Example Input: Dear potential sucker,My first airbed by intex sprung a leak in about a week, so I obtained a refund. I bought this model next, and it lasted almost twice as long!I am now on my third. I should have learned my lesson, but my current intex airbed has been around for about one year, and currently has 9, count 'em, NINE leaks. Everytime I patch one, another springs.Intex also makes inflateable boats. They must get sued for a lot of drownings. No wonder they have no email contact. If you buy ANY intex airbed, you are buying utter garbage.Sincerely,SidWa State
Example Output: Negative

Example Input: This is nothing new from Gail Howard, or at all. These wheeling systems can be worked out mathematically, without paying for this book. There are also lots of websites that offer number generators and wheeling system explanations for free. If you want it all spelled out for you then buy this book, but if you are willing to do a little mathematical work check out lottery information website like [...].
Example Output: Negative

Example Input: My children (ages 5-10) love this book. I have also read from this book to hospitalized teenagers; when I read Oedipus I finished the story and heard a chorus of "read it again!"I noticed that some of the reviews posted here say that this book is unsuitable for children, but I wonder if the reviewers actually tried reading the book to them.
Example Output:
Positive
