Question

The authors of the text conclude that the question of whether and how the states should regulate abortion will inevitably be decided in favor of those claiming that a right to abortion exists

Answer 1

An abortion that occurs spontaneously is also known as a miscarriage. An abortion may be caused purposely and is then called an induced abortion, or less frequently, "induced miscarriage". The word abortion is often used to mean only induced abortions. I hope this helps. :)
