How to translate this English sentence and find the structure (subject-predicate-object complement and clause) in the sentence?

Sentences and structures can be divided,

I (subject) is moving towards me (object) through Colombian infinity (preposition).

When I was still dealing with the problem, I was surrounded by students who quickly provided oral answers with an attributive clause that modified the infinity of Colombia.

In this clause, when I was still dealing with the problem, who quickly provided the oral answer was an attributive clause that modified the students.
