i also attempted the same topic (internet - a blessing or a bane)
As far as my expansion is concerned, i explained first that internet is the most remarkable invention of the last century ..... it has many benefits but the misuse of it has made it bane for us as our youth.... but still its benefits are much more than its disadvantages. then i explained some of the many benefits. in the end i said it is not the internet but it is the use of internet which makes it bane or blessing for us ..........
i thought at that time (very short time in fact) that the examiner was asking to take a stance and was asking to defend it.
i tackled it like that so i do not know whether it was right or wrong way to do it
