Read the following passage about the CULTURAL DIVERSITY and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

[I] Belgium features a fascinating mix of ancient traditions and contemporary legislation, showcasing the country’s rich history. [II]. In Belgium, the families of the bride and groom each pitch in by providing a sheet of paper for the wedding invitations, in line with a long-standing tradition. [III] The wedding invitations symbolize the new partnership and the merging of the two families. [IV]

In an old Belgian tradition meant to bring the two families closer together, the bride would pause halfway down the aisle to give her mother a solitary flower. They hold each other's arms. The newlyweds then make their way to the groom's mother-in-law during the recessional, where the bride presents her with a solitary flower as a token of her affection. As a sign of the bride's acceptance of her new mother, they embrace.

Carrying a uniquely embroidered handkerchief bearing the bride's name is one of the most significant and long-standing customs of the Belgian wedding. This handkerchief will be framed and displayed in a special spot after the wedding. Before each subsequent female member of the bride's family is married, the handkerchief is taken out of its frame, embroidered with the name of the new bride, and then passed down through the generations. A bridal handkerchief is a treasured memento that is passed down through the generations.

There are two big chairs placed near the altar where the bride and groom sit during the wedding mass, representing their throne as king and queen for the day and the location. As the ceremony comes to a close, the groom places the wedding ring on the third finger of the bride's left hand. Because it is a circle, the ring represents love that knows no bounds, and the third finger of the left hand represents love because it is thought to hold the vein that goes to the heart. Soon after the wedding, the newlyweds kiss for the first time as husband and wife. Because each partner takes a breath of their new spouse's spirit, the kiss is a metaphor for the couple's spiritual union.

Traditionally, as the bride and husband leave the church, the bridesmaids gather a handful of pennies and then scatter them among the less fortunate outside. The happy couple might increase their chances of financial success by donating to charity.

A honeymoon is for the newlyweds after the wedding. Honey wine, or mead, was traditionally drunk during the 28-day honeymoon, which corresponds to one lunar cycle, in ancient times. The purpose of this was to prevent the bride's relatives from attempting to reclaim their daughter from her husband.

The word “they” in paragraph 2 refers to____________.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

Working on Your Workout

(I) Although appreciating a balanced diet and regular exercise, most people do not know how to exercise properly. Consequently, they usually rush through their workouts, or they make the same common workout mistakes. (II) Exercising the right way is important for people who are worried about their health and their appearance. (III) However, if someone is not working out properly, they will not see the results they want. Therefore, training experts have devised tips to teach people how to exercise correctly in order to achieve the greatest health benefits. (VI)

One of the most common workout mistakes is doing the same routine over and over again. This does not challenge your muscles, and it can actually prevent muscles from growing and repairing themselves. Instead of always sticking to the same old workout, it is important to change your routine every six to eight weeks. It is also important to add a variety of workouts to your routine, such as swimming, yoga, or biking, to make sure your whole body stays fit. This will help make your workouts more interesting, and benefit your health and muscle development as well.

Another mistake people tend to make is to work out too hard, too often. Your body needs to rest between workouts; otherwise, no progress will be made. It is best to keep the number of hard workout routines to no more than two per week. Then, for those who don’t want to get off schedule by skipping a day, shorter workouts of about twenty minutes can be used on other days. For more variety in workouts, you could also plan an easier routine for forty to sixty minutes between days of shorter, more intense workouts. Experts recommend, however, taking at least one day off completely each week, especially after several hard workout days in a row.

In reality, no one is perfect. However, if you want to make a difference in your overall health, there are some things you can do. Stretch before and after every workout. Do not rush your routine, and do not work out too little or too much. Remember not to make these common workout mistakes, and always have fun while exercising!
