Which function returns the first five characters of a string?

Explanation:
To get the first five characters, you use the function that returns the leftmost portion of the string when you specify how many characters to take. Left(string, 5) yields the first five characters, for example Left('abcdef', 5) -> 'abcde'. Mid returns a substring starting at a given position, so it’s not inherently anchored to the start. Substring is a general extraction that can start anywhere. Right takes characters from the end, not from the front. So the function that returns the first characters is Left.
