Official Solution:Taking note of the success of local farmers’ markets, the university’s food service providers have transitioned into a locally-grown, sustainable operation.A. have transitioned into a locally-grown, sustainable operation
B. have transitioned into sustainable, locally-grown operation
C. have transitioned into locally-grown, sustainable operations
D. are transitioned into sustainable, locally-grown operations
E. are transitioning into locally-grown, sustainable operation
This question tests correct agreement between the plural food service providers and the word operation, which should also be the plural operations. The words are divided by an intervening phrase, but they must still agree. Also tested is the use of the verb form have transitioned to indicate that a change has already occurred.
- The word a and the singular operation do not agree with the plural food service providers.
- Operation must become the plural operations; also, placing sustainable before locally-grown is unnecessary and does not change either the structure or the content of the sentence.
- The plural operations agrees with food service providers and no unnecessary word order changes have been made.
- The verb form are transitioned does not make sense in the sentence; also, the placement of sustainable before locally-grown is unnecessary.
- Operation is singular and does not agree with food service providers. Also, nothing in the sentence indicates that the present progressive are transitioning is needed.
