Thank you for your help. I made three sentences using the sturctures A + noun, The + noun, and a plural noun.

Are the subjects in the sentences all in generic use?

These sentences would be better if they were active instead of passive!

1 and 3 seem generic to me, but 2 seems to be referring to a particular animal.

Thank you.

You’re welcome!

Yes, the subjects in all three sentences are used in a generic sense. In sentence 1, "A clever animal" is a generic reference to any clever animal that is used by people. In sentence 2, "The clever animal" implies that there is a specific clever animal being referred to, but it is still used in a general sense to represent any clever animal. In sentence 3, "Clever animals" is a plural form, indicating that multiple clever animals are being referred to in a generic manner.
