问题 In reading mathematics problems, you should first read to understand the general meaning of the problem and question to be answered. At first you need not notice the exact figures given. Look at the following problem.
   James wants to buy a pair of roller skates that were priced at $6.50. One day he saw the price had been reduced to $5.25. He has $4.50. How much more money does he need to pay for the skates?
   The first reading of this problem might be as follows:
   James wants to buy a pair of roller skates that were priced at a certain amount. One day he saw that the price had fallen. How much more money does he need to pay for the skates?
   From the reading you can decide that you must subtract (减去) what James has from the cost of the skates to answer the question. Then look at the problem and get the exact figures. You will notice that you do not need to know the original price of the skates.
The proper title for this passage should be ______.
选项 A、How to Work Out Maths Problems
B、How to Get Exact Figures
C、How to Answer a Question
D、How to Read Maths Problems
