Final answer:
The three things that you cannot do are: meet Audrey Hepburn, meet Harry Houdini, and perform magic at the level of Houdini. Audrey Hepburn and Harry Houdini have long since passed, and matching Houdini's magic skills is highly unlikely.
Step-by-step explanation:
The question seems to be based on a mix of historical and cultural references, and it involves discerning which of the listed activities or experiences are impossible. Given the options provided, the correct answer would be: you cannot meet Audrey Hepburn, meet Harry Houdini, and perform magic like Houdini. Here's why: Audrey Hepburn passed away in 1993, making it impossible to meet her now; Harry Houdini, an illusionist and stunt performer, died in 1926, and so he cannot be met either. While you could learn to perform magic, it's unlikely that you could perform it to the same extent as Houdini, famous for his escape acts and illusions. However, anyone can play D&D (Dungeons & Dragons), read Fangoria magazine, and play croquet assuming they have the means and access to these activities.
