Input: Consider Input: Another excellent book by this author. It's not morbid or icky-just states the facts. Great for young readers (I wouldn't go below 13 though, just because it's not ...oh...easy to read? Not because of subject matter, but because it is written in an adult voice...she doesn't dumb it down.) I am planning to buy several more for Christmas gifts.

Output: 5

Input: Consider Input: If you have narrow to medium feet, these might work for you. If you have medium to wide, you may not ever get them on. The knit is not stretchable like it looks in the picture. One good thing, once they are actually on, there is plenty of room in the toes, unlike most shoes. Wish I could stretch out the weave. The seller was very accommodating and gave me a refund. Good customer service.

Output: 3

Input: Consider Input: I loved on how the writer explains everything in sequence, even if it some parts were way too technical and are not for everyone to comprehend. Found a lot of interesting/previously-unknown facts and felt that I actually got something out of the book.
Output: 4
