Marriage nowadays is a choice people make on their own, but this has not always been the case in society. Thousands of years ago, the average lifespan was shorter than it is today. A man usually lived until he was about 40 years old, while women died even sooner because of childbirth. There were many wars and illnesses, and people had to protect themselves by having more children while they were still young. The parents lived through their children.

          Marriage was not so much a romantic love story but a business transaction, or deal. Most marriages were arranged between parents while their children were still very young. It was the custom that the fathers made the decision on whom their children were going to marry. The mothers had little say in it since they rarely made any decisions outside the household. The fathers would meet to arrange the wedding date and the money given for the bride on her wedding date. The more money and land a girl had, the more chances she had to marry well. Therefore, it was important that her father choose the bridegroom very well. Usually, it was someone who came from a good family or who was rich too. It was very unlikely that people married outside their social class. A few well-off and rich merchants got to marry poorer noblewomen and became King’s business advisors. In a way, poor peasants had an easier choice as it was less important whom they married.

The practice of arranged marriage is still common in some countries in the Middle East, such as India or Pakistan. Here, social classes are still strongly divided and very well-kept. Often, however, arranged marriages are a sign that people do not want to let go of the past, which gives them comfort and security in an ever- changing world.

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 28 to 35.

Do you feel like your teenager is spending most of the day glued to a phone screen? You're not too far off. A new survey from the Pew Research Center reveals the surprising ways that technology intersects with teen friendships — and the results show that 57 percent of teens have made at least one new friend online. Even more surprisingly, only 20 percent of those digital friends ever meet in person.

While teens do connect with their friends face-to-face outside of school, they spend 55 percent of their day texting with friends, and only 25 percent of teens are spending actual time with their friends on a daily basis (outside of school hallways). These new forms of communication are key in maintaining friendships day-to-day — 27 percent of teens instant message their friends every day, 23 percent connect through social media every day, and 7 percent even video chat daily. Text messaging remains the main form of communication — almost half of survey respondents say it's their chosen method of communication with their closest friend.

While girls are more likely to text with their close friends, boys are meeting new friends (and maintaining friendships) in the gaming world-89 percent play with friends they know, and 54 percent play with online-only friends. Whether they're close with their teammates or not, online garners say that playing makes them feel "more connected" to friends they know, or garners they've never met.

When making new friends, social media has also become a major part of the teenage identity-62 percent of teens are quick to share their social media usernames when connecting with a new friend (although 80 percent still consider their phone number the best method of contact). Despite the negative consequences-21 percent of teenage users feel worse about their lives because of posts they see on social media — teens also have found support and connection through various platforms. In fact, 68 percent of teens received support during a challenging time in their lives via social media platforms.

Just as technology has become a gateway for new friendships, or a channel to stay connected with current friends, it can also make a friendship breakup more public. The study reveals that girls are more likely to block or unfriend former allies, and 68 percent of all teenage users report experiencing "drama among their friends on social media."

Question 35: What does the writer mean when saying "68 percent of all teenage users report experiencing "drama among their friends on social media"?

A. Most teenagers take part in drama on social media.

B. Most friends on social media of teens are reported in drama.

C. Most teenagers use their experience in drama with their friends on social media.

D. Most teenagers have ever had conflicts with friends on social media.
