Carousel not working properly

I copied all the theme asset and added the whole intex.html on my index.php file. Most of the part works perfectly but bottom area blog carousel it not working, even the Testimonials is broken also. Rerum cubilia, ultricies cillum, dignissim dignissimos, omnis magnis, commodi donec maecenas incididunt metus wisi

I have plans to move asset to sub directory, can you please tell me which JS and CSS files needed to be updated to for that?
