Industrial pollution has done seriously and possibly irreversible damage to the bronze horses on the facade of the cathedral of St. Mark La Venica.
(A) has done seriously and possibly irreversible damage to
(B) did damage that is seriously and possibly irreversible to
(C) damaged, serious and possibly irreversibly
(D) has done serious and possibly irreversible damage to
(E) did damage, serious and possibly irreversible
Correct answer: D
A: Not parallel/wrong adverb modifier "seriously" to modify noun "damage" (should be written "serious ... and possibly irreversible damage")
B: Wordy/awkward. Verb form (simple past vs. present perfect). "Seriously" should be the adjective "serious" as it modifies "damage."
C: Verb form as in B. "Serious" here should be an adverb ("seriously") because it modifies "damage." The clause "serious and possibly irreversibly" should end with a comma as it is separated off from the rest of the sentence.
D: Correct
E: "Serious and possibly irreversible" should be written as an adverb ("seriously and possibly irreversibly") and end with a comma.
