Hello Sakshi,

If the PDF is showing only the introduction, try these steps:

1. Redownload the file – The download might have been incomplete.
   
   
2. Open with another PDF viewer – Try using Adobe Reader or any other trusted PDF viewer.
   
   
3. Check the file size – If the file size is very small (a few KB), it might be a corrupted download.
   
   
4. Try opening on a different device – If possible, try accessing the file on another phone or computer.
   
   
5. Download from an alternative source – If available, try downloading the file from another link or website.

If the problem persists, share more details about the file or source.

I hope this answer helps you. If you have more queries, then feel free to share your questions with us, we will be happy to assist you.
