Which of the following hypotheses is testable by using the scientific method?
a- all men are mortal
b- the best color is blue
c- no life exists on other planets
d- all swags are white
e- swimming is fun
The hypothesis that all swans are white is testable by science. The presence of just one black swan, for example, would definitively prove that not all swans are white, thus rejecting the initial hypothesis.
