Hypothesis
Definition:
(n.) A supposition; a proposition or principle which is supposed or taken for granted, in order to draw a conclusion or inference for proof of the point in question; something not proved, but assumed for the purpose of argument, or to account for a fact or an occurrence; as, the hypothesis that head winds detain an overdue steamer.
(n.) A tentative theory or supposition provisionally adopted to explain certain facts, and to guide in the investigation of others; hence, frequently called a working hypothesis.
Example Sentences:

(6) The present study was designed to test the hypothesis that the decreased Epi response following ET was due to 1) depletion of adrenal Epi content such that adrenomedullary stimulation would not release Epi, 2) decreased Epi release with direct stimulation, i.e., desensitization of release, or 3) decreased afferent signals generated by ET itself.
