Adding more premises to a valid deductive argument can make it go from valid to invalid cannot make it invalid can make the other premises true can make it inductively stronger

cannot make it invalid

Explanation:

A deductive argument is one in which the premises necessarily follow from the conclusion. This means that if the premises are true, the conclusion will also be true. So adding assumptions only reinforces the argument, it can never invalidate a dedutive argument.
