Explanation:

• For question 25, the passage focuses on Pasteur's scientific discoveries like vaccines for rabies and anthrax, so it's about his discoveries.
• For question 26, the text mentions Pasteur discovered a vaccine for anthrax and a treatment for humans bitten by a rabid dog (implies rabies - related discovery), and in general context, he is known for germ - related work too, so all of the above.
• For question 27, in a scientific context, a flask is a container used in experiments.
• For question 28, the scientific method includes variables and controls to test hypotheses. Vaccines and germs are not components of the scientific method itself.
• For question 29, "animalcules" historically referred to small creatures that seemed to appear spontaneously.
• For question 30, in Pasteur's experiment with the bent - neck flask, germs could not get to the broth at the bottom of the flask.
