Main questions thread

[PutraenusAlivius]

This is my main questions thread. I'll update the thread if I encounter any problems, so I don't have to create threads for each problem.
The problems I have are different problems (Like Modelling and Scripting)

MISCELLANEOUS ISSUE
1) At what year is Penicillin is discovered?
- 1a) At what year Penicillin is used commercially too?

2) Is it okay to consume a medicine that's roughly 1/4 of this bottle's
size?

3) Do most lamps use electricity as the power in 1890 and above?

4) Does some lanterns are old Oil Lantern's instead of Bulls Eye Lanterns?

And that's all I got.
