Which two of the following placements on Pinterest are used to discover ideas?

Pinterest is a visual discovery engine where users actively seek inspiration and ideas. The "Related" placement surfaces content similar to what a user is currently viewing, helping them explore more ideas within a topic. "Search" is a primary discovery tool, allowing users to input keywords and find Pins, boards, and profiles directly related to their interests. Live streams and commercials are not primarily discovery placements; live streams are real-time broadcasts, and commercials are advertisements, neither of which are designed for broad idea exploration in the same way as Related or Search.
