3. Class 12 English Unit 13 History: Critical Thinking Analysis

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.

Yes, it’s a tragic truth that many innocent people lose their lives in ruthless terrorist attacks every year. The government must be highly responsible to proactively handle and completely control such volatile situations. It should think very seriously about the national security of its citizens from such ruthless attacks. The critical steps the government should do to efficiently protect their people from such attacks and make the world a safer place to live are as follows:

• Every government should maintain solid political stability within their leadership and ruling parties to prevent internal chaos.
• Strict border restrictions and thorough screening processes should be systematically implemented.
• Highly trained armed forces and rapid response units should be kept on alert at several key places where there is a high risk of attack outbreaks.
• Though international peace treaties are constantly being signed, they are often not followed accordingly. So every nation should work transparently and cooperatively to maintain global peace through diplomacy.
• Efficient emergency evacuation protocols should be established so people can be moved to safer places quickly if there is any sudden danger.

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

Yes, I completely agree with the grim statement that revenge and violence are the integral, unavoidable parts of human history and civilization. Revenge is fundamentally associated with deep psychological hurt and emotional damage, and violence is the primitive use of physical force so as to injure, abuse, damage, or destroy the opposing party.

The root cause of World War II is a prime historical example; it was heavily fueled by the desire for revenge from Germany. On June 28, 1919, when the Treaty of Versailles was signed and the bloody war between Germany and the Allied Powers was ended, it severely humiliated and entirely blamed Germany for World War I, imposing crippling heavy debt payments. Germany intensely sought revenge for this humiliation, and in 1939, that boiling resentment started World War II. We have seen repeatedly from our dark past that cycles of revenge and violence always lead to a miserable, catastrophic situation for humanity. Thus, since it is a part of human nature, it can’t be completely ignored or erased, but it must be heavily managed through justice, diplomacy, and strong peacekeeping institutions.

4. Class 12 English Unit 13 History: Writing Tasks & Essays

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

(Here is a descriptive paragraph about a celestial event:)

Recently I witnessed a very special, breathtaking celestial event known globally as the full lunar eclipse. It was exceptionally special because expert astronomers declared it to be the longest lunar eclipse of this century, which took place on July 27. It was quite difficult for me because I had to forcibly stay awake until late at night just for watching this magnificent lunar eclipse. Finally, the anticipated eclipse started at 11:30 PM and beautifully concluded at 1 AM. I was warmly accompanied by a few enthusiastic friends who chose to witness this rare lunar eclipse together. We excitedly kept looking up into the clear night sky for one and a half hours, which was a bit physically straining on our necks but incredibly rewarding in the end.


B. Human life does not pass as one expects. You might have also gone through different but memorable incidents. Write an essay on “An Unforgettable Event in my Life’ in about 500 words.

(Here is an essay written by Aayush:)

An Unforgettable Event in my Life

It is profoundly true that if we have immense joys in our unpredictable life, we inevitably have deep sorrows too. Like all others, I cannot be an exception to this universal rule. I still vividly remember the tragic day when I felt that there is no joy in the world, only suffocating sorrow.

I was joyously enjoying the long vacations right after my tenth class board examinations. My best friend in the entire neighborhood, Alisha, was staying with me for a few days. Her loving parents had urgently gone to Kathmandu where her elderly grandfather was to undergo some major, life-saving operation. I and my parents did our absolute best to keep her happy and completely distracted from missing her parents. For us, it was carefree playtime all through the sunny day.

One quiet evening as we were intensely playing our little brain games, her parents called joyfully and said her grandfather’s operation was highly successful and her parents were scheduled to return the very next day by plane. On hearing it, Alisha was overjoyed and I happily joined her in her precious moment of happiness. That night Alisha did not sleep a wink. She excitedly counted the hours till the early morning light. We dressed hurriedly and my father kindly took us to the airport. On reaching there, we instantly sensed something horribly wrong. The Yeti Airlines flight from Kathmandu had tragically crashed while attempting to land. Loud fire tenders and screaming ambulances were desperately on the run. Our hearts completely sank. Alisha fainted from the sudden, unbearable shock. My father quickly hired a taxi and sadly sent us back home.

We nervously waited with violently throbbing hearts for my father to return with her safe and sound parents. My worried mother sent for a local doctor as Alisha’s fragile condition became worse. I sat silently by her side, desperately wishing for a happy turn of events. My father returned only to grimly say that there was no sign of her parents anywhere, though their names were clearly mentioned in the airline’s official passenger list. Alisha was hysterical and it became incredibly difficult to emotionally control her.

She tearfully said that she wanted to go back to her own home. I decided to loyally go with her while my mother would soon follow us. Once out on the busy street, she ran blindly towards her home in a state of shock. I saw a speeding car approaching and shouted loudly after her to stop. She didn’t hear me. The ruthless car didn’t stop and sped away, leaving her laying on the cold road, badly hurt. We immediately rushed her to a nearby hospital. The doctors who examined her grimly said she may recover gradually but did not confirm her full recovery. She was urgently placed in the intensive care unit.

I returned home silently with my parents. The exact moment we entered the room, the telephone rang loudly. It was a dreadful call from the hospital to inform us that Alisha was no more. I felt entirely numb and hot tears welled up in my eyes. I still stubbornly refused to believe what I heard was true. Again, the telephone rang, and miraculously, it was from Alisha’s parents to inform us that they had fortunately missed their doomed flight due to some sudden car trouble on their way to the airport. But the news of Alisha’s parents being alive did not touch my shattered heart.

Alisha’s parents were completely shocked and devastated to hear about their only daughter’s sudden death when they came home the next day. But nothing could be done to reverse fate. Even today, when I remember that cursed incident, every painful moment of that day flashes vividly through my eyes and I begin to cry, “Alisha, why did you have to die? I have lost a truly good friend in you.”

What are we seeing here? One very real possibility is that these are the educational consequences of the differences in parenting styles that we talked about in the Chris Langan chapter.

He gets taken to museums and gets enrolled in special programs and goes to summer camp, where he takes classes. When he’s bored at home, there are plenty of books to read, and his parents see it as their responsibility to keep him actively engaged in the world for him. It’s hard to see how Alex would get better at reading and math in the summer.
