Answer: A book analyzing The Communist Manifesto is a secondary source.
Step-by-step explanation:
A secondary source is a piece of information or an interpretation of a primary source that was created after the primary source. A primary source is a piece of information or an interpretation that was created by an individual or group who witnessed or participated in the event or phenomenon being studied.
In this case, "an autobiography by Mark Twain" and "the scientific journal of Louis Pasteur" and "a transcript of a speech by Franklin D. Roosevelt" are all primary sources, as they are original works created by individuals who witnessed or participated in the events or phenomena being studied.
On the other hand, "a book analyzing The Communist Manifesto" is a secondary source, as it is an interpretation or analysis of the primary source "The Communist Manifesto" which was written by Karl Marx and Friedrich Engels. This secondary source is created by an author who did not participate in the events or phenomena being studied, but instead is interpreting and analyzing the primary source document.
