A line segment is a part of a line that usually has two end points (like dots) at the end of each side, or can just be shown as a part of a line. Unlike a line, line segments don't go on for forever and ever! (Lines will usually be shown with two arrows on both sides, instead of two endpoints.)

The opinions and prejudice of an author in writing.
I believe that those two elements greatly affect bias in history because we can never be 100% sure of everything that (may have) happened in history (especially farther in the past), so opinion can affect a historian's writings. Also, everyone is prone to some sort of prejudice, so this can also affect history.
