I have to write a essay about the confederation of Canada in 1867 and why it was a good choice. I have all of my body paragraphs done but I'm having trouble thinking of a proper introduction.

My first sentence for my intro is: confederation was the best choice for the British colonies in 1867 for a number of reasons.
Now I need 2-3 sentences leading from general idea to specific which i need help on and I have a thesis statement but I'm not sure it's good enough so here is my thesis statement : Canada joined confederation because of better economy, better government and to defend against the USA.

So I need 2-3 sentences leading from the general idea to specific and is my opening sentence (intro) and my thesis statement good or should I change it. Please help this is due tomorow

You need to ditch that first sentence and revise the thesis.

I don't understand, my teacher said my intro sentence was good and my thesis was good, all I need is 2-3 sentences leading from general to specific

And that's y I posted the question because I don't get any help from websites, I need someone to show me

Like can you give me an example of an intro about confederation including my ideas and that will help me because I already have my body paragraphs done and all I need is the intro

No, I can't do that because that would be writing the paragraph for you.

I'm suggesting you ditch your first sentence because it's simply a repetition of your thesis.

If you cannot read and get information from websites that have helped countless other students, I really don't know what to say. But I won't write your sentences for you. Sorry.

All I needed were 2-3 sentences that's all, I'm not asking you to write my paragraph, I've written the entire essay but if you can't help with 2 sentences then there was no point in posting my question cause it was a waste of my time and I didn't receive help

The opening sentence in your introduction, "Confederation was the best choice for the British colonies in 1867 for a number of reasons," provides a general idea that sets the tone for your essay. To lead from this general idea to specific points, you can briefly mention the challenges faced by the British colonies at the time and how confederation addressed those issues. For example, you could say something like: "With the British colonies in North America facing economic hardships, political divisions, and the potential threat of expansionism from the United States, confederation emerged as a promising solution that offered a path towards a stronger, more united future."

As for your thesis statement, it is a good start as it outlines the main reasons why Canada joined confederation. However, it could be further improved by adding more specific language to make it more precise. For instance, you could highlight the specific aspects of the economy, government, and defense that were improved through confederation. This will help provide a clear roadmap for your essay and make your thesis statement more compelling.
