Where do prefixes occur in a word?
after a word
* at the beginning of a word
in the middle of a word
at the end of a word

The correct answer is B. At the beginning of a word

Explanation:

In grammar, a prefix refers to a letter, set of letters or syllable that works as an affix and is placed before or a the beginning of a root word or basic unit. This type of affixes differs from suffixes because suffixes are always placed at the end of words and not at the beginning of them. Examples of common prefixes include "un-" that means not as in the word "uncover", "pre" that means before as in the word "pre-existing" or the prefix "co-" that means with as in the word "cooperation". Considering this, it can be concluded prefixes always occur at the beginning of a word.

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 !
