[Q]: (CNN) -- Sevilla have sacked coach Manolo Jimenez after their disappointing home draw to bottom-club Xerez on Tuesday extended the club's winless run to seven games. Despite lying fifth in the Spanish Primera Liga table, Sevilla were knocked out of the lucrative European Champions League by Russian side CSKA Moscow last week. Jimenez had also secured a Copa del Rey final against Atletico Madrid but it wasn't enough to save the 46-year-old's job. The club's sporting director Ramon Rodriguez admitted the decision had been difficult but said he had "done what I had to." He told the club's official Web site: "It was an unavoidable situation and we had to find a solution, and the pain that it brings. "Tuesday was the end of the story but the decision comes from the image and dynamics of the team. Without doubt we are grateful to Manolo. He is an excellent professional, he has made all this possible and impossible. However it is obvious that he could not get a response out of the team. "Fortunately we believe that there is time. The growth and the ambition of the club is shown in the change of the manager. We are fighting for important things." Xerez's injury-time equaliser on Tuesday meant Sevilla's last league success was against Real Mallorca back in February. Ironically, it is Mallorca who occupy the much-coveted fourth spot in the table that guarantees Champions League football next season. Jimenez took charge in October 2007 when former coach Juande Ramos left to take over at English Premier League team Tottenham. <sep>What was Sevilla's last league success, and where does that team now rank in the Champions League football table?<sep>Real Mallorca's Team- 6th
[A]: No


[Q]: Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter. <sep>Can sound waves travel through empty space?<sep>definitely not
[A]: Yes


[Q]: Speed is an important aspect of motion. It is a measure of how fast or slow something moves. To determine speed you must know two things. First, you must know how far something travels. Second, you need to know how long it takes to travel that far. Speed can be calculated using this formula: speed = distance time A familiar example is the speed of a car. In the U.S., this is usually expressed in miles per hour. Think about a trip you and your family made in the car. Maybe the trip covered 120 miles and it took 3 hours. What was the cars speed? speed = 120 mi = 40 mi/h 3h The speed of a car may also be expressed in kilometers per hour (km/h). The SI unit for speed is meters per second (m/s). This is the unit of measure a scientist would use. <sep>How do US speed measurement and those used by a scientist differ?<sep>Scientist use miles
[A]:
No
