Answer 1

Depends on whether this text is physically present on the page. That is, in HTML. If so, search engines will see it. In theory, of course, they can understand that it is not visible and score, but here I don’t know the exact algorithms

Answer 2

The webmaster consoles have a look through the eyes of a robot. And I would expect that there are separate pages where you can read further in full

Answer 3

Does the search engine index the text hidden under the scroll?

Depends on the implementation of the scroll.
Those. if the text covered by the scroll is displayed in the source code of the page, then it is indexed by search engines.
How to check:
Method number 1

1. Option 1 find the part of the text closed by the scroll by visually viewing the code. To do this, open the URL of the page in the browser, press the buttons on the keyboard Ctrl + U, the page source code will appear in the tab that opens.
   
2. Option 2 open the URL of the page in the browser, press the buttons on the keyboard Ctrl + U, the page source code will appear in the tab that opens. Click on the F3 key and in the search box that appears, paste a small part of the text from what is closed by the scroll. After pasting, press the Enter key. The text you entered will be highlighted in the source code on the page, if it is present there.
   

Method number 2
Check if the text is in the index of search engines. To do this, copy a small part of the text that is closed by the scroll and paste one by one into the Yandex/Google search bar by clicking on the "Find" button after pasting. As a result, search engines have to show where a given piece of text is located.
The nuances of this method

• You can see only those pages that have been indexed by search engines. New, not indexed pages - you will not see.
  
• Also, you will not see the text that was recently placed on the page of your site and has not yet been reindexed along with the page.
