IGNOU MCA -mcs-015 solved assignments 2012 -2013

Course Code : MCS-015
Course Title : Communication Skills
Assignment Number : MCA(1)/015/Assign/12
Assignment Marks : 100
Weightage : 25%
Last Dates for Submission : 15th October, 2012 (For July 2012 Session)
15th April, 2013 (For January 2013 Session)
 

This assignment has seven questions. Answer all questions. Please go through the guidelines regarding assignments given in the Programme Guide for the format of presentation.
 

Question 1: Read the passage below and answer the questions that follow:
A tribal elder in southern India, a Bollywood star, a young villager. One uses an ingenious piece of bent wire, the second a high-powered rifle, and the last, a jaw trap. The first may make a meal of his catch, the second may carry home the antlers as trophy and the third may sell the skin and bones to a trader.
Hunting is perhaps one of the oldest ways in which humans have interacted with wildlife. Over time, as we honed this ancient skill, we systematically drove several animals to extinction. Mastodons, woolly mammoths and moas (giant, flightless birds that lived in New Zealand until the 15th century) were all given the final shove by human hunters unaided by guns or gunpowder. With modern weapons in hand, we did even better. Passenger pigeons, whose massive flocks once darkened American skies, were shot in thousands in the presumption that they could never become extinct. But they did.
Closer home, the wolf and tiger teeter on the brink. Their once vast ranges are now mere fragments but still, neither they nor their prey are safe from poison, snare or shotgun.
All of this takes place despite some of the most stringent wildlife protection laws in the world. Most hunting was outlawed in India in 1972. Overnight, an activity with complex social and cultural roots became illegal. In some places, the law combined with modern forms of recreation to draw people away from hunting, but has not been able to stop it completely. Despite the widespread availability of affordable farmed meat, hunting for the pot continues because of strong cultural preferences for wild meat.
Despite such strong social, economic and cultural roots, we still treat elimination of hunting entirely as a law-enforcement exercise. And this task is in the hands of ill-equipped, poorly-motivated and sometimes corrupt forest department personnel who don‟t always make the best guardians of the law.
Alongside enforcement, the law needs widespread public support which can come only if the socio-economic factors of hunting are addressed. Shooting suspected poachers at sight may have helped reduce hunting in Kaziranga but this strategy
13
might not work everywhere. In the Periyar Tiger Reserve, former poachers have been trained and inducted as wildlife guides, providing them an alternative livelihood. In Namdapha Tiger Reserve, addressing a traditional hunting community‟s needs in education, healthcare and livelihood has helped secure their support for the law. These are clear pointers to securing the future of our wildlife – by building context-specific solutions to make hunting implausible and unviable, rather than just illegal.
 

a) What is common between a tribal, a Bollywood star and a young
villager according to the passage? (2 marks)
b) List four animals/birds that have become extinct due to human
intervention. (2 marks)
c) Why is hunting prevalent in India despite strong legislation? (3 marks)
d) What were the measures taken in the three wildlife sanctuaries to
stop hunting? (3 marks)
e) Give a suitable title to the passage. (2 marks)
f) Given below are the meanings of some words/phrases from the
passage. Pick out those words/phrases from the text: (8 marks)
i A very clever device
ii Branched horns on the head of a deer
iii Developed and improved
iv Total destruction
v Ultimate push
vi A situation that is close to becoming disastrous
vii A trap for catching birds or small animals
viii Very strictly enforced law
 



Question 2: Fill in the blanks using the passive forms. One is done for
you as an example. (10 marks)
Rohit Chauhan was just sent (send) to prison. Yesterday he (give)……….. a 6-month sentence for stealing a car. The conditions in the prison are terrible. Rohit (3 shock)………………. by them.
