Social Media for Strategic Communication Practice Test

Understanding audience reach in a country means looking at how many people actually use the app among that country’s online population. TikTok’s growth in the United States produced a large, credible user base without implying universal adoption. Sixty million reflects a substantial share of users—enough to drive strong engagement and presence in the market—while still staying plausible given the size of the U.S. online audience. The other figures would require much higher penetration than what was typical for the platform’s US footprint at that time, or would be too small to represent the app’s observed momentum. So sixty million is the best fit for the US user base in this context.
