Question
In the question below, a situation is given, followed by
two statements (1) and (2). You have to take the given statements to be true even if they seem to be at variance from commonly known facts. Carefully analyse the situation, and choose the option that depicts the correct relationship between the statements and situation. Situation: Researchers from Australia announced recently that they used a graphene-based product to make a water filter that can make highly-polluted sea water drinkable after just one pass. Statement 1: While graphene allows water to pass through it, it is almost completely impervious to liquids and gases (even relatively small helium molecules). Statement 2: Graphene has been described as the strongest material ever tested, almost 300 times stronger than steel.Solution
The situation tells us that graphene has been used to make a highly efficient water filter. 1 gives us the cause for using graphene to make it - it gives us a property of the substance that would be useful for this application to be successful. 2 is unrelated as it gives an additional property of the material, which would not play a role in making it a good choice for a water filter system. Thus, (d) is the right answer.
