Although early soap operas were first aired on evening radio in the 1920's, they had moved to the daytime hours of the 1930's when the evening schedule became crowded with comedians and variety shows. 



(A) were first aired on evening radio in the 1920's, they had moved to the daytime hours of the 1930's 


(B) were first aired on evening radio in the 1920's, they were moved to the daytime hours in the 1930's 


(C) were aired first on evening radio in the 1920's, moving to the daytime hours in the 1930's 


(D) were aired first in the evening on 1920's radio, they moved to the daytime hours of the 1930's 


(E) aired on evening radio first in the 1920's, they were moved to the 1930's in the daytime hours


This question is based on Tense and Construction.


The sentence gives us information about soap operas in two decades – the 1920’s and the 1930’s. The two pieces of information must be conveyed in verb forms that are consistent with each other. 


In Option A, the verb forms are not consistent. The verb “were aired” is in the simple past tense in the passive voice, but the verb “had moved” is in the past perfect tense in the active voice. The active voice implies that the soap operas chose to move to the daytime hours; since this meaning is illogical, Option A can be eliminated.


Option C is incomplete. It is made up of a subordinate clause - Although early soap operas were first aired on evening radio in the 1920's – and a participle clause - moving to the daytime hours in the 1930's when the evening schedule became crowded with comedians and variety shows. So, Option C can also be eliminated.


Option D repeats the error in Option A. The first part of the sentence is in the passive voice and the second part of the sentence is in the active voice. The verb in the simple past tense “moved” conveys the idea that the soap operas chose to move to the daytime hours. So, Option D can also be eliminated.


Option E contains the same error as Options A and D, but in the reverse. In this option, the verb “aired” is in the active voice, implying that the soap operas did the action. So, Option E can also be eliminated.


In Option B, the verbs – were aired and were moved - are in the passive voice and are parallel, conveying the intended meaning that they were aired and were moved by the people in charge. Therefore, B is the most appropriate option.
