question:
(CNN) -- Britain's Chris Froome won the 17th stage of the Tour de France on Wednesday to strengthen his grip on the yellow jersey. Froome completed Wednesday's 32-kilometer time trial in 51 minutes 33 seconds, nine seconds ahead of Spain's Alberto Contador with his compatriot Joaquim Rodriguez Oliver finishing a further second behind in third. "I couldn't believe it when I got over the line and saw I had the fastest time," Froome said after his third stage win of this year's tour. "I went into today thinking I was going to try and limit my losses, thinking about the days to come now. So to go through the finish line with the fastest time, I really didn't see that coming." On mountainous terrain along a frequently twisting route most of the riders opted for their traditional road bikes over the more aerodynamic machines used in time trials. But Froome opted to use both on the stage, switching to a time trial model for the final 12-kilometer descent. The swap proved decisive as the Briton clawed back a 20-second advantage Contador had built up earlier in the stage. The Spaniard now moves up to second overall, four minutes 34 seconds behind Froome with just four stages remaining. Contador's Saxo-Tinkoff teammate Roman Kreuziger is now third and trails Froome by four minutes and 51 seconds. Thursday sees the riders tackle the gruelling 172.5-kilometer 18th stage which concludes with a double ascent of Alpe d'Huez over the last 60 kilometers. <sep>How long did Fromme bike on the 17th stage before the final descent?<sep>32 kilometers
answer:
No

question:
The day was just breaking, as I left the tower; though it was still too dark in the house to be able to see without a light, and I took one of the study candles with me on my 'round. By the time I had finished the ground floor, the daylight was creeping in, wanly, through the barred windows. My search had shown me nothing fresh. Everything appeared to be in order, and I was on the point of extinguishing my candle, when the thought suggested itself to me to have another glance 'round the cellars. I had not, if I remember rightly, been into them since my hasty search on the evening of the attack. For, perhaps, the half of a minute, I hesitated. I would have been very willing to forego the task--as, indeed, I am inclined to think any man well might--for of all the great, awe-inspiring rooms in this house, the cellars are the hugest and weirdest. Great, gloomy caverns of places, unlit by any ray of daylight. Yet, I would not shirk the work. I felt that to do so would smack of sheer cowardice. Besides, as I reassured myself, the cellars were really the most unlikely places in which to come across anything dangerous; considering that they can be entered, only through a heavy oaken door, the key of which, I carry always on my person. <sep>When did the person consider extinguishing the candle?<sep>Found nothing
answer:
Yes

question:
Once upon a time I had a dog named Toodles. He was black and white and had long floppy ears. He also had very short legs, but really big paws. Every Saturday we would go to the park and play Toodles' favorite game. Toodles loved playing fetch. One Saturday, Toodles ran over to the pond because he saw ducks swimming there. He ran all around the pond, barking at the ducks. The ducks ignored him, and kept swimming. Toodles wasn't having it! He jumped into the pond and started swimming toward the ducks, chasing around his new playmates. One of the ducks, braver than the others, poked Toodles with his beak - and then bit him right on one of his floppy ears! Toodles barked and ran out of the pond because the duck hurt his ear. Soaking wet, he ran toward where I was eating a sandwich on the grass and curled right up in my lap so I could make him feel better. After that, whenever he would see a duck, Toodles would run the other way. <sep>What was the narrator doing when the duck bit Toodles' ear?<sep>He was sitting on the ground eating a sandwitch
