よくある間違い：
Learners often confuse 'hypothesis' with 'theory' or 'guess'. A hypothesis is more careful and must be testable. Also note the plural: one hypothesis, two hypotheses (not *hypothesises*). After 'a hypothesis that', use a full clause: 'a hypothesis that stress affects sleep', not 'a hypothesis that stress affecting sleep'.
