Answer:
Legend:
In the 1820s, the Bavarian astronomer Franz Von Paula Gruithuisen claimed to have glimpsed entire cities on the moon with his telescope. He wrote that the ‘lunarians who lived there had built sophisticated buildings, roads and forts. Most of his colleagues scoffed at his assertion, but he eventually got a small lunar crater named after him.

Sir William Herschel, a prominent British astronomer and composer, also thought aliens lived on the moon and made regular observations about the progress of their construction projects. In 1835, when the New York Sun published a series of fraudulent articles about the supposed existence of life on earth on the moon (pulling off the so-called “Great Moon Hoax”), it falsely credited Herschel’s son John, a famous astronomer in his own right, with the shocking discovery.

The Silver House Summary in English

Paraphrase:

The poet John Lea is comparing the silver house in the sky to a moon. He describes the different phases of the moon as the time to build up and pull down the said ‘Silver House’.

The poet talks about a man that lives in the ‘Silver House’ and how no one knows or talks about the man. The poet further advises us to draw the window blind at night, before calling it a day, in order to see the lonely man. John Lea, the poet, states that if you cease to find the poor man in the sky, it is because the ‘Silver House’ has been taken down. The ‘Silver House’ will of course not be there due to the moon being in the ‘new moon’ phase.

Introduction:

The poem The Silver House’ is a poem written by the poet John Lea that indirectly describes the phases of the moon.

Writing Skills.

Question 1.
Write an essay on: ‘Service to Humanity is Service to God’
Answer:
Woodrow Wilson has rightly said, “There is no higher religion than human service.” To work for the common good is the greatest creed.”

Our life acquires meaning only when we commit it towards the service of others. Love, care, compassion, kindness, empathy, sympathy, etc., are some of the vital values which will help us to reach out to those in need or to those in distress. There are several social workers who have committed their life in service of others. Whether it is Mother Teresa, Baba Amte, or Sant Cadge Maharaj, one thing they had in common was the unconditional love they had for their fellow beings.

We can make a world of difference by joining NGOs or participating in our school’s initiatives towards social work. Visiting home for the aged and spending time with the elderly, distributing gifts to the children in orphanages on our birthday, etc., are little acts of kindness which can make a big difference.

Let us remember the words of Mahatma Gandhi: “The best way to find yourself is to lose yourself in the service of others”. With a heart filled with generosity, with words that are kind and through acts of selflessness, let us build a world where love and happiness reign supreme.

Quote of the Day.

1. your care for compassion

Answer:
The August 1883 eruption that took place was the worst of the eruptions that took place. The sound of the volcanic eruption was heard more than 3500 kms away in Australia. The island which was a volcanic mountain, collapsed on itself. The dust rose up to 80 km. in the sky, which spread around the world and later settled in different parts thousands of kilometres away.

Giant tsunamis were caused by the eruption, destroying 165 villages and towns. Two-thirds of the island of Krakatoa was destroyed, which collapsed beneath the surface of the sea creating more than a 6 km. wide hole.

Question 2.
The living world on Rakata
Answer:
Rakata, a part of Krakatoa is still visible in the sea, a little away from Anak Krakatoa. After the 1883 eruption, all the surrounding islands and coasts were covered with hot ash rendering the island lifeless. In 1884, a scientist found only one spider when he visited Rakata.

The wind and the sea brought seeds of the plants to the island. Plants and animals that lived in the sea came to the coasts again. Small land animals like ants, termites or even rats and lizards travelled to the island on plants floating in the sea. One edge of the island was soon teeming with plants and animals.
