tautology which means something is absoultely correct but do not have any meaning

 

for example : my mom is a woman.

 

everyone knows that mom must be a woman, no one can doubt this fact

 

it seems so easy to know but how come when i having this quection in economics

 

i answer it wrongly

 

why a high school student need to study in an univerity level

 

the most funnest thing is that the first chapter you don't know what is it talking about

 

and the next chapter said that "the first chapter is very difficult to understand and if you don't know the meaning then is fine , you can skip it.

 

what the damn shit text book!

 

i am mad
