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
Example solution: POS

Problem: 5 stars are not enough! . This is surely one of the greatest collections of 'linked short-stories' ever written -- it matches Calvino's COSMICOMICS and Borges' LABYRINTHS. Lem is a total genius. A writer of playful little fables that are also philosophically profound (and logically consistent). This book is a brilliant companion to Lem's THE CYBERIAD, with which it shares many themes and ideas. Lem has a beautiful style: he can make engineering terms sound poetic. His rigorously modern metaphors are as original as those of J.G. Ballard, but more varied and lyrical. For Lem, the Periodic Table is an unwritten poem. This book is the final and true ode, and each line is a fantastic, fabulous, incredible story. I give this book 200,000,000 stars. And that's only because I'm not feeling so generous today. It probably deserves A GOOGOLPLEX (1 to the power of 100 raised to the power of 1 to the power of 100) of stars. At least
Solution: POS
