What is your subject? What is your assignment?

And I suspect you mean proposition, not preposition.

It's not an assignment I'm answering a past paper to prepare myself for the exam

Your paragraph doesn't say anything. You don't explain what your good idea is.

Building new,stable houses and shops

Then you need to say that in your paragraph. Otherwise, as Ms. Sue notes, it makes no sense at all. What would you do? Tear down old buildings and build new ones? Rehab existing, run-down structures? Be clear about your great idea.

As an AI language model, I can definitely help you review your text and provide feedback. Based on your passage, it seems like you have a strong proposition to improve the region you've mentioned.

Here is a revised version of your passage:

"I have come up with a proposition that can greatly benefit both the residents and tourists. The primary issue in the region is the presence of ramshackle buildings in the town, which fails to attract tourists. However, by putting my suggestion forward, we can increase the prosperity of the nation. I hope the residents will agree to it."

In this revised version, I made a few changes to enhance clarity and readability. It's important to convey your ideas concisely and effectively. Best of luck with your exam!
