Answer 2

Sure, I'd be happy to help you fill in the blanks with the appropriate articles ("a/an" or "the"):

1. An experiment can help a researcher prove their theory.
2. The antibodies exist in our blood.
3. The project gives free medical care to the poor.
4. The lab is where scientists conduct experiments.
5. The knowledge is the foundation on which science was built.

Please note that in the case of "the poor" and "the lab," we use the definite article "the" because we are referring to specific groups ("the poor") and specific locations ("the lab").
