This puzzle is part of the Monthly Topic Challenge #2: IQ Puzzle Parody
I've been sent an IQ test by a friend (because that's a really normal thing for friends to do) and I just can't work out what's going on. If anything, it looks to me like it's been corrupted or something:
I'm not the brightest cookie in the drawer, so I'd really appreciate it if someone could help me understand what's going on here so 'my friend' can give me a job in banking (because that's also a really normal thing for friends to do).
Maybe if you could explain it to me in a single word, just to keep things really simple? Thanks.
TASK: Deduce - with full explanation - the 8-letter solution to this puzzle. (NB All background is just for flavour - at least that's what my friend told me to tell you...)
