Read the following passage and answer the question by choosing the most appropriate option from the ones given below.

(1) The recent apparently successful, prediction by mathematical models of an appearance of El Nino-the warm Ocean current that periodically develops along the Pacific coast of South American-has excited researchers. Jacob Bjerknes pointed out over 20 years ago how winds might create either abnormally warm or abnormally cold water in the equatorial Pacific Nonethless, untill the development of the models no one could explain why conditions should regularly shift from on to the other, as happens in the periodic oscillations between appearances of the warm El Nino and the cold so-called anti- El Nino. The answer, at least if the current model that links the behavior of the ocean to that of the atmosphere is correct, is to be found in the ocean.

(2) It has long been known that during an Ek Nino, two conditions exist: (1) Unusually warm water extends along the eastern Pacific principally along the coast of Ecuador and Pent, and (2) winds blow from the west into the warm air rising over the warm water in the east. These winds tend to create a feedback mechanism by driving the warm surface water into a "pile" that blocks the normal upweling of deeper, cold water in the east and further warms the ester water, thus strengthening the wind still more. The contribution of the model is to show that the winds of an El Nino, which raise sea level in the east, simultaneously send a signal to the west lowering sea level, According to the model, that signal is generated as a negative Rossby wave, a wave of depressed, or negative, sea level, that moves westward parallel to the equator at 25 to 85 kilometers per day. Taking months to travers the Pacific, Rossby waves marth to the western boudary of the Pacific basin, which is modelled as a smooth wall but in reality consists of quite irregular island chains, such as the Phillippines and Indonesia.

(3) When the waves meet the western boundary, they are reflected, and the model predicts that Rossy waves will be broken into numerous coatal Kelvin waves carrying the same negative sea-level signal. These eventually shoot toward the equator, and then head eastward along the equator propelled by the rotation of the Earth at a speed of about 250 kilometers per day. When enough Kelvin waves of sufficient amplitude arrive 250 kilometers per day. When enough Kelvin waves of sufficient amplitude arrive from the western Pacific, their negative sea-level signal overcomes the feedback mechanism tending to raise the sea level, and they begin to drive the system into the opposite cold mode.

Question-125 : Read the following statements carefully:

(A) Negaive Rossy waves would cease to be generated in the eastern pacific

(B) The sea level in the eastern Pacific would increase
