Is this argument valid If I dont get sleep then I wont be al

Is this argument valid?

\"If I don\'t get sleep, then I won\'t be alert. I don\'t get enough exercise. If I get sleep, then I will be rested. Either I\'m alert, or I get enough exercise (or both.) Hence, I will be rested.\"

Solution

we are given

\"If I don\'t get sleep, then I won\'t be alert.I don\'t get enough exercise\"

It means that \"If I get sleep , then I would be alert.I get enough exercise\"

sleep=alert=enough excercise

now, we are given

\"If I get sleep, then I will be rested\"

it means that

sleep= rested

so, sleep=rested =alert=enough excercise

In any one case , I get sleep

now, we have to prove

Either I\'m alert, or I get enough exercise (or both.)

It means I will be either alert or enough excercise or both

In all these cases , I get sleep

and If I get sleep , then I will be rested

Hence , I will be rested.....................Answer
