whats the paragraph
Explanation:
I will answer you for brainliest, but I need the paragraph in order to answer
Answer: Because
Explanation: Because is the only word that fits here and is gramatically correct in the first place, neverminding the fact that it says "Best Completes" <em>Because</em> is the only word that is gramatically correct in this situation.
Answer:
formal
Explanation:
'strict' and 'harsh' are out because business letters are not meant to insult or criticise, but rather to be courteous (polite). 'fancy' is out because business letters do not use unnecessarily flowery language.
as such, that only leaves us with 'formal' which is an appropriate tone for a business letter since it conveys a sense of seriousness.
