BunuelIndustrial discharge is one primary cause of water pollution and drinking such contaminated water results in numerous diseases in all living beings. Mixing Alum in water is an effective way to make these pollutants settle at the bottom of the water body, ensuring that more than 98% of the water – including the surface water – is potable. In order to reduce the incidence of water-borne diseases, the government plans to setup huge Alum manufacturing plants and to mix the produced Alum in all water bodies daily throughout the country.
Which of the following, if true, provides the best support for the assertion that the Government’s plan, if implemented, is likely to achieve its goal?
The primary focus of the argument is to reduce the incidence of water-borne diseases by setting up Alum manufacturing plants.A. Cost of manufacturing Alum and using it to remove the pollutants is much higher than the usage of Reverse Osmosis to clean water.--->
Clearly weakens the arguementB. Alum can be utilized – to some extent – to reduce air pollution too.--->
Okay but the government is concerned regarding water-borne diseases and not others. So out.C. Even in excess amounts, Alum is not likely to encourage the growth of any disease-causing factors in water.--->
Yes good choice. Even if the excess Alum amount is not causing any harm and preventing the growth of diseases it's going according to what the government has planned.D. The by-products of the Alum manufacturing process can act as excellent fertilizers for crops in flood conditions.--->
Okay but again we're asked to focus on reducing water-borne diseases and making the water potable by-products isn't the main concern E. Alum-manufacturing plants release considerably less amount of pollutants into water than other industries do.--->
Unrelated to the argument.
