What is the meaning of selecting extension content and developing appropriate content?

Selecting extension content refers to the process of choosing or picking out specific materials or resources that will be used to enhance or expand upon a particular subject or topic. This can include articles, books, videos, or any other form of content that provides additional information or further explores the subject matter.

Developing appropriate content, on the other hand, involves creating or producing content that is suitable, relevant, and tailored to a specific audience or purpose. This can include writing articles, designing presentations, producing videos, or any other form of content that effectively communicates information and meets the needs of the intended audience.

In summary, selecting extension content involves choosing existing materials to supplement a topic, while developing appropriate content involves creating new materials that are suitable for a specific purpose or audience.
