I was playing an online treasure hunt and came across a question with image.
cant pst that image here becoz i'm a newbie
clues
1.its a 4 letter word
2.two letters are 'R' and 'S' (S from star)
3.Think Science and technology
Maybe if you post in a better format we'll be able to help you; something like:
_R_S
__RS
etc.
So we can get a better idea. Think Scrabble.
