[EX Q]: "Castle" is a wonderful book for children who have short attention spans. It provides adventure and re-affirms the laws of chivalry.
[EX A]: Positive

[EX Q]: This completely predictable novel seems more like a beginner's attempt of writing a book rather than an American classic. The author treats the readers as if they completely lack a brain by stating the understood and by completely beating concepts to death (note the reference).
[EX A]: Negative

[EX Q]: This pack comes with a wide variety of products. It is a great introduction to the Komenuka line. I really enjoyed how clean my skin felt after using the cleanser. The moisturizer is light and not at all greasy. I would recommend this line to anyone.
[EX A]:
Positive
