A representation is 10000 bytes long. Which range specifier requests exactly its last 500 bytes?

الشرح

A leading hyphen forms a suffix-range meaning the last N units, so bytes=-500 covers offsets 9500 through 9999. Byte offsets start at zero and both positions are inclusive, so the equivalent int-range is bytes=9500-, and any specifier ending at 10000 would name an offset past the end.
