On the other hand, girls prefer to host and attend pretend tea parties. But why do these differences W exist? Advanced Several months after babies are born, female babies like to look at a person's face to read emotions while male infants prefer to look at objects. Few would disagree that men care more about objects while women tend to empathize with others. However, the sex of our brain is not always as clear-cut as the sex of our body. In one experiment, a tough man, who seemed very competitive, was shown to possess a high degree of empathy, while a woman scored the highest in a hand- 10 eye coordination test at which men were thought to do better. This shows that the distinctions that set us apart might not be as clear as we think. 5 I t ZAN Differences between the sexes are hard to understand and so are relationships.

Problem 5: SE & IE A college student has two options for meals: eating at the dining hall (D) for $6 per meal, or eating a bread (B) for $1.50 per meal. Her budget is $60. 1. Draw the budget constraint showing the trade-off between dining hall meals and bread. Assuming that she spends equal amounts of expenditure on both goods as her optimum choice. What is this optimal choice (D,B)? Label the optimum as point A. 2. Suppose the price of a bread now rises to $2. Using your diagram from part (1), show how the change in price affect the budget line. Assume that the student now spends only 30 percent of her income on dining hall meals as her optimal choice. What is this optimal choice (D',B')? Label the new optimum as point B. 3. Use points A and B to draw a demand curve for bread. 4. Please write down the definitions of inferior good and normal good. For the student, is bread a normal good or an inferior good? Please explain. (Hint: Changes in consumption caused by this price change can be decomposed into substitution effect and income effect.)
