five out of 8.
This test is made by a self professed expert who really is a idiot.
1) Mail was available in the bigger cities. Yet it states. "Could you survive without free delivery of this item? If you lived before 1863, you'd have to." Yep, It truly existed before 1863. The criers of town would pass the mail while alerting the citizens of local news. (at least to the "elite citizens") Also The invention of the priniting press lead to the mass circulation of mail. As Captain Mike pointed out in his Luther Post.
Also Pauls (of NT fame) letters were mail sent via to other towns.
And Mail IS NOT FREE. We pay for it. hmm. Posting stamps, Bulk delivery, etc.
Where does this guy\gal live? Not reality.
3) Milk does take a day to spoil. I ges he\she never lived on a farm. What Did ancient Semetic people drink. Camels milk. What did 1800's people drink. Milk from thier Cow\goat\Horse.
And how did people make "soap, Cheese, Butter, etc?"
Also Wine skins. (hides made out of animal stomachs. Allowed milk or other beverages to last longer then a day.) So intestines served more of a purpose then guitar strings, Footbal skin, tennis string, etc.
4) While true Kitchens were seperate "areas" due to lack of ventilation, fire safety, etc. So was the outhouse.
