Explanation

The sentence has multiple errors including the use of redundant 'world' and parallelism: knowledge, mechanisms and thinking (two singular, one plural nouns). Also, the first two uses of 'perhaps' convey one idea (drawn upon), while the third conveys a different ideas. The third usage is like a new sentence and must at least begin with a semi colon. This option rectifies all the errors.
