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.

When parents name their children, they often take into consideration their own preferences, family traditions, or beliefs. In many European cultures, parents typically select names based on family connections, often honoring grandparents or ancestors. For instance, in Italy, children are commonly named after their grandparents, starting with the father's parents and then the mother's. Similarly, in Eastern Europe, children may be named after their deceased relatives to protect them from harm.

In some Asian countries, the naming process may involve the child's grandfather or a fortune-teller, who chooses a name believed to shape the child's character. Names might be inspired by elements like fire, water, earth, wood, or metal, or they may convey qualities such as beauty, strength, or kindness.

African cultures also have unique naming traditions, such as in Ghana's Akan culture, where a child's name is determined by the day of their birth. Each day has specific names for boys and girls, reflecting characteristics associated with that day. For example, a boy born on Friday might be named Kofi, symbolizing a "wanderer" or "explorer" while a girl born on the same day could be named Afua, also representing a traveler.

No matter where a name originates, it holds significant meaning and reflects the child's cultural heritage. Whether chosen out of preference or dictated by tradition, a child's name is a cherished and respected gift.

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.

Where in paragraph I does the following sentence best fit?
"Cultural differences in behavior can lead to unintended offense in certain regions."
