3．A．Therefore，what economists try to do is to persuade people to reduce missed opportunities to save the cost．
B．For every hour we work at one job we could quite easily be doing another，or be sleeping or watching a film．
C．The biggest restriction on our resources is the number of hours we can devote to something，so we look to maximize the return we get on our investment of time．
D．We should weigh the choices of opportunities，learning to give up for better ones and obtaining what we want besides profits．
AB．For economists，every decision is made by knowledge of what one must forgo-in terms of money and enjoyment-in order to take it up．
AC．Yet，in a sense it's human nature to do precisely that-we assess the advantages and disadvantages of decisions all the time．

However wealthy we may be，we can never find enough hours in the day to do everything we want．Economics deals with this problem through the concept of opportunity cost，which simply refers to whether someone's time or money could be better spent on something else．
Every hour of our time has a value．（92）BEach of these options has a different opportunity cost-namely，what they cost us in missed opportunities．
Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get to and from the stadium．Why not，you might reason，watch the game from home and use the leftover money and time to have dinner with friends？This-the alternative use of your cash and time-is the opportunity cost．
（93）AB．By knowing precisely what you are receiving and what you are missing out on，you ought to be able to make better-informed，more reasonable decisions．Consider that most famous economic rule of all：there's no such thing as a free lunch．Even if someone offers to take you out to lunch for free，the time you will spend in the restaurant still costs you something in terms of forgone opportunities．
Some people find the idea of opportunity cost extremely discouraging：imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable．（94）AC．
In the business world，a popular phrase is"value for money．"People want their cash to go as far as possible．However，another is fast obtaining an advantage："value for time．"（95）C．By reading this passage you are giving over a bit of your time which could be spent doing other activities，such as sleeping and eating．In return，however，this passage will help you to think like an economist，closely considering the opportunity cost of each of your decisions．
