Direction: Read the following passage carefully and answer the questions given below.

I felt the wall of the tunnel shiver. The master alarm squealed through my earphones. Almost
simultaneously, Jack yelled down to me that there was a warning light on. Fleeting but
spectacular sights snapped into ans out of view, the snow, the shower of debris, the moon,
looming close and big, the dazzling sunshine for once unfiltered by layers of air. The last

incorrectly stated.

Direction: Read the following passage carefully and answer the questions given below.

The Indian middle class consist of so many strata that it defies categorisation under a single
term class, which would imply a considerable degree of homogeneity. Yet two paradoxical
features characterise its conduct fairly uniformly; extensive practice and intensive abhorrence
of corruption.

In the several recent surveys of popular perceptions of corruptions, politicians of course
invariably and understandably top the list, closely followed by bureaucrats, policemen,
lawyers, businessmen and others. The quintessential middle class. If teachers do not figure
high on this priority list, it is not for lack of trying, but for lack of oppurtunities. Over the
years, the sense of shock over acts of corruption in the middle class has witnessed a steady
decline, as its ambitions for a better material life have soared but the resources for meeting
such ambitions have not kept pace.

What is fascinating, however, is the intense yearning of this class for a clean corruptionless
politics and society, a yearning that has again and again surfaced with any figure public or
obscure, focus on his mission of eradicating corruption. Even the repeated failure of this
promise on virtually every man's part has not subjected it to the law of diminishing returns.
