Keet was riding the bus and saw a man wearing a new pair of shoes from his favorite brand. He liked them but thought they'd look better in black. When he got home, he went online and found them in black at an online store, Zaps. They were pretty expensive, so he decided to post a picture of them on his social media account to see what his friends would think. The next day, he started seeing ads for the exact shoes and for the online store he had visited. He saw the ads appear when he typed in a search, when he went to his favorite news site, and when he was scrolling through his social media feed. At first he thought it might've just been a coincidence, but when it kept happening, he started to wonder, why am I seeing this everywhere? 1.How did the advertising company know he was interested in those shoes?
2.Are you OK with using apps or websites that collect and share information about you? Does it matter what information they collect? Or whom it gets shared with? Why, or why not?

not concrete, existing in thought or as an idea but not having a physical or concrete existence

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 !

comfortable

explanation:

one type of the adjectives is predicate adjective. a predicate adjective is an adjective which follows a linking verb and modifies or refers back to the main subject of that linking verb.

it usually is used just before the noun it modies.

here in this example:

'penguins seem comfortable in the coolest habitats', comfortable is the predicate adjective which follows the linking verb 'seem' and modifies the noun.
