People primarily access social networks for information and entertainment, as well as to connect to others and: A. gather and organize their ideas. B. contribute or create something. C. become media consumers. D. earn better grades at school.

The best answer is: **B. contribute or create something.** **Explanation:** While people use social networks to access information and entertainment and to connect with others, a significant primary reason is to **contribute or create content**. Users actively post updates, share photos and videos, create groups, and engage in various forms of content creation and sharing. This active participation distinguishes social networks from merely being platforms for passive consumption of media. **Option Breakdown:** - **A. gather and organize their ideas.** While some users may use social networks for this purpose, it's not as universally primary as content creation. - **B. contribute or create something.** This is a central activity on social networks, making it the most fitting choice. - **C. become media consumers.** Social networks do serve as media consumption platforms, but they equally emphasize user-generated content. - **D. earn better grades at school.** This is generally not a primary reason people use social networks.
