No crossovers or red herrings that I could see which made this very easy. No guessing or multiple attempts required. Beta blockers was a very obvious group despite not knowing what they were. I was half expecting it not to be a group. Drugs or medications should be an acceptable answer for that group though, we're not all doctors or need our betas blocked. Especially as medications is written in your answer. I didn't dislike it. It just wasn't a challenge.
