How are the constitutions of England and America amended, and what are the key differences in their amendment processes?

let's finish these up.

e) The amendment procedure for the constitution of England is not a single, codified process. Since it is an unwritten constitution, it can be amended through ordinary acts of Parliament, judicial decisions, and the evolution of constitutional conventions. There is no special procedure distinct from regular law-making.

f) The American constitution is a rigid one. It requires a complex and difficult process involving supermajorities in both Congress and state legislatures to amend.
