[EX Q]: Paragraph- Sent 1: You know that friction also causes heat.
Sent 2: Think about when you rub your hands together.
Sent 3: It is friction that makes them warm.
Sent 4: But why does this happen?
Sent 5: Friction causes the molecules on rubbing surfaces to move faster.
Sent 6: Faster moving particles have more heat energy.
Sent 7: Heat from friction can be useful.
Sent 8: Can you think of other places where you might find friction?
Sent 9: Friction also lets you light a match.
Sent 10: Heat from friction can also cause problems.
Sent 11: It can cause a car to overheat.
Sent 12: To reduce friction, oil is added to the engine.
Sent 13: Oil coats the surfaces of moving parts.
Sent 14: This coating of oil makes them slippery.
Sent 15: When things are slippery there is less friction.
Sent 16: Have you ever seen a sign that says, slippery when wet?
Sent 17: This too has to do with friction.
Sent 18: Water, like oil, can reduce friction.
Sent 19: The wet surface may allow your shoes to slide more easily. 
Question: What would happen if all the oil leaked out of a running car engine?.
[EX A]: It would overheat.

[EX Q]: Paragraph- Sent 1: Madrid, Spain (CNN) -- Relatives of a woman killed in a Spanish airline crash were erroneously given the remains of another victim, and then were asked by authorities to return them, CNN partner network CNN+ reported Thursday.
Sent 2: The victims of the crash were first laid out at a Madria convention center.
Sent 3: A Madrid judge has opened an investigation into the error, and judicial sources say the initial indication is that the mixup occurred not in the proper identification of the victim, but in delivering the wrong remains to the family in question, CNN+ reported.
Sent 4: The family Wednesday received an urn numbered 104, and were told it contained the ashes of their loved one, Pilar Gonzalez Ferreira, who died in the crash.
Sent 5: But as the family was preparing to leave Madrid, officials called to tell them about the error and asked for the return of urn 104, CNN+ reported.
Sent 6: Instead of urn 104, the family was supposed to have received urn 134, which actually contains the remains of Pilar Gonzalez, CNN+ reported, citing judicial sources and another family which also lost a relative in the crash.
Sent 7: The Spanair MD82 jet crashed last week at Madrid's airport as the plane was trying to take off, killing 154 people.

Sent 9: Then the out-of-control plane skidded and bounced at least three times as it careered 1,200 meters (3,840 feet) across uneven terrain and exploded, coming to rest in a gully, a top official of the investigative commission told a news conference in Madrid on Tuesday.
Sent 10: Many of the bodies were badly charred from the fire, and authorities have used DNA samples to carry out numerous identifications. 
Question: Where all the remains returned correctly to the famalies?.
[EX A]: No, the remains of Pilar Gonzalez Ferreira were initially not correctly returned to the family. The remains were correctly identified, but due to a delivery error the family received the wrong Urn, No 104, instead of 134.

Sent 4: During a partial lunar eclipse, only a portion of the Moon enters Earths umbra.
Sent 5: When the Moon passes through Earths penumbra, it is a penumbral eclipse.
Sent 6: Since Earths shadow is large, a lunar eclipse lasts for hours.
Sent 7: Anyone with a view of the Moon can see a lunar eclipse.
Sent 8: So unlike a solar eclipse, it doesnt get dark on Earth.
Sent 9: Instead it gets dark on the Moon.
