Question

I am just going to post office. I won't be long нужно вставить артикль

Answer 1

The post office Артикль "The" 

Answer 2

I am just going to the post office. I won't be long.

In this sentence, the correct article to use is "the" before "post office." The article "the" is used to refer to a specific noun that is known or mentioned before. In this case, the speaker is referring to a specific post office that they are going to, so "the" should be used.

Using the article "a" before "post office" would imply that the speaker is going to any random post office, without specifying which one. However, since the speaker mentions "the" post office, it suggests that there is a particular post office they are referring to, possibly one that is known to both the speaker and the listener.

Therefore, the correct sentence is: "I am just going to the post office. I won't be long."
