This draws an inference from a “some” statement and a “none” statement. Some poems in this collection have a regular meter, but none of the poems written by Strawn do, which means that at least some of the poems in this collection could not have been written by Strawn.

Mismatched premises. This gives two “some” statements and draws a flawed conclusion. All (B) tells us about the collection is that it has some poems with a regular meter, but there’s still room in it for poems without a regular meter. So it’s still possible that all of Strawn’s poetry is in the collection.

Mismatched premises. This gives us disconnected “some” and “none” statements and draws a flawed conclusion. All (C) tells us about the collection is that it doesn’t have any of Strawn’s poetry—we have no idea whether it contains poems with regular meters or not.

Mismatched conclusion. From (D)’s premises, we could conclude that some of Strawn’s poetry does not have a regular meter, but we can’t make any distinction between Strawn’s published and unpublished poetry.

Mismatched premises. This gives us two disconnected “none” statements and draws a flawed conclusion. All (E) tells us about Strawn’s poetry is that none of it is in this collection—we have no idea whether any of it has a regular meter or not.
