Solution

## The correct option is B True Lets denote the statements with symbols and analyse through a truthtable the possible truth value the statement can take. Once we do that we will be in a position to comment about the argument. Let, p → Dylan scores the first goal q → Dylan becomes man of the match r → Messi is injured The assumptions in the argument are, 1)p → q≡ S1 2)p v r≡ S2 3)∼q≡ S3 Conclusion is r ≡ S Given argument is S1,S2,S3 gives S. Lets construct the truth table. p q rS1 S2 S3S p→q p∨r ∼q(r)T T TT T FTT T FT T FFT F TF T TTT F FF T TFF T TT T FTF T FT F FFF F TT T TT⋯⋯⋯⋯⋯⋯⋯F F FT F TF The argument is valid when on the situation where all the assumptions are true the truth value of the conclusion should be TRUE for the argument to be true. This is the case here from 7th row. ∴ Argument is valid.  Suggest Corrections  0      Similar questions  Explore more
