Rahul Dravid, the head coach of India’s Under-19 cricket team, explained that the 2018 Under-19 World Cup team selection strategy was about providing opportunities to a lot more players to come into the India Under-19 fold. He explained that more than winning — which is not the right touchstone of success of a program at this level — what matters is how many of the players are able to move to the next level, which is playing first-class cricket. He, therefore, made a conscious decision to not select players from the previous World Cup to the 2018 Under-19 World Cup squad.
Which one of the following statements is consistent with Dravid’s selection strategy for the 2018 Under-19 World Cup as stated above?

Read the information carefully to answer the question.
Political turmoil in a country is mainly caused by widespread violence and flawed economic policies of successive governments. If at all this has to be crushed, it can be achieved only by a dictatorial government which rules with iron hand. Therefore, the need of the hour is to elect a government which imposes fresh set of stringent legislations. The alternatives suggested (not necessarily all), if true, considerably weaken the argument. However, one of them is most forceful. Identify the same.
In making a decision about an important question, it is desirable to distinguish between a 'strong' argument and a 'weak' argument. A 'strong' argument must be both important and directly related to the question. A 'weak' argument may not be directly related to the question and may be of minor importance or may be related to the trivial aspect of the question. The question below is followed by two arguments numbered I and II. You have to decide which of the arguments is 'strong' and which is 'weak'.
Statement
- Should all the factories in the cities be shifted to the outskirts, far away from the main city?
Arguments
- Yes, this is an essential Step for controlling pollution in the city.
- No, such a Step will lead to a lot of inconveniences to the employees of the factories and their families as well.
