Answer
The Argument is Modus Ponens,
The argument is valid
The conclusion is true because the Hypotheses are true.
Work Step by Step
Modus Ponens:
$$\displaylines{
p \to q \cr
p \cr} $$$$- - -$$$$\therefore q$$
Ans-
Let us assume:
p="Socrates is human"
q="Socrates is mortal"
Then we can write the given argument as
$$\displaylines{
p \to q \cr
p \cr} $$$$- - -$$$$\therefore q$$
The order of statements in the argument does not matter, so
$$\displaylines{
p \cr p \to q \cr} $$$$- - -$$$$\therefore q$$
Note that the conclusion is true according to the rule of Modus Ponens
