Protecting some content on a page from view by the general public

I am using Membership to create access levels for registered members. I have a page that has two kinds of content. The first kind of content is not protected by the plugin and viewable by the general public. The second kind of content (shown highlighted in blue in my screenshot) needs to be viewable only after a registered user of a certain access level logs in. What short code or settings do I need to adjust in order to do this? Thanks in advance.
