4.
Suppose that a group of scientists accepts a theory as offering a convincing explanation of observable data. Ideally, how should those scientists react to new data that appear to contradict the theory?
a)
They should let the public decide whether the new data are convincing, because science should be democratic.
b)
They should ignore the new data, because the new data are most likely incorrect.
c)
They should accept the new data, because data are facts and facts are more certain than theories.

They should investigate whether the new data are accurate, because every theory is open to analysis.
5.
In the 18th century, scientists argued about whether cells could form spontaneously from nonliving material. In 1749, a scientist named John Needham performed several experiments in which he boiled a broth solution in a container that was then sealed with a cork. After a while, living cells appeared in the broth. Needham concluded that cells could arise from nonliving materials.
Lazzaro Spallanzani performed similar experiments in the 1760s. However, he boiled his broth for a longer time and sealed the neck of the container by melting the glass. Living cells were never generated in his solutions.
What characteristics of scientific knowledge does this passage illustrate?
