Read the following passage about powering 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.

     As we continue to face the impacts of climate change, having a green environment has become increasingly important to the future of our society. To achieve this, the world is shifting towards green energy, and two particular types of energy at the centre of this movement are solar power and wind power.

     [I] Solar power is all about harnessing the energy of the sun by using solar panels to convert sunlight into usable electricity. [II]. Moreover, solar panels are perfect for installation on a small scale, such as in private homes, since they require very little maintenance and have a long lifespan. [III] However, the ability to generate solar power depends on the time of day and weather conditions. This means that solar panels are often less useful if they are installed in places where sunny weather is not typical. [IV]

     Wind power, on the other hand, involves converting the energy of the wind into electricity using large turbines. Wind power doesn’t produce any greenhouse gases, but it is not ideal for private use since turbines require consistent care. However, wind farms can be installed on a large scale and are able to produce electricity continuously regardless of the time of day. This means that if there were more investments in wind power, it could be a viable way to provide energy for major cities and even for whole regions.

     Wind and solar power contribute significantly to a green environment by reducing our reliance on fossil fuels, helping us cut down on pollution and slow climate change. Additionally, using renewable energy sources helps promote spending on sustainable development by creating new career opportunities in the green energy sector.

     For now, the biggest challenge of adopting green energy is the costs associated with installation and infrastructure, but the benefits unquestionably outweigh the downsides. If we want to stop the climate crisis and create a better and more sustainable future, green energy sources will undoubtedly be the key.

Global Issues: Gender Equality and Women’s Empowerment

Gender equality means that men and women have equal power and equal opportunities for financial independence, education, and personal development. Women's empowerment is a critical aspect of achieving gender equality. It includes increasing a woman's sense of self-worth, her decision-making power, her access to opportunities and resources, her power and control over her own life inside and outside the home, and her ability to effect change. Yet gender issues are not focused on women alone, but on the relationship between men and women in society. The actions and attitudes of men and boys play an essential role in achieving gender equality.

Education is a key area of focus. Although the world is making progress in achieving gender parity in education, girls still make up a higher percentage of out-of-school children than boys. Approximately one quarter of girls in the developing world do not attend school. Typically, families with limited means who cannot afford costs such as school fees, uniforms, and supplies for all of their children will prioritize education for their sons. Families may also rely on girls' labor for household chores, carrying water, and childcare, leaving limited time for schooling. But prioritizing girls' education provides perhaps the single highest return on investment in the developing world. An educated girl is more likely to postpone marriage, raise a smaller family, have healthier children, and send her own children to school. She has more opportunities to earn an income and to participate in political processes, and she is less likely to become infected with HIV.

Women's health and safety is another important area. HIV/AIDS is becoming an increasingly impactful issue for women. This can be related to women having fewer opportunities for health education, unequal power in sexual partnership, or as a result of gender-based violence. Maternal health is also an issue of specific concern. In many countries, women have limited access to prenatal and infant care, and are more likely to experience complications during pregnancy and childbirth. This is a critical concern in countries where girls marry and have children before they are ready; often well before the age of 18. Quality maternal health care can provide an important entry point for information and services that empower mothers as informed decision-makers concerning their own health and the health of their children.

A final area of focus in attaining gender equality is women's economic and political empowerment. Though women comprise more than 50% of the world's population, they only own 1% of the world's wealth. Throughout the world, women and girls perform long hours of unpaid domestic work. In some places, women still lack rights to own land or to inherit property, obtain access to credit, earn income, or to move up in their workplace, free from job discrimination. At all levels, including at home and in the public arena, women are widely underrepresented as decision-makers. In legislatures around the world, women are outnumbered 4 to 1, yet women's political participation is crucial for achieving gender equality and genuine democracy.
