Explanation:

The word “impregnable” as used in this case refers to something being difficult to be captured or broken into. In this example, that word is used to describe the seemingly unbreakable subordination of the colonies before the American Revolution, which history has proven was only an obstacle plausible of being surpassed, just like woman suffrage is.
