Sentence Correction

For the following sentance, does the ING-modifer sentance modify "Mathematicians", or "test cases"? Experts please explain!

Mathematicians wrote test cases that are neither complicated nor simple, <insert ING modifier sentence here>.

VERB+ING Modifiers are of two types:
1. Adverbial = which modifies the complete clause; for example: Cause-Effect
2. Adjectival = which modifies the subject of the clause.

Can you please post the complete sentence.

Adjectival Modifiers are used to modify the Subject of the clause.
For example:
Being the expert int their domain, Mathematicians wrote the test cases that are very complicated.


Adverbial Modifiers are used to modify the complete clause.
For example:
Mathematicians wrote test cases that are very complicated, confusing the fellow students who are weak in that section.

Hi theCodetoGMAT,
For Adjectival Modifiers clauses, do they always have to be in the beginning and then followed by the subject-verb clause?
