Question: In 1867, the university opened the first private nonsectarian law school west of the Mississippi River. By 1882, Washington University had expanded to numerous departments, which were housed in various buildings across St. Louis. Medical classes were first held at Washington University in 1891 after the St. Louis Medical College decided to affiliate with the University, establishing the School of Medicine. During the 1890s, Robert Sommers Brookings, the president of the Board of Trustees, undertook the tasks of reorganizing the university's finances, putting them onto a sound foundation, and buying land for a new campus.
Is there an answer to this question: What was the first private sectarian school west of the Mississippi River?

Answer: unanswerable

Question: In the fifth century Strasbourg was occupied successively by Alemanni, Huns, and Franks. In the ninth century it was commonly known as Strazburg in the local language, as documented in 842 by the Oaths of Strasbourg. This trilingual text contains, alongside texts in Latin and Old High German (teudisca lingua), the oldest written variety of Gallo-Romance (lingua romana) clearly distinct from Latin, the ancestor of Old French. The town was also called Stratisburgum or Strateburgus in Latin, from which later came Strossburi in Alsatian and Straburg in Standard German, and then Strasbourg in French. The Oaths of Strasbourg is considered as marking the birth of the two countries of France and Germany with the division of the Carolingian Empire.
Is there an answer to this question: In what year did Old French start to be used?

Answer: unanswerable

Question: There exist two different spin isomers of hydrogen diatomic molecules that differ by the relative spin of their nuclei. In the orthohydrogen form, the spins of the two protons are parallel and form a triplet state with a molecular spin quantum number of 1 (12+12); in the parahydrogen form the spins are antiparallel and form a singlet with a molecular spin quantum number of 0 (1212). At standard temperature and pressure, hydrogen gas contains about 25% of the para form and 75% of the ortho form, also known as the "normal form". The equilibrium ratio of orthohydrogen to parahydrogen depends on temperature, but because the ortho form is an excited state and has a higher energy than the para form, it is unstable and cannot be purified. At very low temperatures, the equilibrium state is composed almost exclusively of the para form. The liquid and gas phase thermal properties of pure parahydrogen differ significantly from those of the normal form because of differences in rotational heat capacities, as discussed more fully in spin isomers of hydrogen. The ortho/para distinction also occurs in other hydrogen-containing molecules or functional groups, such as water and methylene, but is of little significance for their thermal properties.
Is there an answer to this question: What percent of ortho form does hydrogen gas contain?

Answer: 75%

Question: A hunter-gatherer is a human living in a society in which most or all food is obtained by foraging (collecting wild plants and pursuing wild animals), in contrast to agricultural societies, which rely mainly on domesticated species.
