Question 2

What would you do if you become invisible? Would you use your invisibility to play tricks on people or for the good of people?

Write a short paragraph on 'If I were invisible'.

Solution:

If I were to gain the power of invisibility, I would prioritize using this extraordinary ability for the betterment of society rather than for personal amusement or mischief. My primary focus would be on observing and intervening in situations where wrongdoing occurs unnoticed. For instance, I would discreetly monitor areas frequented by anti-social elements to deter them from committing crimes and prevent potential harm to innocent citizens. Similarly, I would use my invisibility to thwart any clandestine activities or untoward attempts by terrorists, thereby contributing to public safety. Furthermore, I would visit public offices and institutions, including hospitals and factories, to ensure that authorities and professionals are performing their duties diligently and ethically. This would involve checking if doctors are treating patients properly, if child labor is being practiced, or if any other form of exploitation is taking place. By acting as an unseen guardian, I would strive to fight against societal evils and work towards creating a more just and equitable environment for everyone.
