Input: (CNN) -- Jo-Wilfried Tsonga ended Roger Federer's hopes of winning a record-equaling seventh Wimbledon title on Wednesday as the French 12th seed staged a stunning fightback to reach the semifinals. Federer appeared to be cruising into the last four after winning the first two sets, but Tsonga inflicted the Swiss world No. 3's first defeat from that vantage point in 179 grand slam matches. It was only the third time in the 29-year-old's glittering career that the 16-time grand slam champion had surrendered a two-set lead. Tsonga, ranked 19th in the world, triumphed 3-6 6-7 (3-7) 6-4 6-4 6-4 on Centre Court, serving out to love as he earned a clash with second seed Novak Djokovic. The Serbian, who beat Tsonga in the 2008 Australian Open final, ended the dream run of Australian 18-year-old Bernard Tomic. Tsonga defeated Federer for just the second time in six meetings, their first on grass. "It was amazing. I played unbelievable. It's never easy to come back against Roger. I'm so happy, it's crazy," the 26-year-old told reporters after reaching the semifinals at Wimbledon for the first time. "He's the biggest champion in the sport. He has achieved so much and is the best player in the world. To be two sets down and come back was unbelievable. I served really well. Against Djokovic I will have to come out and do the same again." Federer has now lost in the quarterfinals two years in a row, being beaten by eventual runner-up Tomas Berdych in 2010. "Jo played great. Really from start to finish I don't remember seeing a break point after I broke him in the first game," Federer said.

Does the response "The passage doesn't mention a two-set lead" correctly answer the question "The defeat of Federer by Tsonga was the first loss from a two-set lead in how many grand slam matches, and how many times has Roger Federer lost from this same vantage point?"?

Input: Alexander's body was laid in a gold anthropoid sarcophagus that was filled with honey, which was in turn placed in a gold casket. According to Aelian, a seer called Aristander foretold that the land where Alexander was laid to rest "would be happy and unvanquishable forever". Perhaps more likely, the successors may have seen possession of the body as a symbol of legitimacy, since burying the prior king was a royal prerogative. While Alexander's funeral cortege was on its way to Macedon, Ptolemy seized it and took it temporarily to Memphis. His successor, Ptolemy II Philadelphus, transferred the sarcophagus to Alexandria, where it remained until at least late Antiquity. Ptolemy IX Lathyros, one of Ptolemy's final successors, replaced Alexander's sarcophagus with a glass one so he could convert the original to coinage. The recent discovery of an enormous tomb in northern Greece, at Amphipolis, dating from the time of Alexander the Great has given rise to speculation that its original intent was to be the burial place of Alexander. This would fit with the intended destination of Alexander's funeral cortege. Pompey, Julius Caesar and Augustus all visited the tomb in Alexandria, where Augustus, allegedly, accidentally knocked the nose off. Caligula was said to have taken Alexander's breastplate from the tomb for his own use. Around AD 200, Emperor Septimius Severus closed Alexander's tomb to the public. His son and successor, Caracalla, a great admirer, visited the tomb during his own reign. After this, details on the fate of the tomb are hazy. The so-called "Alexander Sarcophagus", discovered near Sidon and now in the Istanbul Archaeology Museum, is so named not because it was thought to have contained Alexander's remains, but because its bas-reliefs depict Alexander and his companions fighting the Persians and hunting. It was originally thought to have been the sarcophagus of Abdalonymus (died 311 BC), the king of Sidon appointed by Alexander immediately following the battle of Issus in 331. However, more recently, it has been suggested that it may date from earlier than Abdalonymus' death.

Does the response "The location of Alexander's remains is unknown" correctly answer the question "Where are Alexander's remains?"?

Input: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.
