Read the following passage about gender equality 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.
GENDER EQUALITY TODAY
Gender equality is a fundamental human right and a critical foundation for a peaceful, prosperous, and sustainable world. [I] Despite significant progress in recent years, gender inequality remains a pressing issue across the globe. [II] Women continue to be underrepresented in leadership positions and face numerous barriers in various sectors, including education, healthcare, and the workforce. [III] According to the World Economic Forum’s Global Gender Gap Report 2021, it will take an estimated 135.6 years to close the gender gap globally if current trends continue. [IV]
In many countries, women are still subjected to discrimination and violence. Gender-based violence, including domestic violence and sexual harassment, affects millions of women worldwide and hinders their ability to participate fully in society. Additionally, cultural and societal norms often perpetuate stereotypes that limit women’s roles and opportunities.
However, there are positive signs of change. Movements advocating for gender equality have gained momentum, and more individuals are recognizing the importance of women’s rights. Governments and organizations are implementing policies to promote equal opportunities and protect against discrimination. Education plays a vital role in this transformation, as empowering girls through education can lead to improved economic outcomes and healthier communities.
Achieving gender equality is not only a matter of fairness; it is essential for the advancement of society as a whole. By ensuring equal rights and opportunities for all genders, we can create a more just and equitable world.
(Adapted from United Nations. “Gender Equality.” UN Women. 2021)

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.
Who are you?
On 6 June 2011, the media reported the kidnapping of a female Syrian-American blogger called Amina Arraf. Regarded as a daring political rebel, the 35-year-old had gained popularity for her blogs protesting the lack of freedom in Syria. Yet, only two days later, it was discovered that Amina had never existed. She was a fictional character created by Tom MacMaster, a forty-year-old American PhD student at the University of Edinburgh.
MacMaster's invention is an example of sock puppetry: the use of false identities to deceive others. (I). The false identity is known as a sock puppet, and its creator, a puppet master. (II). MacMaster created Amina to express his views on Middle Eastern affairs without offending other Americans. (III). Writing as Amina gave him the authority to say what he wanted. (IV).
At the turn of the millennium, Debbie Swenson created Kaycee Nicole, a fictional teenage girl suffering from terminal cancer. Her blog, Living Colours, described Kaycee’s struggle, attracting millions of readers. When Kaycee 'died' on 14 May 2001, her fans were devastated. Their distress turned to anger when they discovered that Kaycee was not real. Swenson had developed the character to gain attention and sympathy.
While Amina and Kaycee were used to meet their creators' needs, other identities have been invented for profit. American gun advocate John Lott made up a fake student, Mary Rosh, to defend his writing online and give him positive reviews. Mystery writer RJ Ellory fabricated a team of sock puppets to praise his own books and tear into those of his rivals. British historian Orlando Figes lost credibility when he had to publicly apologise for doing the same.
Yet none of these stories compare to large-scale sock puppetry today. The New York City Police Department has false identities on social media to catch criminals. The US military is believed to use sock puppets to track potential terrorists. It is clear that the internet is a minefield today and we all have to step very carefully in order not to get hurt.
Which of the following best paraphrases the underlined sentence: "It is clear that the internet is a minefield today and we all have to step very carefully in order not to get hurt."

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.
Which of the following is TRUE according to the passage?
