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.

          Happiness is a universal goal, yet its ingredients differ across societies and cultures. For some, safety and security are paramount, as demonstrated by Singapore. Known for its strict laws and highly regulated environment, Singapore provides a clean, orderly, and safe place for its citizens. The government ensures access to basic necessities such as housing and healthcare, significantly reducing poverty and promoting equality. While personal freedoms may be limited, many Singaporeans find satisfaction in the stability and quality of life their country offers, showing that happiness can stem from collective security.

        In contrast, Mexico highlights the importance of social connections in achieving happiness. Despite challenges like poverty and limited access to essential resources, Mexicans often prioritize relationships with family, friends, and neighbors. Simple acts like sharing meals or gathering in the community foster a sense of belonging and emotional well-being. Psychologists have long noted that feeling part of a larger social group can be a powerful source of happiness, even when material wealth is scarce. For them, the joy derived from relationships often outweighs material concerns.

       The role of money in happiness, however, is often debated. In Mexico, many individuals live in similar financial conditions, reducing the pressure of economic competition. When neighbors lack expensive possessions, individuals are less likely to feel dissatisfied with their own circumstances. This suggests that relative wealth and equality may have a stronger influence on happiness than absolute income.

       Ultimately, there is no universal recipe for happiness. Factors like security, freedom, social bonds, and financial equality all play a role, but their importance varies depending on individual and cultural values. Happiness, therefore, remains a deeply personal and multifaceted pursuit, shaped by our unique perspectives and circumstances.
