Answer:
<em>We tend to weigh our alternatives, so as to achieve our goal over a specific time, such as time created to study or for leisure</em>
Explanation:
<em>Human wants are endless. resources on it's own are scarce.</em>
<em>The basic problem of economics, is the deals with the allocation of resources systematically so that the result of the output can fully be managed maximally for the betterment of a nation.</em>
<em>Now, to choose between different options, the cost and related benefit needs to be understood.</em>
<em>The cost for taking a decision involves what we may give up by not having an alternative choice. while the best method or choice we give up when we make a decision is called the decision opportunity cost.</em>
<em>One of the problems that limit our resources, that constraints our behavior is time.</em>
<em>We only have 24 hours a day in order to reach our objective or aim, so we have to make use of the time very well, thus we tend to weigh in our alternatives and provide a specific time for our day to day activities.</em>
<em>An individual can devote his or her time in both leisure and study, different alternatives for individual may include part time job, library work. also same applies for study.</em>
