👉 Fill-in-the-blank (FIB) is a type of interactive question or exercise where a user is presented with a sentence or context and must select the correct word or phrase to fill in a blank space. This technique is commonly used in educational settings, language learning apps, and quizzes to test comprehension, vocabulary, and grammar skills. The goal is to engage users actively by requiring them to think critically about the context and choose the most appropriate word, enhancing their understanding and retention of the material.
