You sound like you are whining a bit to be honest.
It is multiple choice. If you couldn't get one of their answers (even if their answers were all wrong) then you should have just guessed one and move on.
Raise the cost per packet to around $60 or so (this is what past papers have suggested it would take) to fully offset it. Then, through socioeconomic circumstances, people would over time purchase less of them (cigarettes).
I can smell the sarcasm. Hopefully "advise" was part of that also.
Knowing the difference between your and you're is important. Mess them up on your resume and you won't get the job.
