Question 1177053
.


Questions  (a)  and  (b)  are to check if  YOU are able to read the text and to check 
if  YOU  are able  TO  UNDESRTAND  what you read.



Therefore,  these questions are addressed  DIRECTLY   to  YOU  and they can not be re-addressed to tutors.



I'd classified the two first questions as &nbsp;&nbsp;<U><I>I D I O T I C</I></U> &nbsp;&nbsp;for a &nbsp;Math problem 

and idiotic in degree &nbsp;2 &nbsp;(two, &nbsp;TWO) &nbsp;when you post them to tutors.



I do not recommend you to post idiotic questions to the forum.
