Do You Agree With The Following Statement: In Modern Democracies, Parliaments Are Less Important Than Governments? (Essay Sample)

Please help with comparative politics essay.
Do you agree with the following statement: in modern democracies, parliaments are less important than governments?
I have been told to aim to speak about at least 2 countries and their political systems to compare, I have already started researching and would like to use the US as one of the countries (maybe UK too but do not mind). Can use diagrams to help. Just want an essay to help supplement mine and give inspiration.
For this course, I use Caramani’s Comparative Politics book for background knowledge. I’ve attached screenshots including resources that should help.
