Does Babylon's wonder count for scientific structure victory points?
Babylon's A second stage (or B's third stage) allows you to get one scientific symbol of your choice at the end of the game, if you have built it. If you do, it counts for the scientific points. It works exactly like the Scientific purple card "Scientists' Guild".

Example: you have 4 "Gear" green cards and build Babylon's 2nd stage. You can convert it to a 5th "Gear" at the end of the game and earn a total of 25 points for 5 same green cards.
