Deductive and inductive arguments when assessing the quality of an argument, we ask how well its premises support its conclusionmore specifically, we ask whether the argument is either deductively valid or inductively strong a deductive argument is an argument that is intended by the arguer to be deductively valid, that is, to provide a guarantee of the truth of the conclusion provided.

The argument is valid – if we accept the premises, we are forced to accept the conclusion however, the argument is not sound – oranges are not, in fact, green, so one of the premises is false this is a bad argument.
