  • CAn educated guess
  • DThe simplest theory
  • EA statement of truth

Q2:

Which of the following is the best description of a theory?

  • AA hypothesis that is supported by experimental data
  • BA statement of truth about the universe
  • CA guess at what might happen during an experiment
  • DA belief about the way the universe works
  • EA disproven hypothesis

Q3:

Which of the following is the best description of a scientific law?

  • AA statement that is always true, regardless of how many times it is tested
  • BA generally accepted theory supported by experimental data
  • CAn observation of a physical process

  • AThe hypothesis must be proved to be a fact.
  • BThe hypothesis must not be peer-reviewed.
  • CThe hypothesis must explain exactly why something is occurring.
  • DThe hypothesis must be tested multiple times, over many years, by different scientists.
