(a) Interpretation: Whether the statement about the flow of an electric current in the sealed evacuated glass tube is true or false needs to be determined. Concept introduction: J.J. Thomson’s cathode ray experiment showed that all the atoms contains negatively charged subatomic particles, which was given the name “electrons” lately.
