Long-term exposure to noises at high sound level may cause temporary or even permanent [A]. Noise level is measured in [B] and the symbol of the unit is [C].

Sound is a property measured in decibels. The louder a sound is, the higher the decibel level is and the more likely a sound is to damage an individual’s hearing. ------- from a physics standpoint, humans who have a high sensitivity to loud sounds should avoid environments that are characterized by high decibel measurements, including fireworks displays and loud concerts.Which choice completes the text with the most logical transition? Subsequently,eliminateBesides,eliminateNevertheless,eliminateThus,

1. Although pollution of land, sea and air has been well documented, the latest and the least recognisedversion is the swelling tide of noise which is engulfing urban as well as rural areas. This has long-termimplications on the ecology, health, and productivity of a fast developing country like India.2. Unlike other pollutants, noise lacks visibility, seldom registering on the consciousness, except asa trifling irritant to be dismissed at will, therefore, less likely to be perceived as a threat. Availabledata indicates that noise does pose a threat and is known to have caused a number of complications.Declining productivity among workers in certain industries has been directly correlated with noiselevels, particularly these under constant exposure to the menace.3. The first ever survey of the impact of noise on health, conducted by All India Institute of MedicalSciences, has established that noise not only impairs the physical and psychological functioning of thehuman organism, but also causes nausea, vomiting, pain, hypertension and a lot of other complications,including cardio-vascular complaints.4. A study by Post Graduate School of Basic Medical Sciences, in Chennai, confirms such conclusions. In50 per cent of industries, it was found that workmen exposed to higher intensities of noise in occupationalcapacities were often irritated, short-tempered, and impatients and more likely to resort to agitation anddisrupt production. This was true of units in heavy industrial pockets in and around the four metropolitancentres.5. Recreational noise, another ugly facet, is becoming more widespread in cities and towns. Loudspeakersare turned at full volume during marriages, festivals, jagrans, musical programmes, particularly atnight, without the least consideration for others. Even at 50 db sound can awaken a person from a deepslumber. As experiments have shown, loudspeakers with output from 60 to 80 db cause the pupils ofa slumbering person to dilate, with increasing intake of oxygen, resulting in palpitation. The effect ismore pronounced in narrow lanes. TV sets are played at full volume at prime time, invariably disturbingneighbours. Noise-making seems to have become the latest status symbol, be it an election campaign orslogan shouting or advertising ownership of a TV set.Page 2 NODIA Sample Paper 1 CBSE X EnglishClick the Following Button to See the Free MS/SolutionsAnswer the following questions, based on the passage above.i.
