Please have a look at these sentences
what I am interested in knowing is that how can a sentence be consider a GENERIC sentence. I have three different examples each have three sentences. Please have a look at my comments and let me know if I am on right track or not and also tell me the reason if I am wrong and the rule of its being acceptalbe or not.

A whale is an endangered species.@a. it is generic because it referes to all the whales @b. it can't be generic because it is talking about a specific whale so it can't be generalized@c. again it can't be generic as it is talking about one whale2@ a. Zebras have striped coats b. the Zebra has a striped coat c. A Zebra has a striped coat.@a. It is acceptalbe generic sentence because it referes to all zebras.

3@ a. Liquids have no shape b. a liquid has no shape c. the liquid has no shape.
@a. possible generic sentence as it is saying all liquids have no shape@b. not possible generic as liquid is uncountable so article a cannot be use and also even if article a is acceptable but it still couldnt be generic since it is refering to one liquid not generalizing.@c. cannot be generic as it is specifying the liquid so cant be generalized.
