I'm Brazilian, my homework it's easy for you... <3
Someone answers...

I cleaned the house.

Dad did the shopping.

Mrs. Brown ironed the clothes.

Susan spoke to her colleague.

My neighbour did the gardening.

Our math teacher did not read our tests yet.

The basketball match is not finished yet.

My brother broke a window.

Mr. White hasn't read the newspaper yet

Explanation:

I'm not really sure about the math teacher one lol

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 !
