    27.Which of the following best describes Deborah
    A.Creative but inconsistent. B.Conventional but warm.
    C.Innovative and compassionate. D.Sociable and adventurous.
    C
    When Alexander Fleming returned to his lab in 1928,he found a bacteria culture he had grown was infected by fungus(霉菌),killing any colonies it touched.Rather than simply starting over,Fleming switched his focus to the fungus.He identified the bacteria-killing substance,which he called“penicillin,”and seemingly in a single stroke,created the new field of antibiotics(抗生素).
    That's how most people see innovation:A.flash of brilliance and Eureka!,a new world is born.The truth,however,is messier.It wasn't until 1943 that penicillin came into widespread use.
    To put Fleming's discovery in context,consider Ignaz Semmelweis,who pioneered hand washing in maternity wards(产房), significantly reducing childbed fever but receiving scorn instead of fame.That was because in the 1850s,his ideas conflicted with the popular miasma theory,which attributed disease to "bad airs."After his death in 1865,germ theory was accepted,paving the way for Fleming's later work.
