QUES: The one person who, by his interference, could have settled all doubts was debarred by circumstances from interfering in the matter. Wykham Delandre had quarrelled with his sister--or perhaps it was that she had quarrelled with him--and they were on terms not merely of armed neutrality but of bitter hatred. The quarrel had been antecedent to Margaret going to Brent's Rock. She and Wykham had almost come to blows. There had certainly been threats on one side and on the other; and in the end Wykham, overcome with passion, had ordered his sister to leave his house. She had risen straightway, and, without waiting to pack up even her own personal belongings, had walked out of the house. On the threshold she had paused for a moment to hurl a bitter threat at Wykham that he would rue in shame and despair to the last hour of his life his act of that day. Some weeks had since passed; and it was understood in the neighbourhood that Margaret had gone to London, when she suddenly appeared driving out with Geoffrey Brent, and the entire neighbourhood knew before nightfall that she had taken up her abode at the Rock. It was no subject of surprise that Brent had come back unexpectedly, for such was his usual custom. Even his own servants never knew when to expect him, for there was a private door, of which he alone had the key, by which he sometimes entered without anyone in the house being aware of his coming. This was his usual method of appearing after a long absence.

QUES: Jenny was a 13 year old girl with blond hair and blue eyes. She had gotten out of her last day of school and was free for the summer. Two of her friends were going to the nearby beach to do some swimming and enjoy the sun. Jenny went with them and when they got there the beach was very full and there were people everywhere. They changed into their bathing suits and went to the water. The water was very cold. They chose not swim and walked to the sand. Then they laid down on some towels and enjoyed the sun. After several hours Jenny and her friends fell asleep. They woke up and the sun was beginning to set. When Jenny sat up she found that it was painful to touch her skin. When she looked down she saw that she had a very bad sunburn. Her friends were also very badly sunburned so they went home. Jenny's mother gave her a cream to put on the sunburn. Afterwards she felt a lot better and went to sleep.

QUES: Shelly wanted a puppy. She asked her mommy and daddy every day for one. She told them that she would help take care of the puppy, if she could have one. Her mommy and daddy talked it over and said that they would get Shelly a new puppy. Her mommy took her to the dog pound so that she could choose one that she wanted. All the puppies at the dog pound need a loving home. Shelly went to every cage and looked each puppy in the eyes and talked to each one. After each one, she told her mommy, "No, this isn't the one for me." Finally, she saw a black and white spotted one that she fell in love with. She screamed, "Mommy, this is the one!" Her mommy asked the worker to take the puppy out so that Shelly could make sure. Shelly and the puppy fell in love with each other right away. Shelly and her mommy took the black and white spotted puppy home with them. Shelly was so excited that she talked all the way home. After thinking hard, Shelly had a name for her new puppy, Spot. Now, Shelly has a new best friend and they play together every day when Shelly gets home from school.

QUES: 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.
