Answer for How can I use the theme in two languages?

Hello, I think it’s not a good idea to install two WordPress sites. You will post an article two times for each site. If you use sub-domain such as en.site.com, which maybe be consider as an independent site. I think it’s not good for SEO. I suggest you use sub-folder such as site.com/en/ if you decide to  install two sites.
 
“Name”, “Email Address”, “Subject” and “Message” are the texts of placeholder for Contact section.
 
Thanks!
