The mirror question

Test takers report a question involving whether the reflective qualities of a mirror

should be included in the specification. You were to choose from a list of choices

that comported with USPTO practice and procedure. Among the answers (from memory):

(A) Because the definition of mirror automatically includes its reflective qualities,

there is no need to amend the specification to include the reflective qualities

(E) The mirror in one part of the specification is “parallel”, and the mirror in another

part is “perpendicular”. The specification is conflicting and one who has knowledge in

the art would not be able to tell the difference, so amend the specification.

I picked (E) which talked about perpendicular and parallel mirrors and 112 indefinite,

as opposed to (A) and (B) which talked about inherent qualities and the definition of "mirror".
