What are two commonly used programs in Google Merchant Center? Choose two.

In the context of Google Merchant Center, the programs Product Ratings and Promotions are two central add-on features used to enhance the visibility and credibility of Shopping ads. Product Ratings is a program that allows you to display aggregated star ratings and reviews for specific items, helping shoppers make informed decisions and increasing click-through rates by showcasing product quality. Promotions (also known as Merchant Promotions) allows retailers to highlight special offers—such as "15% off," "Buy one get one free," or "Free shipping"—directly on their product listings with a "special offer" link. While Store Ratings (often called Seller Ratings) and local inventory features are also important, Product Ratings and Promotions are specifically categorized as core Merchant Center programs that advertisers must often manually enable as add-ons to drive higher engagement and conversions from their product feeds.
