a. Many innocent people lose their lives in ruthless attacks every year. What do you think the governments should do to protect their people from such attacks and make the world a safer place to live? Discuss with your friends.

Even though many citizens are murdered in brutal attacks every year, it is not desirable since the state must protect its citizens. A country's government is accountable for its citizens' safety and security.

Every country's government should be concerned about global security and work together to ensure everyone's safety. 

The government must protect the country and its residents from dangers such as foreign strikes and terrorist acts. A government is in charge of defense, foreign policy, national security, the economy, and social services.

The government should take several measures. Government should create courts and prisons, and elect or appoint people to pass and execute laws. Taxation should be utilized to support an army and police force.

Finally, the government should preserve peace and order, establish strict laws, aid its citizens, and protect the nation and its people.

b. Revenge and violence are integral parts of history and civilization. They can't be ignored, only managed. Do you agree or not with this statement? Present your logic.

Yes, I believe . Violence and vengeance have long been part of human civilization. Inaction may cause new issues for civilisation. They won't go away.

Victims of physical or verbal abuse want revenge. This provokes unpleasant feelings like rage and hatred. They are humiliated when made to feel weak, foolish, ignorant, or ashamed, and take revenge via violence.

Signed on June 28th, 1919, the Treaty of Versailles ended the war, but also humiliated and shamed Germany. It also obligated the German government financially. In 1939, Germany re-started WWII as a form of vengeance.

Revenge may be both good and harmful. Various types of violence include psychological, physical, and sexual assault. Violence is caused by biological, social, cognitive, and environmental factors. So, Revenge and violence are essential components of human history and civilization.


A. Write a description of an event that you have recently witnessed.

A few weeks back, I was walking to school at 8:00 a.m. As I walked near Bhrikuti Chowk, two young motorcycle’s crashed into a vehicle. The motorbike riders landed around four feet distant. One of the two young victims died there. The motorcyclist received a severe right-side head injury. Despite his injuries, he recovered. They were sent to hospital. This horrifying accident left me astonished and awed. That night I had nightmares. This is a past incident that still bothers me.

B. Human life does not pass as one expects. You can have also gone through various yet noteworthy experiences. Write an essay on 'An Unforgettable Event in my Life' in roughly 500 words.

'An Unforgettable Event in my Life'

This incident changed my life.

In 2019, I left for home at 10:30 after my night tuition classes. My way home was long and lonely. As I drove by, I saw four guys abusing a girl.

She was on a scooter and she braked forcefully to avoid hitting those men. They teased and stopped her. One of them instructed me to turn around and depart as I approached on my bike. 

I saw the female face as I was about to do a U-turn. Her cheeks swelled with worry and grief. She couldn't talk due to fear. I asked myself, Why do I leave her? In reality, there are four drunk guys, so I can't assist her.

These thoughts occurred to me instantly. After that, I got off my bike and raced straight to them, hitting the first guy in the stomach and throwing stones at the others. But, I could not defeat them as I am not a hero. My face, stomach, back and legs were all beaten. I shouted at the female to leave the place. She left quickly.

They continued pounding me, and I tried to defend myself but couldn't. Then they departed.

I escaped with minor bruises and no blood on my face. Then I went home and slept with pain and a smile for the first time.

Since then, I've defended and assisted others. Protecting others does not mean fighting physically, but rather sticking up for the one in need. Help can save a life. One need not be a hero or strong to fight evil.

What are we seeing here? The very real possibility is that these are the educational consequences of the differences between parenting styles that we talked about in the Chris Langan chapter. Think back to Alex Williams, the nine-year-old whom Annette Lareau studied. His parents believe in concerted cultivation. He gets taken into museums and gets enrolled in special programs and goes to summer camp, where he takes classes.
