Collateral. You can borrow money against a house or car, but if you default and don't pay it back you will lose the house or car, or whatever you used as collateral.
In 1907, Britain, France and Russia formed a military alliance for WWI, known as the Triple Entente.
Answer: When a neighboring state changes a law, those that are violating it will either cease or move. In this case, a same sex couple will most likely move to a neighboring state (unless they want to try to put up a fight with the officials). Then that state may be influenced and copy that law banning same sex marriage. The more this happens, states that don`t ban it will be "safe-states" for those couples. This process may continue and affect even more neighboring states. In fact, it can happen with any law. I`m not all that smart on this subject, and I would paste the link here, but Brainly won`t let me. Hope this helped, if not comment if you have questions
