Problem: There are seven suburbicarian sees: Ostia, Albano, Porto and Santa Rufina, Palestrina, Sabina and Mentana, Frascati and Velletri. Velletri was united with Ostia from 1150 until 1914, when Pope Pius X separated them again, but decreed that whatever cardinal bishop became Dean of the College of Cardinals would keep the suburbicarian see he already held, adding to it that of Ostia, with the result that there continued to be only six cardinal bishops.
When were the two sees combined?

Problem: The ABS plastic used in the casing of some older SNES and Super Famicom consoles is particularly susceptible to oxidization on exposure to air, likely due to an incorrect mixture of the stabilizing or flame retarding additives. This, along with the particularly light color of the original plastic, causes affected consoles to quickly become yellow; if the sections of the casing came from different batches of plastic, a "two-tone" effect results. The color can sometimes be restored with UV light and a hydrogen peroxide solution.
What is caused due to an incorrect mixture of a hydrogen peroxide solution during manufacturing?
