Final answer:
The sentence should be completed as 'The petulant argument that raged in the office for days was not conducive to getting work done,' where 'petulant' describes the nature of the argument and 'conducive' relates to the hindered productivity.
The correct answer is D. Protracted; conducive.
Step-by-step explanation:
The correct answer to the sentence completion is: 'The petulant argument that raged in the office for days was not conducive to getting work done.' Here, 'petulant' means childishly sulky or bad-tempered, which fits into the context of an argument that would disrupt an office environment.
'Conducive' means making a certain situation or outcome likely or possible; hence, a petulant argument is not conducive to productivity.
The correct answer is D. Protracted; conducive.
The word protracted means lasting for a long time or longer than expected. In this context, it means that the argument lasted for days.
The word conducive means making a certain situation or outcome likely or possible. In this context, it means that the argument wasn't helpful or productive in getting work done.
