The two correct answers about the intended audience are:
1. **They have a basic knowledge of how social media works.**
2. **They are different genders.**
These assumptions can be safely made because the audience is transitioning from an old social media platform, which implies they have some level of familiarity with social media in general. Additionally, social media platforms typically attract users from diverse backgrounds, which suggests that the audience likely includes individuals of different genders. The other assumptions about their age and opinions on the new platform may not be as reliably made without further context.
