Question
Event (A): Researchers at
Bengaluru based Transdisciplinary University (TDU) have found that when water, inoculated with colony forming units of Escherichia coli, Salmonella Typhi and Vibrio cholerae, was stored overnight at room temperature in copper vessels, the organisms were no longer recoverable when cultured, compared to water stored in control glass bottles under similar conditions. Event (B): Recognising copper’s potential use in removing pathogens from water and making it fit to drink, Bengaluru based Transdisciplinary University (TDU) has launched TamRas, a low-cost copper-based water purification device for rural areas. Given below are pairs of events A and B. You have to read both the events A and B and decide their nature of relationship. You have to assume that the information given in A and B is true and you will not assume anything beyond the given information while deciding the answer. Mark answer.Solution
While Event (B) is an effect, the event (A) is not the primary cause of launching TamRas
