Answer:
1. In building an argument I need to build a claim
2.To defend my stand on an issue I must collect evidence.
Explanation:
An argument is a position in relation to a relevant issue present in society, in some way. This positioning is established upon a claim, where the author of the argument will show how he interprets and views this issue, the problems it causes and the possible solutions. In order to defend this argument, it is necessary for the author to collect evidence, which is evidence that the position is correct and that it is relevant in today's society.
