Hello yektadg,
1. What do these two words mean? pros,cons
Navigate to Theme Settings > Single Product > Reviews > disable Pros and cons
option.
2. How to add email and name to comments?
It requires custom coding, which is outside our scope of support. For specialized assistance and potential solutions, I kindly suggest that you reach out directly to the WooCommerce plugin’s support team https://wordpress.org/support/plugin/woocommerce/, who are better equipped to provide you with the guidance you requires or You need to find a third party plugin to achieve more functionality that best suits you.
Regards,
