During the 1970s, the demand for long-lasting staple foods
prompted the adding of preservatives to dishes that previously were simple, whereby the quality of their flavors was reduced.(A) prompted the adding of preservatives to dishes that previously were simple, whereby the quality of their flavors was reduced
(B) prompted the addition of preservatives to previously simple dishes, so the quality of their flavors were reduced
(C) prompted them to add preservatives to previously simple dishes, reducing the food's flavor quality
(D) prompted the addition of preservatives to previously simple dishes, a change that reduced the quality of the food's flavors
(E) prompted the addition of preservatives to previously simple dishes, which reduced the quality of the food's flavors
Meaning analysis: In the past (1970) some demand suggested to add some preservatives to food, thus quality of the food's flavors reduced.
Error analysis: Modifier placement, that modifies dishes, but per the meaning of the sentence it has to modify preservatives. Pronoun ambiguity, plural “their” can refer both “dishes” and “preservatives”. Idiom add
X to
Y, addition of
X to
Y.
(A) prompted the adding of preservatives to dishes
that previously were simple, whereby the quality of
their flavors was reduced
(B) prompted the addition of preservatives to previously simple dishes, so the quality of
their flavors
were reduced
(pronoun ambiguity, singular “quality” cannot take plural “were”)(C) prompted
them to add preservatives to previously simple dishes, reducing the food's flavor quality
(“them” has no clear antecedent, reducing correctly modifies preceding clause)(D)
prompted the addition of preservatives to previously simple dishes, a change that reduced the quality of the food's flavors (here noun+noun modifier correctly modifies preceding clause, noun – “a change”, noun modifier – “that reduced the quality of the food's flavors”, no other errors)(E) prompted the addition of preservatives to previously simple dishes,
which reduced the quality of the food's flavors
(which cannot modify clauses)IMO answer choice
D is correct.
(please correct if I'm mistaken, thank you)
