Which question can you ask yourself if you are making a category inference? O A. How did this happen? B. Why did she do that? C. What is the solution? D. What do all these details have in common?​

the answer is How did this happen

a main idea dna proper infromation

there is 2 main differences, basically which are the users and the market. the other difference is the kind of content

people who use tik tok are mainly people from east asia, kind of like the app douyin. musically, on the other hand, are used by people from america or european countries.

while tik tok videos show things like daily life videos, comedy, or just funny videos, musically are like people mimicking songs with their own actions, 'imitate' singers and video clips.

hope this !
