I’ll try to help my best “ a troubled mind caused me to walk abroad” i think he means while his mind is troubled or he has a lot on his mind he is pacing as one would tend to do when stressed
What I would do is contact my superior and ask him/her what they would want me to . do. Whatever the superior says then I would have to obey so I don't get fired. If this happens on a daily bases at your job then I would start searching for another job. Once you have found another job that you might like then I would take that one and leave the other one. Or you could just tough it out and your superior will take notice and he/she might offer you a better position. Hopefully this helps.
The answer is B) it can motivate the events of a story.
I hope this helps :)
