Question: Read the article and select the best answer. Article: Another common type of reasoning is the search for causes and results.We want to know whether cigarettes really do cause lung cancer, what causes malnutrition, the decay of cities, or the decay of teeth.We are equally interested in effects: what is the effect of sulphur or lead in the atmosphere, of oil spills and raw sewage in rivers and the sea, of staying up late on the night before an examination? Causal reasoning may go from cause to effect or from effect to cause.Either way, we reason from what we know to what we want to find out.Sometimes we reason from an effect to a cause and then on to another effect.Thus, if we reason that because the lights have gone out, the refrigerator won't work, we first relate the effect (lights out) to the cause (power off) and then relate that cause to another effect (refrigerator not working).This kind of reasoning is called, for short, effect to effect.It is quite common to reason through an extensive chain of causal relations.When the lights go out we might reason in the following causal chain: lights out--power off--refrigerator not working--temperature will rise--milk will sour.In other words, we diagnose a succession of effects from the power failure, each becoming the cause of the next. Causes are classified as necessary, sufficient, or contributory.A necessary cause is one which must be present for the effect to occur, as combustion is necessary to drive a gasoline engine.A sufficient cause is one which can produce an effect unaided, though there may be more than one sufficient cause; a dead battery is enough to keep a car from starting, but faulty spark plugs or an empty gas tank will have the same effect.A contributory cause is one which helps to produce an effect but cannot do so by itself, as running through a red light may help cause an accident, though other factors -- pedestrians or other cars at the crossroads -- must also be present. In establishing or refuting a causal relation it is usually necessary to show the process by which the alleged cause... Question: Your refrigerator is not working and you have found that the electric power has been cut off. The power failure is a _ Options: A: necessary cause B: sufficient cause C: contributory cause D: none of them
Answer: B

Question: Read the article and select the best answer. Article: The easy way out isn't always easiest. I learned that lesson when I decided to treat Doug, my husband of one month, to a special meal. I glanced through my cookbook and chose a menu which included homemade bread. Knowing the bread would take time, I started on it as soon as Doug left for work. As I was not experienced in cooking, I thought if a dozen was good, two dozen would be better, so I doubled everything. As Dong loved oranges, I also opened a can of orange and poured it all into the bowl. Soon there was a sticky dough covered with ugly yellowish marks. realizing I had been defeated, I put the dough in the rubbish bin outside so I wouldn't have to face Doug laughing at my work, I went on preparing the rest of the meal, and, when Doug got home , we sat down to Cornish chicken with rice . He tried to enjoy the meal but seemed disturbed. Twice he got up and went outside, saying he thought he heard a noise. The third time he left, I went to the windows to see what he was doing. Looking out, I saw Doug standing about three feet from the rubbish bin, holding the lid up with a stick and looking into the container. When I came out of the house, he dropped the stick and explained that there was something alive in out rubbish bin . Picking up the stick again, he held the lid up enough for me to see. I felt cold. But I stepped closer and looked harder. Without doubt it was my work. The hot sun had caused the dough to double in size and the fermenting yeast made the surface shake and sigh as though it were breathing. I had to admit what the 'living thing 'was and why it was there. I don't know who was more embarrassed by the whole thing Doug or me. Question: What made the dough in the rubbish bin? Options: A: The rising and falling movement. B: The strange-looking marks. C: Its shape. D: Its size.
Answer: A

Question: Read the article and select the best answer. Article: Three Boys and a Dad Brad closed the door slowly as Sue left home to visit her mother.Expecting a whole day to relax,he was thinking whether to read the newspaper or watch his favourite TV talk show on his first day off in months."This will be like a walk in the park,"he'd told his wife."I'll look after the kids,and you can go visit your mom." Things started well,but just after eight o'clock,his three little "good kids"--Mike,Randy,and Alex--came down the stairs in their night clothes and shouted "breakfast,daddy."When food had not appeared within thirty seconds,Randy began using his spoon on Alex's head as if it were a drum.Alex started to shout loudly in time to the beat .Mike chanted "Where's my toast,where's my toast" in the background.Brad realised his newspaper would have to wait for a few seconds. Life became worse after breakfast.Mike wore Randy's underwear on his head.Randy locked himself in the bathroom,while Alex shouted again because he was going to wet his pants.Nobody could find clean socks,although they were before their very eyes.Someone named "Not Me" had spilled a whole glass of orange juice into the basket of clean clothes.Brad knew the talk show had already started. By ten o'clock,things were out of control.Alex was wondering why the fish in the jar refused his bread and butter.Mike was trying to show off his talent by decorating the kitchen wall with his colour pencils.Randy,thankfully,appeared to be reading quietly in the family room,but closer examination showed that he was eating apple jam straight from the bottle with his hands.Brad realised that the talk show was over and reading would be impossible. At exactly 11:17,Brad called the daycare centre ."I suddenly have to go into work and my wife's away.Can I bring the boys over in a few minutes?"The answer was obviously "yes" because Brad was smiling.(2012*,B) Question: This text is developed _ .
