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 from 29 to 36. “Family” includes your siblings and parents, as well as relatives who you may not interact with every day, such as your cousins, aunts, aucles, grandparents, and stepparents. These are probably the people you are closest to and with whom you spend the most time. Having healthy relationships with your family members is both important and difficult. Families in the 21st century come in all shapes and sizes: traditional, single parent, blended (more than one family together in the same house), and gay and lesbian parents - just to mane a few. No matter the “type” of family you have, there are going to be highs and lows - good times and bad. Many times, however, families become blocked in their relationships by hurt, anger, mistrust, and confusion. These emotions are natural and normal, and few families do not have at least a few experiences with them. The worst time for most families, is during a divorce. By making a few simple changes in the way we look at the world and deal with other people, it is possible to creat happier, more stable relationships. Families need to be units of mutual caring and support; they can be sources of lifelong strength for all individuals. Thus, it is never too late to begin the process of improving family relationships - even if they are already of good quality - by developing some simple skills. Whereas in other situations you can step back and assess the relationship, it is oftenhard to do this with your family. Your family may be a constant presence in your life, so when an argument or issue arises, it may seem impossible to handle. However, remember that communication is key to resolving conflict. While it may seem that your siblings are constantly present to annoy you or boss you around , they are also there there to communicate. Thus, use your family’s presence to your advantage - communicate with each other, develop ways to value boundaries, and build trust and respect. Question 1.
