Question

complete the sentence with the word that best fits the overall meaning and tone. the quality of the network drama ______ after the writers introduced too many competing story lines. mellowed deteriorated corroded

Explanation:

"Mellowed" means to become softer or milder, which doesn't fit the context of the drama quality worsening. "Corroded" is usually used for physical substances being eaten away, not for the quality of a drama. "Deteriorated" means to become worse, which is appropriate as the introduction of too - many competing story lines would likely make the drama quality decline.

Answer:

deteriorated
