Blocks of Liquid code are continuously executed via iteration tags. Of the following, which one is NOT an iteration tag?

Answer: while

Liquid, Shopify's templating language, includes iteration tags like `for`, `cycle`, and `tablerow` to loop through collections or perform repetitive tasks. However, `while` loops are not a native construct in Liquid. Liquid is designed for simpler, safer templating logic, and `while` loops, which can potentially lead to infinite loops, are generally excluded from such templating languages.

The ____ tag in Liquid only runs a block of code if a specific condition is not true (that is, if condition is false).

Answer: If

The `if` tag is the fundamental conditional control flow tag in Liquid. While the `unless` tag is specifically designed to run a block of code when a condition is false, the `if` tag can achieve the same outcome by using the `not` operator (e.g., `{% if not condition %}`). This makes `if` the versatile tag capable of handling both true and false conditions, including the scenario described.
