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. <sep>What can be done to prevent friction problems in engines?<sep>Oil is added to the engine

SOLUTION: Yes

PROBLEM: A married couple and their three young adult children , a son and two daughters , live in a large compound with a garden and a swimming pool .  A tall fence surrounds the property and the children have never been on the other side of it , for their parents have kept them unaware of the outside world , even of the existence of the telephone .  They are taught different meanings for everyday words .  For example , they are told that a `` zombie '' is `` a small yellow flower , '' and that `` sea '' is a chair .  The parents promise that each child will be ready to venture outside the compound once she or he has lost a dogtooth .  Although the children are told they have a brother just on the other side of the barrier , he never appears .  The only non-family member to come into the house is Christina , a young woman who works as a security guard at the father's factory .  She is driven by the father to the compound traveling both ways blindfolded where she performs sexual favors for the son .  Dissatisfied with his preference for intercourse , Christina seeks oral sex from the elder daughter in exchange for a headband.  The elder daughter obliges but does not recognize the significance of performing cunnilingus .  Later , she gives the headband to her younger sister , in exchange for being licked on the shoulder , Which is marked by an unexplained scar .  The parents have tricked the children into believing that overhead planes are merely toys .  They allow the children to search for toy planes that they have planted on the grounds , and the child that finds the toy owns it . <sep>How many people does the headband belong to over the course of the story?<sep>Three

SOLUTION: Yes

PROBLEM:  But I think it is certain that most of the early Christians understood these words of our Lord's ascension and coming again in glory.  They believed that He was coming again in a very little while during their own life-time, in a few months or years, to make an end of the world and to judge the quick and the dead.  And as they waited for His coming, one generation after another, and yet He did not come, a sadness fell upon them.  Christ seemed to have left the world.  The little while that He had promised to be away seemed to have become a very long while.  Hundreds of years passed, and yet Christ did not come in glory.  And, as I said, a sadness fell on all the Church.  Surely, they said, this is the time of which Christ said we were to weep and lament till we saw Him again--this is the time of which He said that the bridegroom should be taken from us, and we should fast in those days.  And they did fast, and weep, and lament; and their religion became a very sad and melancholy one--most sad in those who were most holy, and loved their Lord best, and longed most for His coming in glory. <sep>Who believed their Lord was coming again in a very little while during their own life-time?<sep>Christians

Yes
