To keep a person's first and last name together on the same line so that they always stay together, use the spacebar.

The statement is false because using the spacebar to separate a person's first and last name does not guarantee that they will remain together on the same line in a word processing program like Word. Instead, to ensure that the first name and last name stay together, one should use a non-breaking space or a character that prevents the line from breaking at that point. A non-breaking space is a special type of space that prevents the text it separates from being split into different lines. This technique is particularly useful in situations where the name might otherwise be split at the end of a line, ensuring that they are always displayed together, preserving both readability and the intended format of the name.
