Final answer:
Liquid objects cannot be added to the 'Additional scripts' box in Shopify Admin; it is intended for JavaScript, HTML, and CSS for enhancing the checkout process.
Step-by-step explanation:
The statement that liquid objects can be added to the 'Additional scripts' box on the Shopify Admin at 'Settings > Checkout' is false. The 'Additional scripts' box is specifically for adding custom JavaScript, HTML, and CSS that are used to enhance or track the checkout process. Shopify's Liquid objects, on the other hand, are part of a templating language for loading dynamic content and are used within the theme files, not directly in the 'Additional scripts' box. Users need to be cautious when adding code to their checkout as this can significantly affect the functionality and security of the checkout process.
