=>

A : The girl, who has golden hair, is my elder sister.

This is technically not incorrect but would probably be the incorrect answer on the GMAT because "who has golden hair" is an essential modifier
B : The girl who has golden hair is my elder sister.

Correct

C : The girl with golden hair, is my elder sister.

Incorrect

D : The girl with golden hair is my elder sister.

correct

E : The girl, with golden hair, is my elder sister.

incorrect, you can't use commas with essential modifiers

F : The girl, having golden hair is my elder sister.

incorrect, this is just bad...lol

G : The girl having golden hair is my elder sister.
I'm not sure, I would have to look this up


H : The girl, having golden hair, is my elder sister.
Incorrect, in this case "having golden hair is essential, so it shouldn't be set off by commas, but I am unsure if you can use a gerund to modify girl, I have to look that up

(the above one is the OA of a sample SC question.)

Now the below part in the above sentence

New Jersey, wildlife officials estimate, has

and the one in my example

temperature in US, estimated by scientists, is supposed to reach 30 degrees this year.

Are they different?

Ofcourse GMAT won't give such a simplified option in SC that you mentioned

"Scientists estimate that temperatures in the U.S. will reach 30 degrees this year." -- this simple will never be OA in GMAT

please explain? (mind that my first example is OA of a sample SC in GMAT, so cannot be wrong)

now is "scientists estimate" aside? "

Yes, this would be an acceptable aside. The past participle in the old sentence was "estimated" you can't lead with that unless it touches the noun or verb it was intended to modify.

Now as you said above ---can the below be "nonessential modifier"

Temperature in US, as scientists estimated, is supposed to reach 30 degrees this year.

or

Temperature in US, scientists estimated, is supposed to reach 30 degrees this year.

It touches the noun, right?
