Read the following passage about the impact of tweeting on everybody and mark the letter A, B, C or D on your answer sheet to indicate the option that best fits each of the numbered blanks from 18 to 22

EVERYBODY’S TWEETING

Twitter (18) ________________ for a podcasting website, but then people realized that it offered them the power to connect with millions of people instantly. Suddenly, everyone had a voice, as long as it wasn’t longer than 140 characters. But what are we using it for, and just how is Twitter changing the way we do things?

Perhaps the greatest impact Twitter has had is on breaking news. Before Twitter, (19) _____________ before finally broadcasting it on the radio or TV. These days, anyone who happens to be in the right place at the right time with a Twitter account can post news the second it happens. For example, Janis Krums posted a photo and a tweet when he witnessed a US flight making an emergency landing in the Hudson River. He must never have imagined that he would break the story to the world.

Following Pop Idols

Young people have always loved to follow their pop idols, and Twitter has made it a whole lot easier. Before the Internet, teenagers used to join the fan clubs of their favorite bands and write letters to their heroes,

(20) _________________ to get a reply written by the club secretary. Today’s teenagers don’t need to wait. By following their idols on Twitter, they get all the news the minute it happens: their meals, activities, or even thoughts. And all the news comes directly from the bands themselves.

It’s good to get an idea of the background of a person who says or writes something. Are they an impartial expert or someone who wants to change your opinion to suit their own agenda?

On the other hand, “We have to stop people who are carrying the virus from getting into the country” is more likely to come from a politician. (22) _____________, you’re better able to decide how much importance to give it and whether you can really trust what they say.

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

URBANISATION: A GROWING PHENOMENON

     Urbanisation is the process through which cities grow, and higher populations begin to inhabit urban areas. This phenomenon has accelerated significantly over the past few decades due to various factors. One of the primary drivers is the search for better employment opportunities. In rural areas, job prospects are often limited to agriculture and small-scale industries, which might not provide sufficient income. Consequently, people migrate to cities seeking better livelihoods and living standards.

     Additionally, urban areas offer more advanced educational facilities and healthcare services compared to rural regions. Many families move to cities to provide their children with higher-quality education and greater future opportunities. Access to hospitals and specialized medical services also attracts people to urban centers, especially in countries where rural healthcare is underdeveloped.

     However, rapid urbanisation brings about several challenges. Overcrowding in cities can lead to inadequate housing, strained infrastructure, and increased pollution. The expansion of urban areas often results in the loss of green spaces and agricultural land, impacting food production and the environment. Governments and city planners must address these issues to ensure sustainable urban growth.

     Despite these challenges, urbanisation has several positive aspects. Cities are often cultural melting pots, where diverse groups of people interact, leading to vibrant communities and innovation. The concentration of resources and talents in urban areas can drive economic growth and technological advancements.

The word This phenomenon in paragraph 1 refers to ____.

Read the following passage about the Koromi trend 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]. If you’ve done any traveling at all, you’re likely quite aware that customs and etiquette differ from one culture to another: what may be perfectly innocuous in one place may be hideously offensive in another, and vice-versa. [II]. Granted, even if you haven’t traveled at all, you’re probably aware of the fact that certain types of behavior aren’t exactly acceptable in other countries: belching at the table may be a sign of gratitude in some places, but in most areas of North America and Europe, such a display will earn you a fair bit of ire. [III]. Whether you plan on traveling to any of the places listed below or just doing business with a foreign client, it’s important to educate yourself on the standards of politesse and etiquette beforehand-the last thing you want to do is offend someone with any ignorant, boorish behavior. [IV]. Here’s how to be polite in different countries.

When dealing with Japanese clients, be sure to dress fairly conservatively, and make sure that you bow lower than they do upon meeting them. Accept gifts with both hands and open them later, not in front of the giver, and never blow your nose at the dining table. Avoid asking and answering direct questions: it’s better to imply rather than ask, and to answer with vagueness during conversations.

In Kenya, when greeting someone older or of a higher status than yourself, grip their right wrist with your left hand while shaking it; it’s a sign of respect and deference. Do ask questions about their health, family, business etc. before getting to major topics, as skipping these niceties is seen as impolite. If sharing meals, do not begin eating until the eldest male has been served and starts to eat.

Turning down an alcoholic drink is considered terribly offensive in Russia, so it’s a good idea to fortify yourself with some greasy food before heading out for a meal with Russian or Ukrainian clients. Don’t smile at strangers or they’ll think you’re deranged, and when paying for items, place your money on the counter rather than trying to hand it directly to the cashier.
