<span>Which one of the following actions should become an important part of your study schedule? </span><span>B. Eliminating the activity in which you spend the most time is your answer.
The reasoning behind this answer is because, </span>A. Finding out what works for others and then following the exact same schedule, isn't necessarily going to be most helpful for you. You can most definitely ask others what they do, and try new ideas, but you want whats best for you. And <span>C. Taking regular breaks from your studies to keep focused, isn't exactly good either. Taking a break here and there is okay. But only to an extent. You want to stay focused and sometimes taking a break can lead to distraction. Lastly, </span>D. Studying only in large blocks of time at one sitting, is obviously not correct. Cramming all at once is not very effective and can be stressful for some people. So B. Eliminating the activity in which you spend the most time is most helpful and effective. Eliminating the activity in which you spend the most time, such as on the internet or using electronics can reduce the amount of distractions greatly and therefore result in better practiced study habits.
