Wait.. What I wrote is this:
Take the initial volume of solution then subtract the final volume of solution (1) from it.
Now take the mass of radish and subtract the answer we got in (1)

I wrote the same thing.

I totally messed up with the Natural selection question[5mks]
But the paper was little bit hard compared to 2008.
Threshold will be 50/80 for A
