Sure-so this is a strengthen except so let's take a look--

A-strengthens because it provides direct evidence plant life pre dates half a billion years ago

B-strengthens argument by weakening claim life could have begun in oceans

C-strengthens by eliminating possibility that life producing organisms on the rock came from the ocean

E-mildly useful strengthener that the dating of the rocks was accurate.
