how can i still go on yahoo answers even when it's shut down?

You cant once its Gone on May 4,2021 if you type it in you will be Redirected back to Yahoo's Home Page 

Quora is literally the closest thing that is also as popular as Yahoo Answers. However it is very strict and trolls may find it hard to enjoy their time there. They are even more authoritarian than Yahoo as they (Quora admins) delete and merge questions at their own pleasure.

I dunno either I’m trying to research this myself & find out what a good alternative to yahoo answers would be so I can find another site that offers this service.

My advice simply do the research by yahoo, google, or any other search engine and type in “sites similar to yahoo answers”.

Usually if you use search engines like that when querying anything like this about other sites or topics usually good results come up

i dont think so, wish we could

you wont be able to when it shuts down

You can try on the Internet Wayback Machine.
