Lab Safety Questions

Hii...

A bit of an embarrassing question(s) that was not covered in class but presented on a Lab Safety quiz. I came here because I was unable to find the answers through my internet searches.
Would anyone be able to help me with these true or false questions?

When pouring a liquid into a graduated cylinder in the hood, the safest place for the graduated cylinder is on the front edge. True or False?

Weighing paper full of excess chemicals should be left by the balances.
True or False?

A reagent bottle must never be taken to your workbench. True or False?

It is not necessary to stir when two liquids are being mixed to form a solution. True or False?


Thanks!

I didn't find the right solution from the Internet.
