this question kept my attention since I used to be a gymnast... I chose B.. i wish they all kept my attention haha

I like this question. It avoids the need to differentiate between 'Like' and 'As'. We know we have to use 'Like' so all that we need to do is see to that the sentence is not a clause but a phrase.

(A) those governing professional gymnastics, were motivated ['those' refers to rules or amendments?? Eliminated!]

(B) those to the rules governing professional gymnastics, were motivated [Correct! ]

(C) those to the rules which govern professional gymnastics, were motivated [ which govern is not parallel to rules governing. Eliminated!]

(D) the amendments to the rules governing professional gymnastics, have been motivated [implies that the motivation is still occuring. present perfect continous tense is not required. Eliminated!]

(E) the amendments governing professional gymnastics, were being motivated [implies something is working on the amendments. Eliminated!]

Hope this helps!

this question is testing parallelism and comparison

recent amendments to rules .... , like those . Hence D and E are ELIMINATED

Left with A , B and C

A compares the amendments to the governing rules. which is not the case here .ELIMINATE

C is not parallel with the underlined part of the sentence. ELIMINATE

B is the only one which compares the amendments to the rules governing ....with those to the rules governing .....
B also maintains parallelism

Hope this helps

recent amendments to the rules and like is comparing them so we will ave to take similar one for comparing it.
so B seems to be correct
A" it directly refers to governing professional gymnastics and not the rules

C" not parallel to first clause "governing professional baseball"
I don't think we are comparing amendments to amendments "D" and "E" out/....

Option D for the following reasons...

1. As the action has occurred in some indefinite time in the past....it will have present participle....
2. Like acts as a preposition , linking a relationship between two nouns...

I got it wrong. I picked up D but convinced with B. B fits the bill perfectly.

It must be present participle....
