Comprehension Test Questions and Answers Practice Question and Answer

Q:

Read the passage carefully and give the answer of following questions.
A glass bottle that is sent to a landfill can take up to a million years to break down. By contrast, it takes as little as 30 days for a recycled glass bottle to leave your kitchen recycling bin and appear on a store shelf as a new glass container. Glass container are 100 percent recyclable, which means they can be recyclable repeatedly, again and again, with no loss of purify or quality in the glass. Recovered glass from glass recycling is the primary ingredient in all new glass containers. A typical glass container is made of as much as 70 percent recycled glass. According to industry estimates, 80 percent of all recycled glass eventually ends up as new glass containers. Every ton of glass that is recycled save more than a ton of the raw materials needed to create new glass, including 13,00 pounds of sand, 410 pounds of soda ash, and 380 pounds of limestone.
Because glass is made from natural materials such as sand and limestones, glass containers have a low rate of chemical interaction with their contents. As a result, glass can be safety reused.
Besides serving as the primary ingredient in new glass containers, recycled glass also has many other commercial uses-from creating decorative tiles and landscaping materials to rebuilding eroded beaches.

Answer : 3. "environment"

Q:

Read the following passage carefully and give the answer of following questions.

The problem of water pollution by pesticides can be understood only in context, as part of the whole to which it belongs – the pollution of the total environment of mankind. The pollution entering our waterways comes from many sources, radioactive wastes from reactors, laboratories and hospitals; fallout from nuclear explosions; domestic wastes from cities and towns; chemical wastes from factories. To these is a added a new kid of fallout - the chemical sprays applied to crop lands and gardens, forests and fields. Many of the chemical agents in this alarming melange initiate and augment the harmful effects of radiation, and within the groups of chemicals themselves there are sinister and little - understood interactions, transformations and summations of effect.

Ever since the chemists began to manufacture substances that nature never invented, the problem of water purification have become complex and the danger to users of water has increased. As we have seen, the production of these synthetic chemicals in large volume began in the 1940’s. It has now reached such proportion that an appalling deluge of chemical pollution is daily poured into the nation’s waterways. When inextricably mixed with domestic and other wastes discharged into the same water, these chemicals sometimes defy detection by the methods in ordinary use by purification plants. Most of them are so complex that they cannot be identified. In rivers, a really incredible variety of pollutants combine to produce deposits that sanitary engineers can only despairingly refer to as “gunk”.
