LIFE,LANGUAGE AND CULTURE EXPLORATION-II (with project) key

LIFE,LANGUAGE AND CULTURE EXPLORATION-II key (with project)

1. MORNING BELLS 

-Jayashree Mohanraj

1.What do rag pickers do?

ans. Rag pickers wake up early in the morning, go from garbage bin to garbage bin filling their jute sacks with the materiallike broken plastics, tins, cans and bottles which they think could fetch them some money.

2.How did Chotu, Ramu, Irfan and Munna come together?

ans. They came together by providence. Chotu ran away from home; Ramu was sent away; Irfan and Munna don’t have ahome at all. All four of them once met at a dumping yard and started to live together. 

3.Why was the old municipal sweeper kind to them? 

ans.The sweeper would have felt bad for their lives and hence has been kind to them. He extended the help he could do to them. 

4.What did Chotu discover inside the garbage bin?

ans. Chotu discovered an infant in the garbage bin. He found it while he was searching the bin. 

5.Why had the female infant supposedly been left there?

ans. It might have been an unwanted child, may be a result of pre/extra marital relation or might because it’s a female child.Many families in our society don’t accept a female child. 

6.What did Ramu do with it?

ans. Ramu bent into the bin and gathered the infant in his hand. They wrapped it in an old news paper and put the bundle in thejute sack. 

7.Where did they go with the small bundle?

ans. They went to the abandoned car shed which happens to be their home. 

8.Why were people going to the temple?

ans. People go to temple for many reasons. Be it like – to seek blessings, to wash off their sins, to satisfy them selves for being so devotional, to impress others by being pious, and to attain peace of mind….etc. 

9.Why did one of the beggars want to adopt Ramu?

ans. One of the beggars had taken fancy for Ramu. He wanted to adopt him because he has no one living with him. He wanted to make Ramu his son, so that he would get some company and also that he could take a break once in a while, assigning his duty to Ramu. 

10.What did Chotu buy outside the temple? 

ans. Chotu bought some flowers and a few incense sticks. 

11.What did they do with the body of Chutky? 

ans. They dug a pit in one corner of the shed, placed the body in the pit and coveredwith mud. They kneeled beside the pit, put flowers, lit incense sticks and prayed a moment for her soul to rest in peace. 

12.What message do you get from the story?

ans. - The real prayer lies in empathy and sympathy for others. 
- One should never forget the humanitarian principles and values. 
- A minor positive action is better than a huge improper behavior
 - Small deeds done are better than great deeds planned.

2. The Rights of the child

3. Eco-friendly Garbage Management

4. Dial 000
