IGNOU B.Ed. Entrance Exam Previous Year Question Paper 2021 With Answer Key

IGNOU B.Ed. Entrance Exam-2021

PART-A

Section-I General English Comprehension

Directions (Qs. No. 1-10): Read the following passage carefully and choose the best answer out of the four choices given after each question that follows:

     Nature is like business. Business sense dictates that we guard our capital and live from the interest. Nature’s capital is the enormous diversity of living things. Without it, the cannot feed ourselves, cure ourselves of illness or provide industry with the raw materials of wealth creation. Professor Edward Wilson of Harvard University, says: “The folly our descendants are least likely to forgive us is the ongoing loss of genetic and species diversity. This will take millions of years to correct.”

     Only 150 plant species have ever been widely cultivated. Yet over 75,000 edible plants are known in the wild. In a hungry world, with a population growing by 90 million each year, so much wasted potential is tragic. Medicines from the wild are worth around 40 billion dollars a year. Over 5000 species are known to yield chemical with cancer fighting potential. Scientists currently estimate that the total number of species in the world is between 10-30 million with only around 1.4 million identified.

     The web of life is torn when human beings exploit natural resources in short-sighted ways. The trade in tropical hardwoods can destroy whole forests to extract just a few commercially attractive specimens. Bad agricultural practices trigger 24 billion tonnes of top soil erosion a year losing the equivalent of 9 million tonnes of grain output. Cutting this kind of unsuitable exploitation and institution “sustainable utilization” will help turn the environmental crisis around.
