Part II Reading Comprehension There is nothing similar in the way men and women shop for groceries. Believe me, I know, because I work in a major supermarket. After watching scores of people shop for food day in and day out, I have become somewhat of an expert on the habits of American consumers. I have noticed many things about them, but nothing stands out more clearly than the differences between men and women when they shop. First of all, men never know where anything is. Despite the recent trends in equality,which demands that a man should share the domestic chores, there are still more women shoppers in America’s grocery stores. And these women know what they’re doing. Women are exceptional food shoppers, who always know where something is. Nine times out of ten, it will be a man who asks an employee to find a product for him. I don’t know how many men shoppers come up to me during a night to ask me where something is, but 50% of those who invariably return to me in five minutes still unaware of the product’s location. Men have no sense of direction in a supermarket. Women, on the other hand, rarely ask for an item’s location. When they do, it is usually for some product that only they have ever heard of and whose name only they can pronounce. Another difference between men and women is that women shop at speeds that would get them tickets on freeways, while men shop with all the speed of a dead snail. A woman who’s really good can get her shopping done in the same amount of time every time she goes. A man who shops just as often will get worse and worse every time. The biggest difference between the sexes in regard to shopping, however, involves the manipulation of carts. A woman guides a cart through the store so effortlessly that her movements are almost poetic. Men are an entirely different story. They have no idea of how to control the direction of carts. To a man, a shopping cart is some sort of metal monster designed to embarrass him. Overall, women are far more proficient shoppers than men. Women are safe and graceful, while men are dangerous and clumsy. I know these things because I work in a supermarket. I also know these things because I am a man. Q1: Which of the following is one of the differences between men and women?
A.
Men are doing more housework than women are.
B.
Women always know where something is in grocery stores.
C.
There’re fewer male shoppers than female ones in the supermarket.
D.
Men are more curious than women are so that they like to ask questions.
