Please make the following in bold clear for me.
1. Adult Americans spend billions of dollars and pass tens of billions of hours taking courses in the following.
*Giving up drugs *Giving up on people who take drugs *Drawing with the right hemisphere
2. By 1884, the asylums of Europe burst with men in the final stages of this disease(general paresis), shrieking obscenities. Controversy swirled over its cause.
Is this saying "the patients were saying obscene words loudly"?
Thank you for the answer.
