QUES: Likewise, group theory helps predict the changes in physical properties that occur when a material undergoes a phase transition, for example, from a cubic to a tetrahedral crystalline form. An example is ferroelectric materials, where the change from a paraelectric to a ferroelectric state occurs at the Curie temperature and is related to a change from the high-symmetry paraelectric state to the lower symmetry ferroelectic state, accompanied by a so-called soft phonon mode, a vibrational lattice mode that goes to zero frequency at the transition.
What temperature causes the change of ferroelectric materials?

ANS: Curie temperature

QUES: During the last three decades of the 19th century a proliferation of anthropological societies and associations occurred, most independent, most publishing their own journals, and all international in membership and association. The major theorists belonged to these organizations. They supported the gradual osmosis of anthropology curricula into the major institutions of higher learning. By 1898 the American Association for the Advancement of Science was able to report that 48 educational institutions in 13 countries had some curriculum in anthropology. None of the 75 faculty members were under a department named anthropology.
Who belonged to these proliferating organizations?

ANS: The major theorists

QUES: The outbreak of World War I in 1914 was precipitated by the rise of nationalism in Southeastern Europe as the Great Powers took up sides. The Allies defeated the Central Powers in 1918. During the Paris Peace Conference the Big Four imposed their terms in a series of treaties, especially the Treaty of Versailles.
In what year did World War I begin?

ANS: 1914

QUES: From an institutional perspective, the rules of the House assign a number of specific responsibilities to the minority leader. For example, Rule XII, clause 6, grant the minority leader (or his designee) the right to offer a motion to recommit with instructions; Rule II, clause 6, states the Inspector General shall be appointed by joint recommendation of the Speaker, majority leader, and minority leader; and Rule XV, clause 6, provides that the Speaker, after consultation with the minority leader, may place legislation on the Corrections Calendar. The minority leader also has other institutional duties, such as appointing individuals to certain federal entities.
What rule gives minority leader right to offer motion to recommit with instructions?

ANS:
Rule XII, clause 6
