|I think they did not provide the correct answer: Only I and IV follow.|

|The logic only flows one direction through these sentences.
For example, it tells us that all pencils are birds, but it does not tell us that all birds are pencils. It tells us all birds are skies, but it does not tell us that all skies are birds. And. It tells us that all skies are hills, but it does not tell us that all the hills are skies.
Therefore you can say that any logic flowing the one direction is a correct answer while any logic flowing the other direction is not.

|Considering the premises "All pencils are birds, all birds are skies''.
The conclusion will be All pencils are skies. But All skies are pencils (conclusion III) IS THE CONVERSE of the conclusion. If conclusion III is not included it makes the explanation delusional.

|By venn diagram, I and IV are valid. If all birds are hills vide skies, "all hills are birds" is not valid. "Only some Hills are birds" is valid. Similarly if " all pencils are skies" is valid vide birds, only "some skies are pencils" is valid. All skies are pencils is not valid.|
