Artists have different ways of producing contours and
hatching, and analysis of these stylistic features can
help to distinguish works by a famous artist both from
forgeries and from works genuinely by other artists.
Indeed, this analysis has shown that many of the
drawings formerly attributed to Michelangelo are
actually by the artist Giulio Clovio, Michelangelo's
contemporary.
If the statements above are true, then which one of the
following must also be true?
(A) Contours and hatching are the main features that
distinguish the drawing styles of different
artists.
(B) Many of the drawings formerly attributed to
Michelangelo are actually forgeries.
(C) No forgery can perfectly duplicate the contour
and hatching styles of a famous artist.
(D) The contour and hatching styles used to identify
the drawings of Clovio cited can be shown to
be features of all Clovio's works.
(E) There is an analyzable difference between
Clovio's contour and hatching styles and those
of Michelangelo.
