One example: Hopeful for those who seek harmony in the world . I wouldn't recommend this to anyone who thinks that religious wars, repression of individual spirits or rape of the earth are good things. Those who seek peace, harmony, celebration of each of us and respect for  our earth will find this hopeful
Solution is here: POS
Explanation: The overall sentiment of the review is positive as the reviewer mentions positive expressions such as 'hopeful', 'will find this helpful' etc.. Hence, the label is 'POS'.

Now, solve this: Athena and Kain: The True Meaning of Greek Myth . The preface to ATHENA and KAIN states that the content of the book is revolutionary, and it really is. I looked up revolutionary, and in the context used it means, &quot;a total or radical change, as a revolution of thought.&quot; There is no other book on Greek art or myth like ATHENA and KAIN. Mr. Johnson points out that Greek sculptures appeared on public temples and other public buildings, and that mythological scenes appeared on the ancient Greeks' everyday pottery and storage jars. The average Greeks understood the meaning of their myths. Because of ATHENA and KAIN, it is now possible for us to understand them, too
