Answer:
I sincerely hope this helps but I can't do the work for you cause that won't help you understand.
Step-by-step explanation:
The mood of a verb refers to the manner in which the verb is expressed. Most verbs are indicative and are used to express statements of fact or opinion. ... A shift in the verb mood occurs when more than one mood is used in the same sentence. Unnecessary shifts should be avoided.
To fix this, we would rewrite the sentence to say, 'When Jim turned on the microwave, he heard a crackling sound. ' Now both verbs are in active voice and the sentence is written clearly. It is generally preferable to use the active voice over the passive voice.
