Let’s dissect the sentence:
This began is the first part. In the example, we don’t know what began what, but we only need to know the part that it began for the sentence to make sense (as long as it has proper context.
the transformation of comes next, which means first that there will be a noun following that has been changed in the way, and second the word “of” describes that a preposition will follow, becoming the noun that the transformation happened to.
Kankakee’s general education track, although it is made up of three words, describes one noun. Kankakee’s means that it is something that Kankakee has possession of. general is a sneaky adjective that may look like a noun, but it means in this case the overall or unabridged education track, which is the actual noun, and describes the path Kankakee will take through education and school and/or college.
Finally, into the College and Career Academy describes a specific noun that he/she is beginning.
So in summary, this (an untold event) began Kankakee’s overall journey through the education of the College and Career Academy.
Hope this helped!
