If you'll look again, you'll find that C++ also uses only leading
delimiters,
i.e., "//".
The only advantage to comments delimited on both ends is that you can have
multi-line comments, in such a case.

I have a question...I am learning some programming languages and have
noticed that some languages such as Pascal and C++ use delimiters on both
ends of comments. Other languages, such as Fortran and Ada, use a symbol of
symbols to indicate the beginning of a comment and the end of line to
terminate it. Why would these languages take such different aprouches to
solving the same problem and which method is better?

UCSD Pascal generated a warning when you commented out
a semicolon, quite useful :-)

The reason Ada avoided a comment terminator is so that you can't
accidently comment-out any code.
If you're using Pascal or C, then be sure to use an editor that supports
color-coding. You have to make it obvious which part of your code is
comment, and which is not.

How did one sift through the false negatives, looking for the true
negatives? Or did this simply cause semicolons to be not used within
comments?
