[EX Q]: Question: Of the subjects Chamberlain studied, which is the study of plants? Passage:Chamberlain then went to Geneva, where he studied under Carl Vogt (a supporter of racial typology at the University of Geneva), Graebe, Müller Argoviensis, Thury, Plantamour, and other professors. He studied systematic botany, geology, astronomy, and later the anatomy and physiology of the human body. Under the tutelage of Professor Julius von Wiesner of the University of Vienna, Chamberlain studied botany in Geneva, earning a Bacheliers en sciences (BSc) physiques et naturelles in 1881. His thesis, Recherches sur la sève ascendante (Studies on rising sap), was not finished until 1897 and did not culminate in a further qualification. The main thrust of Chamberlain's dissertation is that the vertical transport of fluids in vascular plants via xylem cannot be explained by the fluid mechanical theories of the time, but only by the existence of a "vital force" (force vitale) that is beyond the pale of physical measurement. He summarises his thesis in the Introduction: Physical arguments, in particular transpirational pull and root pressure, have since been shown to be adequate for explaining the ascent of sap.
