Positive examples:
input: review: I had a smaller headset that went on the ear. After a 8 - 10 hour workday, my ears were throbbing red and painfully sore. With this headset, I can go the same shift and not feel any pain on my ear. They may feel a little on the heavy side, but if you adjust the head phone cups just right and stretch them, you will not have any problems.Quality and sound, words cannot explain. Its so clear and loud, the headset holds in the sound. When I am on a call or listening to music, I do not hear nothing else, but what's coming in through the headset.
question: Does the headset block sounds from outside?
output: I do not hear nothing else, but what's coming in through the headset.
explanation: The question asks about whether the headset lets outside noises come through, and the output marks the shortest span of the review that completely answers the question.; input: review: This book, besides being a page turner has a lot of food for thought. Story is thrilling and I can guarantee you that it will catch you by surprise. Inferno educated me and made me think about life and decisions. Great book. Highly recommend it. I can't wait for my husband to finish reading it so I can discuss it with someone.
question: How exciting is the story of the book?
output: Story is thrilling and I can guarantee you that it will catch you by surprise.
explanation: The question asks how exciting the story of the book is, and the sentence in the output gives an answer to that. Note that the describing words may not always be the same, but synonyms.; input: review: This is one of those cereals that isn't just for breakfast. Generally it can be very filling and the flavor is excellent. The fruit really is an added bonus. Milk doesn't make this a soggy cereal. The crunchiness is nice to have as I really enjoy the texture. I think this cereal would be excellent any time of day you need that extra pick me up. The fact it's all natural makes it that much better. Although the boxes are smaller than the standard cereal aisle selections one box should last an individual about a week. Overall this has become one of my favorite cereals that doesn't need anything to be excellent.
question: How long does a box of this cereal last?
output: about a week.
explanation: The selected span is a correct answer to the question, although the whole sentence containing it would be a correct answer too.; input: review: My friend and I both ordered the Siam Noodles based on the waitresses' recommendation. I had the veggie version while she got hers with chicken. We were extremely happy with our choice. The sauce was a peanut and coconut milk combination straight from heaven. The dish was the perfect amount of spicy. My friend wasn't too excited by the chicken but the sauce was too yummy to complain about. We topped the meal off with the mango and sticky rice which was absolutely divine. However, the evening took a turn for the crappy when they started cleaning up the restaurant and putting chairs up on tables around as as we were still eating out meal. We weren't notified that the restaurant was closed and the staff was quite rude about the whole thing. I would still go back as the food was great but I wouldn't go there to have a nice long meal. Maybe even do takeout to avoid the rude staff.
question: How did the employees of the restaurant behave?
output: the staff was quite rude about the whole thing.
explanation: Again, you can see here that the answer of the question may not share any words with the question and still be the correct answer.

Negative examples:
input: review: Food was very tasty but the bathrooms were kinda gross. I wouldn't go out of my way to eat here again. It was satisfactory but nothing special.
question: How were the bathrooms?
output: Food was very tasty
explanation: Although the output is a part of the review, it is irrelevant to the question.; input: review: My family stayed at the Hotel Rex while visiting my sister in San Francisco. It's a charming hotel with a great staff. Our room was large and very quiet. The decor is fun, old-fashioned and trendy all at the same time. Breakfast in Cafe Andree downstairs was tasty and the service was fast. Great location, convenient to Union Square and whatever city amenities you need. Valet parking was responsive to whenever we needed our car. Best of all was the pug dog Max, who lounged on one of the chairs in the reception area while his owner worked the desk. I would highly recommend this hotel to anyone who wants to stay in the center of downtown without being in a large corporate-type hotel.
question: How was the room?
output: large and
explanation: Your answer should be a meaningful and complete phrase. In this case, 'large and very quiet' would be the correct answer.; input: review: This was one of the best thriller/psychological suspense/family saga/mystery I have ever read. Ms Flynn has a terrific ability for description and development of very interesting characters.  She puts you right there in the middle of the story. I couldn't put it down.  It has twists and turns and a double ending. As much as I enjoyed this book, there was much dark and depressing elements of the story that I cannot forget.  I'll wait awhile before I read Dark Places, the only other novel I have left to read that she has written. It's not that I don't want to read it. I just want go save it and let the novel just finished digest a bit.  Actually looking forward to Dark Places. Hoping she will have another novel published soon. She is one writer that I intend to keep reading. I did read Gone Girl last year and loved it. But somehow it did not have the same kind of experience for me. It was a great novel but very different . Highly recommend this if you like real psychological thrillers. And some parts require a strong stomach. But so filled with dysfunction and disordered lives that are wonderfully written, no matter how difficult it may be to read. It is a unique kind of book. Not for children and adolescents in my opinion. Some very heavy material and necessary but ugly descriptions of things better left for mature adults. It all comes together and leaves you breathless.
question: Who is a proper audience of this book?
output: children and adolescents
explanation: The given output is a part of the answer, but is clearly wrong. You should be wary when choosing a part of the whole answer span, as it may totally flip the meaning.; input: review: The keyboard fits well for my hands and my wrists receive less pressure using it. The mouse is stable and comfortable to use for big hands. Recommend.
question: How comfortable is the mouse?
output: It is very comfortable.
explanation: Your output should match a span of the given text, do not use your own words, even if they answer the question correctly.
