    I put that they were too large and blocked the x rays? Was a stab in the dark really.

    EDIT: Just did some googling and it seems that molecules in the air (especially nitrogen and oxygen) can absorb x rays.

    Can someone compile an unofficial mark scheme?

    I'd say similar to the first paper. Most people seemed to find these papers easier than last years though so probably higher boundaries than last year.
