The sentence is intended to say that, although
heirloom tomatoes may appear to be less
appetizing than the round, red supermarket
variety, the often green and striped or bumpy
and bruised heirloom tomatoes actually are more
flavorful. Any version of the sentence in which
green and striped, have bumps and bruises, or are
more flavorful appear to modify round and red
supermarket cousins is ill-formed.
A) In this version of the sentence, often green
and striped, have plenty of bumps and bruises,
and are more flavorful all illogically appear
to modify round and red supermarket cousins
rather than heirloom tomatoes.
B) In this version of the sentence as well,
often green and striped, with plenty of bumps
and bruises, and although more flavorful all
illogically appear to modify round and red
supermarket cousins rather than heirloom
tomatoes.
C) In this version of the sentence, often green
and striped illogically appears to modify
round and red supermarket cousins rather than
heirloom tomatoes.
D) Although in this version green and striped
and with plenty of bumps and bruises clearly,
and correctly, modify heirloom tomatoes, the
or in they are often green and striped, or with
plenty of bumps and bruises is unnecessary
and awkward. Furthermore, the final clause
is ungrammatical and should say although
they are more flavorful.
E) Correct. In this version of the sentence,
green and striped, with plenty of bumps and
bruises, and are more flavorful clearly, and
correctly, modify heirloom tomatoes, and the
phrases in the sentence are appropriately
parallel with one another.
