Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks from 23 to 27.

People come to this small country for many reasons. They can admire spectacular (23)_________ meet friendly natives, and enjoy a vibrant arts scene. Some are searching for their family (24) _________ or others just want to get away from it all and, digging up old memories from their English Lit class of gallant heroes engaging in larger-than-life struggles, their minds wander to faraway lands, to somehow familiar yet different destinations. Why not go to Scotland? But what kind of country are they coming to and what should they expect once they get there? Scotland (25) _________ of an area of 30, 418 square miles - so it's a fairly compact and "doable" country - with a population of about five million people - not too small, not too big. It is one of three countries that form the political (26) _________ called Great Britain, the other two being, of course, England and Wales, which, along with their fourth partner, Northern Ireland, becomes the United Kingdom. Scotland is bordered on three sides by water and on its fourth by England, which has had both its advantages and disadvantages. Geographically speaking, the country can be divided into three broad areas, the Southern Uplands, the Central Lowlands, and the Highlands. Although the rugged Highlands (27) _________ about two-thirds of the land area, the vast majority of the population lives in the Central Belt between Glasgow, Scotlands largest city, and Edinburgh, Scotland's capital.

Read the following passage about the impact of social media on mental health 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] In recent years, social media platforms have become a central part of daily life, offering users countless ways to connect, share, and communicate. [II] While these platforms offer many advantages, experts have noted rising concerns about their effects on mental health, particularly among young people (Smith & Anderson, 2018). [III] Studies reveal that excessive social media use can contribute to feelings of anxiety, depression, and loneliness, despite its intention to promote connection and social interaction (Twenge & Campbell, 2019). [IV]

          A primary reason for these mental health concerns is the tendency for social media users to compare themselves to others. Platforms like Instagram and Facebook often highlight idealized lifestyles, leading users to feel inadequate about their own lives. Additionally, the constant notifications and messages contribute to a "fear of missing out," or FOMO, which keeps individuals in a cycle of checking their phones, often reducing the quality of sleep and overall well-being.

          There is also a growing body of research suggesting a link between social media use and decreased attention spans. When users frequently switch between apps and notifications, their ability to focus for extended periods may diminish (Rosen, 2019). This shift in attention can interfere with productivity, especially in academic and professional settings, where sustained focus is essential.

          Addressing these challenges requires a multi-faceted approach. Some mental health professionals suggest limiting screen time and setting boundaries, such as "device-free" hours before bedtime. Others recommend engaging in offline activities, like reading or exercising, to reduce dependence on social media and build healthier habits. According to psychologists, such strategies can enhance mental resilience and allow for more meaningful, balanced relationships (Robinson & Smith, 2020).

Foot-racing is a popular activity in the United States. It is seen not only as a competitive sport but also  as  a  way  to  exercise,  to  enjoy  the camaraderie  of  like-minded  people,  and  to  donate  money  to  a good  cause.  Though  serious  runners  may  spend  months  training  to  compete,  other  runners  and  walkers might not train at all. Those not competing to win might run in an effort to beat their own time or simply to enjoy the fun and exercise. People of all ages, from those of less than one year (who may be pushed in strollers)  to  those  in  their  eighties,  enter  into  this  sport.  The  races  are  held  on  city  streets,  on  college campuses, through parks, and in suburban areas, and they are commonly 5 to 10 kilometers in length.
The  largest  footrace  in  the  world  is  the  12-kilometer  Bay  to  Breakers  race  that  is  held  in  San Francisco every spring. This race begins on the east side of the city near San Francisco Bay and ends on the west side at the Pacific Ocean. There may be 80,000 or more people running in this race through the streets and hills of San Francisco. In the front are the serious runners who compete to win and who might finish  in  as  little  as  34  minutes.  Behind  them  are  the  thousands  who  take  several  hours  to  finish.  In  the back of the race are those who dress in costumes and come just for fun. One year there was a group of men who dressed like Elvis Presley, and another group consisted of firefighters who were tied together in a  long  line  and  who  were  carrying  a  fire-hose.  There  was  even  a  bridal  party,  in  which  the  bride  was dressed  in  a  long  white  gown  and  the  groom  wore  a  tuxedo.  The  bride  and  groom  threw  flowers  to bystanders, and they were actually married at some point along the route.

The main purpose of this passage is to _________.
