Read the following passage about the Science in Service of Humanity 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.

Science has come out of its shell in laboratories to become a powerful force for human advancement. Modern scientific endeavors increasingly focus on addressing real-world challenges affecting communities globally. From developing vaccines that save millions to creating technologies connecting people across continents, science serves humanity in countless ways. This shift represents a fundamental evolution in how we perceive scientific progress—not merely academic pursuit but a practical tool for improving lives and solving pressing problems.

[I] Medical breakthroughs exemplify how science directly benefits humanity. [II] For instance, gene therapy offers hope for those with inherited conditions, while artificial intelligence helps diagnose diseases earlier and more accurately. [III] These advancements didn't happen overnight; scientists had to burn the midnight oil for years before achieving success. [IV] Their perseverance demonstrates that when science targets humanitarian goals, results can transform society profoundly.

Environmental science has emerged as another crucial domain where laboratory work translates into human welfare. Climate scientists provide data informing policy decisions affecting billions. Conservation biologists develop strategies to protect biodiversity, ensuring future generations benefit from natural resources. Agricultural researchers create drought-resistant crops helping communities withstand changing climate conditions. Despite these contributions, environmental science faces challenges including funding limitations, political resistance, and urgency of addressing accelerating climate change. Nevertheless, dedicated scientists continue their work, recognizing environmental health directly impacts human wellbeing.

The future of science in service of humanity looks increasingly collaborative and inclusive. Modern approaches incorporate diverse perspectives, including indigenous knowledge and community participation. Citizen science projects engage non-professionals in data collection, democratizing the scientific process. Open-access publishing makes research findings available to anyone with internet access, not just wealthy institutions. These developments suggest science's greatest potential lies in becoming more accessible and responsive to human needs. As we face complex global challenges, from pandemics to climate change, science serving humanity offers our best hope for a sustainable future.

Read the passage carefully

1. No matter who we are or where we are from, we only have 24 hours each day to get things done. Some people seem to make the most of their time, using it to achieve their goals and dreams. Others feel that life is passing them by and they aren’t accomplishing anything. If you are in the latter group, it is not too late to turn things around. By implementing a few simple hacks, you can start getting better results very quickly.

2. If you want to become more productive, it pays to learn about the Pareto principle (which is also known as the 80-20 rule). It states that for most tasks, 80 percent of the results we get come from 20 percent of the work we do. For example. 80 percent of the company sales usually come from 20 percent of customers. Therefore, the trick is to focus your efforts on the key 20 percent of actions that truly matter to greatly improve your results.

3. In some cases, people may be busy from morning to night but still seem to get nothing done. In this situation, the problem might be that clear goals haven’t been set. To fix this, set some time aside to list the things you want to achieve in life. Then, select the top three or four that you want to focus on for the next year. Look at your goals every night before bedtime and ask yourself what are the next actions to accomplish each day. Then, promise yourself that you will finish these tasks no matter how busy you get. If possible try completing the tasks first thing in the morning so you are assured of success.

4. Another common mistake regarding productivity is not considering our energy levels. If we try to work around the clock, we will eventually get tired and quit. Everyone needs time to sleep, eat, socialize with friends, and unwind from the stress of the day. To make sure you don’t burn out, be sure to schedule some time for breaks and fun activities into your schedule every day. Finally, no matter how difficult your goals may seem, remember the old saying that “a journey of a thousand miles begins with a single step”.
