Arguments (3), (4) and (5) do not talk about attracting customers. Hence, these are not strong arguments as they are irrelevant to the context. Moreover, argument (5) is a comparative one. Comparative arguments are not strong arguments. Argument (1) supports the statement by showing a reason for customers to get attracted. Argument (2) opposes the statement by indicating why the suggested action would not help in achieving the goal. Thus, arguments (1) and (2) are strong for their own reasons. If the given statement does not attach any purpose for the proposed action, the way we look at the argument changes. Now, observe how the previous statement is expressed. Statement: Should interest rates on bank deposits be increased? Analysis: Now, the question of relevance does not arise, because the statement does not attach any purpose for the suggested action, any purpose/ disadvantages of such action can be given as an argument. In any case, argument (5) is a weak argument because it is comparative. Argument (1) based its support on a positive result (attraction of new customers), which is beneficial to the bank. Hence, argument (1) is strong. Argument (2) suggests that the bank should concentrate on ensuring safety of funds, which is the need of the hour, but not increasing interest rates. In the present scenario, argument (2) is strong. Argument (3) bases itself on a negative effect that would follow such action. If interest rates on deposits are increased, banks tend to increase interest rates on advances as well, in order to maintain profitability. This leads to increase in cost of production. Ultimately, this leads to inflation. Here, we can see that the result obtained above logically follows the argument, as it is an established fact that increase in inflation is harmful to economy. Thus, argument (3) is strong. Argument (4) does not give any valid reason as to why the interest rates be increased due to increase in the interest rates on advances. Hence, argument (4) is weak. Before going to the exercise, let us summarise the above discussion. Summary: (1) A supporting argument bases its support on a positive result/effect that follows if the proposed action is implemented and an opposing argument bases itself on a negative result/effect. (2) The strength of an argument is checked through the following four steps. (i) Preliminary screening - Discard all such arguments which are ambiguous, simplistic, disproportionate, irrelevant or comparative. (ii) Truth in the argument – Check whether the result/effect discussed in the argument really follows. (iii) Desirability / Harmfulness - If the result / effect follows, check whether such result is really desirable/harmful. (3) An argument which is filtered through the above three steps is called a strong argument. (4) Take help of generally accepted facts, past experiences, etc., in analysing the strength of an argument.
