or root, or deep wound from fire, insects, or falling timber, may afford an entrance for decay, which, once started, may penetrate to all parts of the trunk. The larvae of many insects bore into the trees and their tunnels remain indefinitely as sources of weakness. Whatever advantages, however, that sapwood may have in this connection are due solely to its relative age and position. Question: What could seep into a tree?
[A]: True

[Q]: The majority of Paris' salaried employees fill 370,000 businesses services jobs, concentrated in the north-western 8th, 16th and 17th arrondissements. Paris' financial service companies are concentrated in the central-western 8th and 9th arrondissement banking and insurance district. Paris' department store district in the 1st, 6th, 8th and 9th arrondissements employ 10 percent of mostly female Paris workers, with 100,000 of these registered in the retail trade. Fourteen percent of Parisians work in hotels and restaurants and other services to individuals. Nineteen percent of Paris employees work for the State in either in administration or education. The majority of Paris' healthcare and social workers work at the hospitals and social housing concentrated in the peripheral 13th, 14th, 18th, 19th and 20th arrondissements. Outside Paris, the western Hauts-de-Seine department La Defense district specialising in finance, insurance and scientific research district, employs 144,600, and the north-eastern Seine-Saint-Denis audiovisual sector has 200 media firms and 10 major film studios. Question: What is the second highest concentration of workforce category listed?
[A]:
True
