Sentence Correction

I have following 2 doubts. please help me resolve them

Exception to TOUCH rule (doesn't following statements contradict eachother)
MGMAT SC 4th ed. (pg-234): short predicate can separate noun & noun-modifier.
Ron's video(https://vimeo.com/11867667 at 1:38hrs): says following sentence is wrong because you cannot separate noun & noun modifier "I know more about Shakespear than my brother does, who has not studies british lecture."

Another doubt from same video at 1:38hrs:
a) I know more about Shakespear than does my brother
b) I know more about Shakespear than knows my brother
Ron says- a) is correct because we can put helping verb before subject but b) is wrong because we cannot put action verb before subject. However, we know that, in above context, "does" stands for "knows" OR "does==knows" then why there is difference in usage

I know more about Shakespeare than my brother does, who has not studies british lecture - where is the predicate here ?

If you go with the exact conversational definition of predicate : subject + predicate ( includes all that define or tell us more about the subject ), then you will realize that the whole concept of noun + noun modifier will not hold with the above mentioned rule. So the concept you are referring above do not consider this definition of predicate.

1.the attributes of a verb is determined by what follows the verb and not what comes before it ( in all active sentence).
2. "does" do not stand for "knows". when ever we use any action verb - we assume did/do. repeating "does" only help us to assume the action verb to follow.

In the above example :

1. I know more about Shakespeare than does my brother [know]
I know more about Shakespeare than my brother does [know]

In both these cases,"know",the main action verb, is assumed.

2. I know more about Shakespeare than knows my brother - here, "knows" being the original action verb ( the point of comparison) makes "my brother" the object of the verb. so this version would be correct -
I know more about Shakespeare than my brother knows.

hope this helps !!

She dances. - verb-only predicate https://en.wikipedia.org/wiki/Predicate_(grammar)
"brother does" is clause and "does" is predicate. in case you don't like "does" in above sentence consider this sentence from mgmat sc A new CEO has been hired who will transform the company. as per the ron's suggestion this sentence will be incorrect as well. i think that this rule is revised recently but will have to confirm from ron.

"does" do not stand for "knows". when ever we use any action verb - we assume did/do. repeating "does" only help us to assume the action verb to follow.
I know more about Shakespeare than does my brother [know]
I know more about Shakespeare than my brother does [know]

if we can use "do" then we can use "does" as well. they are singular-plural versions.
in any case, above sentences are not correct please see https://www.beatthegmat.com/halleya-s-co ... tml#468096

I know more about Shakespeare than knows my brother - here, "knows" being the original action verb ( the point of comparison) makes "my brother" the object of the verb.

this is incorrect because as per above quote gift is object but infact it is subject - in the presentation ceremony hall is your gift.
