Long Answer questions (120-150 words)

Answer: People of mars regarded Think-Tanks as the most powerful and clever person. Nobody questioned his orders.

He forced people to respect him. He had asked Noodle to pronounce complete salutation once again. He had smacked the mirror for being late in giving replies.

Think-Tank could not identify library. He called books as sandwich and asked his people to eat these. Noodle gave more information about books. Think-Tank acted as if he had thought over once again. Noodle had suggested that the crew should take vitamin tablets. But Thin-Tank ordered as if it was his own thought. So we can say that he always wanted to behave as the most intelligent person.

He knew nothing about nursery rhymes. But still he misinterpreted these. He ordered evacuation of Mars just for the sake of himself.

We can thus conclude that Think- Tank was arrogant, egoistic and self-anointed person.

Answer: Earth and Mars had different culture. Mars had a culture of a one person as the supreme. While it appears that such practice did not exist at earth.

While Earthlings were used to books and literature., the Martian did not know anything about books. There was no library at Mars where people could widen their awareness. They depended on wisdom of one person. Information was also centered at one place only. This resulted in a big confusion and Think-Tank evacuated Mars.

Differences in culture are bound to exist in our society. Routines and practices prevailing could be different. This creates confusion and sometimes a conflict may result.

However the need to co-exist is very important. We need to acknowledge routines of other society and explain our belief systems. This creates mutual respect and understanding.

If basic of culture and belief system is clearly understood and there is respect for each other, conflicts can be avoided.

Answer: None of us can know everything. Nor is it possible to know everything about even one particular aspect. Therefore we must seek clarification for whatever is not known.

Behaving as if we know everything, is the beginning of downfall. This leads us to making guesses or misinterpretation. In such situation our decision could go wrong. We become a laughing stock and do harm our own colleagues, family  and society.

Think-Tank is one such individual. He declared library as restaurant stand and book as sandwich. He changes his declarations to the extent Noodle suggests. It is a great embarrassment for everybody.

He does not know English language. He is unaware about poetry which is different from prose. He misinterprets every rhyme. He declares that Earthlings would capture Mars. So he runs away with every citizen of Mars.

Thus making conclusion without properly understanding the details can lead to wrong decision.
