Read the passage, then choose the correct answers. 
No one knows the limits of population that the earth can support. Thomas Malthus, an English economist, developed a theory that became widely accepted in the nineteenth century. He suggested that because world population tended to increase more rapidly than the food supply, a continual strain was exerted upon available resources. Malthus cited wars, famines, epidemics, and other diseases as the usual limitations of population growth.
With recent advances in science and technology, including improved agricultural methods and great strides in medicine, some of the limiting factors in population growth have been lessened, with obvious results.
International organizations have put forward several recommendations to alleviate the problem of overpopulation, including an increase in food production, general economic development in target areas, and a decrease in birth rate. Most experts agree that it will be necessary to combine all three recommendations in an effort to affect a lasting solution.
Which of the following was not mentioned as the usual limitations of population growth?
A.A. wars                        
B.B. epidemics                           
C.C. famines                  
D. D. agricultural methods

Read  the  following  passage  and  mark  the  letter A, B, C, or D on  your  answer  sheet  to  indicate  the correct   answer  to  each  of  the  questions.
FAMILY LIFE IN THE UNITED STATES
              Family life in the United States is changing.  Fifty or sixty years ago, the wife was called a “housewife”.  She cleaned, cooked, and cared for the children.  The husband earned the money for the family.  He was usually out working all day.  He came home tired in the evening, so he did not do much housework.  And he did not see the children very much, except on weekends. 
              These days, however, more and more women work outside the home.  They cannot stay with the children all day.  They, too, come home tired in the evening.  They do not want to spend the evening cooking dinner and cleaning up.  They do not have time to clean the house and do the laundry.  So who is going to do the housework now?  Who is going to take care of the children?
              Many families solve the problem of housework by sharing it.  In these families, the husband and wife agree to do different jobs around the house, or they take turns doing each job.  For example, the husband always cooks dinner and the wife always does the laundry.  Or the wife cooks dinner on some nights and the husband cooks dinner on other nights.
              Then there is the question of the children.  In the past, many families got help with child care from grandparents.  Now families usually do not live near their relatives.  The grandparents are often too far away to help in a regular way.  More often, parents have to pay for child care help.  The help may be a babysitter or a day-care center.  The problem with this kind of help is the high cost.  It is possible only for couples with jobs that pay well.
              Parents may get another kind of help form the companies they work for. Many companies now let people with children work part-time. That way, parents can spend more time with their children. Some husbands may even stop working for a while to stay with the children. For these men there is a new word: they are called “househusbands”.  In the USA more and more men are becoming househusbands every year.
              These changes in the home mean changes in the family.  Fathers can learn to understand their children better, and the children can get to know their fathers better.  Husbands and wives may also find changes in their marriage.  They, too, may have a better understanding of each other.
The changes in the American home mentioned in this passage may ___________
A.help families     
B.not change the children at all
C.not happen       
D.cause problems for a marriage
