2nd time green card question

[fpvt2]

I have a friend who a few years ago came to the US with her green card and re-entry permit.
Because of the length of time she was outside the US, the officer at the airport told her to go to an immigration court to determine whether she could keep her green card or not.
Before the court date, her lawyer suggested her to return her green card voluntarily, so she returned her green card and I guess because of that she did not have to go to court.
In the future if she completes any US immigration form again (like if she wants to become a US permanent resident again), how shall she answers the following questions

1. Have you ever been refused admission to the United States at a port-of-entry?
If the answer is "yes" here because of the situation above, will this prevent her from getting the green card again ?

2. Have you ever been refused a U.S. Visa, been refused admission to the United States, or withdrawn your application for admission at the point of entry?
If the answer is "yes" here because of the situation above, will this prevent her from getting the green card again ?

3. Have you ever been under immigration proceeding ?
a. Removal
b. Exclusion/Deportation
c. Recission
d. Judicial Proceedings
If the answer is "yes" here because of the situation above, will this prevent her from getting the green card again ?

3. Has your U.S. Visa ever been cancelled or revoked?

Thank you.

After talking to her again, I wrote down a slightly different information.
At the airport the officer told her to go to the court to determine whether she could keep her green card or not (this is due to the length of time she was out of the US).
She did go to court, and at the court right away she and her lawyer told the court that she wants to surrender her green card.
The court then put a stamp on her passport saying how long she can stay in the US.

With this new information, the next time she wants to get a US visa or US permanent resident again, will it affect her case ?
And, how should she answer the below questions ?

1. Have you ever been refused admission to the United States at a port-of-entry?
If the answer is "yes" here because of the situation above, will this prevent her from getting the green card again ?

2. Have you ever been refused a U.S. Visa, been refused admission to the United States, or withdrawn your application for admission at the point of entry?
If the answer is "yes" here because of the situation above, will this prevent her from getting the green card again ?

3. Have you ever been under immigration proceeding ?
a. Removal
b. Exclusion/Deportation
c. Recission
d. Judicial Proceedings
If the answer is "yes" here because of the situation above, will this prevent her from getting the green card again ?

4. Has your U.S. Visa ever been cancelled or revoked?

Thank you
