Problem: 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.

Question: "What can be done to prevent friction problems in engines?"

Answer: "Water is added to the engine"

Question:
(CNN) -- Tito Joseph "TJ" Jackson, who on Wednesday was named temporary guardian of Michael Jackson's three children, was inspired by his famous uncle to form a singing group with his brothers. TJ had been placed in charge of the children when the kids' grandmother, Katherine, left home on July 15 and will watch the children while the legal proceedings play out in a California court. TJ Jackson, 34, is the son of Tito Jackson and the late Delores Martes Jackson. TJ and his older brothers, Taj and Taryll, form the R&B group 3T. Jackson is married with three children, a boy and two girls. Judge suspends Katherine Jackson as guardian of Michael Jackson's children A 1995 article in People described the brothers' childhood as normal despite their famous father, uncle and aunts. Taj Jackson told the magazine: "My mom made sure that we had a real childhood, with birthday parties, baseball, family outings, all that stuff." They were close to their Uncle Michael. "He's like a third parent to us," Taj told People in 1995. Eventually the brothers went along on one of his tours and decided to form a singing group and were recording their first album in 1994 at the time of their mother's death. Initially it was believed Delores Martes Jackson, who had divorced from Tito Jackson in 1993, drowned in a swimming pool, but the case was reopened, and her sons in 1995 filed a wrongful-death lawsuit against a man they accused of killing her. Three years later, Donald Bohana was convicted of second-degree murder and sentenced to 15 years to life in prison, according to People magazine. After reading the above, is "2; Taj Jackson" the correct answer to the question "How many children does Michael Jackson have and who was their temporary guardian?"? OPTIONS:
- no
- yes

Input: Brad, Texas (CNN) -- Authorities were working on plans Friday for residents who were forced to flee a wildfire in northern Texas to return home, a day after firefighters made progress battling the blaze that destroyed dozens of homes. The blaze in Palo Pinto County scorched 6,200 acres by Thursday, according to the Texas Forest Service. The fire is burning near the resort of Possum Kingdom Lake, near the town of Brad, about 100 miles west of Dallas. "We feel much better about this fire today," as the blaze is now 50% contained, said John Nichols, a spokesman for the Forest Service. He said evacuations were lifted for some residents forced to evacuate the fire, which was driven by high temperatures and dry winds. The wildfire has destroyed 40 homes and nine RVs since it began Tuesday, the Forest Service said Thursday. Firefighters were receiving support from aerial tankers and helicopters. Authorities are mapping out plans to allow residents to return to their homes, said Palo Pinto County Sheriff Ira Mercer. Authorities also are trying to open the lake for the Labor Day holiday, he said. On Wednesday, evacuations were ordered in several communities on the north side of the lake after the fire charged over a ridge and approached a dam on the lake, CNN affiliate WFAA reported. The wildfire was moving so fast that the Forest Service pulled out of its command observation post, telling journalists and onlookers to get out of the way of the fire. "My house is right through here, though it may be gone," Tom Hardeston told WFAA as he watched the fire. Nearby ranchers battled to save their herds from the encroaching fire. "I'm just moving them from pasture to pasture," Cindi McCoy told WFAA, referring to her livestock. "As one pasture burns, I'm moving them back to that one and bring(ing) them back around."

Input: Some of the most unusual effects of Hellenization can be seen in Afghanistan and India, in the region of the relatively late-arising Greco-Bactrian Kingdom (250 BC-125 BC) in modern Afghanistan, Pakistan, and Tajikistan and the Greco-Indian Kingdom (180 BC - 10 CE) in modern Afghanistan and India. There on the newly formed Silk Road Greek culture apparently hybridized with Indian, and especially Buddhist culture. The resulting syncretism known as Greco-Buddhism heavily influenced the development of Buddhism and created a culture of Greco-Buddhist art. These Greco-Buddhist kingdoms sent some of the first Buddhist missionaries to China, Sri Lanka, and the Mediterranean (Greco-Buddhist monasticism). The first figural portrayals of the Buddha, previously avoided by Buddhists, appeared at this time; they were modeled on Greek statues of Apollo. Several Buddhist traditions may have been influenced by the ancient Greek religion: the concept of Boddhisatvas is reminiscent of Greek divine heroes, and some Mahayana ceremonial practices (burning incense, gifts of flowers, and food placed on altars) are similar to those practiced by the ancient Greeks. One Greek king, Menander I, probably became Buddhist, and was immortalized in Buddhist literature as 'Milinda'. The process of Hellenization extended to the sciences, where ideas from Greek astronomy filtered eastward and had profoundly influenced Indian astronomy by the early centuries AD. For example, Greek astronomical instruments dating to the 3rd century BC were found in the Greco-Bactrian city of Ai Khanoum in modern-day Afghanistan while the Greek concept of a spherical earth surrounded by the spheres of planets was adopted in India and eventually supplanted the long-standing Indian cosmological belief of a flat and circular earth. The Yavanajataka and Paulisa Siddhanta texts in particular show Greek influence.
"What evidence exists that Greco-Bactrian influence extended to the sciences?" is "Construction of the Silk Road"?
