Which would you choose: A stressful job with very high pay or a relaxing job with considerably low p

Hi [이름]! Thank you for completing your homework today. It was a refreshing read. I have the same preference as you have. You did a good job in the presentation of your work. You also used good grammar in all your sentences. You just need to be more careful with your spelling and some verb tenses. You should use past tense if the event you are talking about happened in the past. You may have just overlooked them because I can tell that you truly have a superb writing skill. Great work! I like to see more of your work in the future :)~~T. Dee
