Radha is a student of class IX in a school in Ambala city in Haryana. Radha's father, Mr. Vijat Kumar, is the Deputy Commissioner of Police in Ambala zone. Radha's family including her father, mother and five year old brother Pulkit, were invited for the celebrations of Air Force Day at the Ambala Air Force Base. During these celebrations, the final item was a fly-past by the fighter jet planes of Indian Air Force. Suddenly there was a loud, explosive noise in the sky over the celebration venue. All the eyes turned up towards the sky. Everybody saw the Indian Air Force's fighter jet planes flying at tremendous speed in a special formation. All the people started clapping for this beautiful and daring fly-past by Indian Air Force pilots. The thunderous sound produced by the speeding fighter planes was so loud that all the birds sitting on the nearby trees flew away. Radha's brother Pulkit was already undergoing treatment for some ear ailment. So, Pulkit got too much pain in his ears due to this intolerable explossive sound. Pulkit was carrying two sharpened pencils with him at that time. He tried to put these pencils inside his ears to get relief from severe pain in the ears. Radha snatched the pencils from Pulkit and warned him not to do it again. Radha was carrying some cotton ear buds in her purse. So, she put cotton ear buds into the ears planes thoroughly. Everyone was praising Indian Air Force for putting up a great show. Jai Ho!

(f) Name one object which travels at a speed greater than that of fighter jet plane producing loud burst of sound.

There are two ways in which, 'nonasserters' manage a conflict. Sometimes they ignore their needs. Faced with a constantly barking dog, for instance, a nonassertive person would try to forget the barking by closing the windows and trying to concentrate even harder. Another form of denial would be to claim that no problem exists-that a little barking never bothered anyone. To the degree that it's possible to make problems disappear by ignoring them, such an approach is probably advisable. In many cases, however, it simply isn't realistic to claim that nothing is wrong. For instance, if your health is beingjeopardized by the cigarette smoke from someone nearby, you are clearly punishing yourself by remaining silent. If you need to learn more information from a supervisor before undertaking a project, you reduce the quality ofyourworkby pretending that you understand it at all. If you claim that an unsatisfactory repair job is acceptable, you are paying good money for nothing. In all these and many more cases simply pretending that nothing is the matter when your needs continue to go unmet is clearly not the answer.
A second nonassertive course of action is to acknowledge your needs are not being met but simply to accept the situation, hoping that it might clear up without any action on your part. You could, for instance, wait for the neighbour who owns the barking dog to move. Y ciu could wait for the dog to be run over by passing car or to die of old age. You could hope that your neighbour will realize how noisy the dog is and do something to keep it quiet. Each of these occurrences is a possibility, of course, but it would be unrealistic to count on one of them to solve your problem. And even if by chance you were lucky enough forthe dog problem to solve without taking action, you couldn't expect to be so fortunate in other parts of your life.
In addition, while waiting for one of these eventualities, you would undoubtedly grow more and more angry at your neighbour, making a friendly relationship between the two of you impossible. You would also lose a degree of selfrespect, since you would see yourself as the kind of person who can't cope with even a common everyday irritation. Clearly, non-ssertion is not a very satisfying course of action either in this case or in other instances.
