Last question (Scarecrow) one was funny. Also, how did everyone test for carbon dioxide rate?

Oh yeah diarrhoea one was odd. I couldn’t think of much sk just said water loves by osmosis from blood into intestine due to higher conc of sugar in intestine. Therefore faeces more dilute.

I thought of that then realised it would just be testing gas rate in general and not specifically CO2. Not sure tho
