physics question hard??

Two light circuits with identical lightbulbs. One has two lightbulbs in parallel. Other has them in series.

Student 1 says series will glow brighter cuz the same current goes to both lightbulbs.

Student 2 says parallel cuz the whole voltage of the battery goes to both bulbs, it's as if there's no other bulb. Also, the current used up in the series circuit so one light is dimmer.
State the flaws and correct points in their arguments.
 
b) 4 equations listed, which ones support which arguments?
Parallel voltage eq
Series voltage eq
Parallel current eq
Series current eq
 
C) what is the right answer? Justify
