(Question)
I recently read about a wonderful act of kindness. It is about the country singer, Jan Howard, and it happened in the mid 1950s. You can read about it in her autobiography , Sunshine and Shadow. She suffered a lot with her three children, two of whom were babies. She was forced to leave her husband because he didn't care about the family. At one point she suffered a nervous breakdown due to his cruel and uncaring behavior.      She took her children with her and decided to leave their home, but didn't know her destination. This all took place in a small town in Kansas, called Frontenac. She had very little gas in the tank and no money at all and she didn't even manage to make it out of Frontenac. As she used up the gas she got into a panic . She then went to a house, not knowing the owner. She "put her pride in her pocket" and went to the door.       After she explained her situation to an old lady who answered the door, the lady asked her husband to help Jan carry the children into the house. These kind people allowed her to stay for two weeks until she received some money in the mail from a  . They fed and cared for Jan and her children. This is one of the most exciting acts of kindness I have ever come across in my fifty years. These angels were named Henry and Sarah and they would always be warmly remembered by me for what they did for Jan and her children. What happened to Jan Howard in Frontenac? A) She found a friendly couple as she had expected. B) She didn't have enough money to go on with her journey. C) She couldn't live with her children. D) She suffered a lot because her husband left her.

Ques: Many people have long dreamed of being able to fly around as simply as riding a bicycle.  Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available very soon. Grant Stapleton from Malloy Aeronautics says the Hoverbike, which is able to get in and out of small spaces very quickly, will be a truly personal flying vehicle.  "It can be moved across continents very quickly because it can be folded and packed," he adds. Mr. Stapleton says safety was the company's main concern when developing the Hoverbike. He ays the designers solved the safety issue by using overlapping rotors     to power the vehicle.  The company is testing both a one-third size model and a full-size prototype     of the Hoverbike. Inventors say their Hoverbike will most likely be used first by the police and emergency rescue teams. In New Zealand,  the Martin Aircraft Company is also testing a full-size prototype of its personal flying bike, called Jetpack. It can fly for more than 30 minutes, up t0 1,000 meters high and reach a speed of 74 kilometers per hour. Peter Coker is the CEO of Martin Aircraft Company.  He said Jetpack "is built around safety from the start, " In his words, "reliability is the most important part of it.  We have safety built into the actual structure itself, very similar to a Formula One racing car. " Jetpack uses a gasoline-powered engine that produces two powerful jet streams.  Mr. Coker says it also has a parachute   that can be used should there be an emergency. "It opens at a very low altitude and actually saves both the aircraft and the pilot in an emergency," he adds. What make(s) flying vehicles seem practical now? A) Modem technology. B) New safety rules. C) Love of cycling. D) Public concerns.
Ans: A


Ques:Some futurologists have assumed that the vast upsurge  of women in the workforce may mean a rejection of marriage. Many women, according to this hypothesis, would rather work than marry. The converse  of this concern is that becoming a multi-paycheck household could encourage marriage. In the past, only the earnings and financial prospects of the man counted in the marriage decision. Now, however, the earning ability of a woman can make her more attractive as a marriage partner. Data show that economic downturns tend to put off marriage because the parties cannot afford to establish a family or are concerned about rainy days ahead. As the economy comes to life, the number of marriages also rises. The increase in divorce rates follows to the increase in women working outside the home. Yet, it may be wrong to jump to any simple cause-and-effect conclusions. The impact of a wife's work on divorce is no less cloudy than its impact on marriage decisions. The realization that she can be a good provider may increase the chances that a working wife will choose divorce over an unsatisfactory marriage. But the reverse is equally plausible . Tensions grounded in financial problems often play a key role in ending a marriage. By raising a family's standard of living, a working wife may strengthen her family's financial and emotional stability. Psychological factors also should be considered. For example, a wife blocked from a career outside the home may feel caged in the house. She may view her only choice as seeking a divorce. On the other hand, if she can find fulfillment through work outside the home, work and marriage can go together to create a stronger and more stable union. Also, a major part of women's inequality in marriage has been due to the fact that, in most cases, men have remained the main breadwinners. A working wife may rob a husband of being the master of the house. Depending upon how the couple reacts to these new conditions, it could create a stronger equal partnership or it could create new insecurities. It is said in the passage that when the economy falls  _ A) men would choose working women as their marriage partners B) more women would get married to seek financial security C) even working women would worry about their marriages D) more people would prefer to remain single for the time being
