Question: Although in 1947 we were still very new to the atomic age,  we knew about mushroom clouds. A huge crack spread across the library wall upstairs, sending teachers and students screaming down the hall. Had a new world war started? Pale-faced, our young science teacher quickly organized us for a fire drill. We huddled in little groups on the beach side of the school grounds and watched the spreading cloud darken the bright spring sky. Rumors flew every which way, although two hours would pass before we got the full story.One rumor we heard was that the Texas City Monsanto Chemical plant had blown up; children whose parents worked there began to weep. I froze--that was where my father was working that day. The school bell called us back inside, and we were dismissed to find our way home the best way we could. I-d walked a quarter of the three-mile trip to my home when a car horn startled me to attention. My Uncle Barney pulled up alongside me in his old Ford. The instant I saw him, I knew my father was gone. Otherwise, Papa would have come for me himself. As if in slow motion from a great distance, Uncle Barney motioned for me to get in. Numb with grief,  I crawled into the back seat.  I barely took notice of the man sitting there, and didn't recognize him until he reached for me.  When Papa put his strong arms around me, I forgot for a moment that Cherokees  aren't supposed to cry. Many of my fellow students lost their parents in the explosion.  Tragedy would one day come to our family, as it inevitably comes to all, but on the day Texas City blew up, it miraculously passed us by. Because he lost his keys on that April morning, as he explained, my father lived for another 32 years-we were to have a second lifetime forever. What does the author intend to tell us? A) Be prepared for the worst. B) Be brave in disasters. C) Cherish everything that you have. D) Parents are the most important people.

Question: It all starts with a tree.In fact, it starts with several trees.Since the first modern guitars were made in northern Spain over 150 years ago, crafts persons have known the wood to be used is important in making a guitar. Every guitar is made of several different kinds of wood.Each piece is carefully chosen and then cut to fit the part of the guitar for which it is designed.The most important part of a guitar is the soundboard--the piece of wood with a large hole that lies under the strings(,).Guitar makers are careful to make the soundboard just the right shape and thickness.Then they fix stripes of wood across the inside in a special pattern, which helps strengthen the soundboard and improves the tone of the guitar. Wood for the curvy   sides of the guitar must be soaked   in water and bent over a hot iron pipe.When all the pieces of the guitar are ready, they are carefully stuck together with glue .Special woodworking tools are used to shape and smooth the neck of the guitar.The craftsperson must make sure that the neck is perfectly centered over the soundboard. Then it is time to use varnish .This brings out the beauty of the wood.Varnish also improves the sound of the guitar but too much varnish makes the guitar sound flat and dull. Finally guitar strings are attached and tightened to make just the right musical tones.Then it's time to play a song. In order to make the soundboard strong,_. A) people tie strings to the top of it B) stripes are stuck across the inside of wood C) a large hole is made in it D) several pieces of wood are glued together
