QUESTION ID:1
Read the given passage carefully and answer the questions that follow
The colour photograph of Earthrise, taken by Apollo 8 astronaut William A. Anders on December 24, 1968, is a powerful and eloquent image. One leading environmentalist has rightfully described it as "the most influential environmental photograph ever taken". Inspired by the photograph, economist Kenneth E. Boulding summed up the finite nature of our planet as viewed in the context of the vast expanse of space in his metaphor "Spaceship Earth". What had been perceived throughout human history as a limitless frontier had suddenly become a tiny sphere: limited in its resources, crowded by an ever-expanding human population, and threatened by our use of the atmosphere and the oceans as repositories for our consumptive wastes.
Perception about the planet Earth is that, it is a

The fermentation products prior to 1900 AD were confined to potable alcohol and vinegar. However, the first true large-scale breweries date from the 1700s AD when wooden vats of 1500 barrels capacity were introduced. By the mid-1800s AD, the role of yeasts in alcohol fermentation had been demonstrated independently by Cagniard-Latour, Schwann and Kutzing but it was Louis Pasteur who convinced the scientific world of the obligatory role of micro-organisms in the process. During the 1800s AD, Hansen started his pioneering work for isolating and propagating single yeast cells to produce pure culture. However, many traditional ale-producing breweries still use mixed yeast cultures. Vinegar was originally produced by leaving wine in shallow bowls or partially filled barrels where it was slowly oxidized to vinegar by the development of natural flora. The appreciation of the importance of air in the process led to the development of the 'generator'. Between the years, 1900 AD and 1940 AD, themost important advances were the development in the baker's yeast, solvent fermentation, citric acid production and lactic acid production.
