Input: Read this: Erich Koch headed the East Prussian Nazi party from 1928. He led the district from 1932. This period was characterized by efforts to collectivize the local agriculture and ruthlessness in dealing with his critics inside and outside the Party. He also had long-term plans for mass-scale industrialization of the largely agricultural province. These actions made him unpopular among the local peasants. In 1932 the local paramilitary SA had already started to terrorise their political opponents. On the night of 31 July 1932 there was a bomb attack on the headquarters of the Social Democrats in Konigsberg, the Otto-Braun-House. The Communist politician Gustav Sauf was killed; the executive editor of the Social Democrat "Konigsberger Volkszeitung", Otto Wyrgatsch, and the German People's Party politician Max von Bahrfeldt were severely injured. Members of the Reichsbanner were attacked and the local Reichsbanner Chairman of Lotzen, Kurt Kotzan, was murdered on 6 August 1932.

Input: Read this: While there is some dispute as to the matter of influence, Popper had a long-standing and close friendship with economist Friedrich Hayek, who was also brought to the London School of Economics from Vienna. Each found support and similarities in the other's work, citing each other often, though not without qualification. In a letter to Hayek in 1944, Popper stated, "I think I have learnt more from you than from any other living thinker, except perhaps Alfred Tarski." Popper dedicated his Conjectures and Refutations to Hayek. For his part, Hayek dedicated a collection of papers, Studies in Philosophy, Politics, and Economics, to Popper, and in 1982 said, "...ever since his Logik der Forschung first came out in 1934, I have been a complete adherent to his general theory of methodology."

Input: Read this: During the development of a tree, the lower limbs often die, but may remain attached for a time, sometimes years. Subsequent layers of growth of the attaching stem are no longer intimately joined with the dead limb, but are grown around it. Hence, dead branches produce knots which are not attached, and likely to drop out after the tree has been sawn into boards.
Question: Are the knots that dead tree limbs form attached or not attached?

Output: not attached
