X', a fisher woman alighted from a tramcar. While the conductor was helping her to put the fish basket on her head, a motor cyclist 'Y' passed the tram and immediately afterwards negligently collided with Z's motor car. 'Y' was killed.

The question given below consists of a statement, followed by three arguments numbered I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments and which is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: A moment of silence, please, for the world’s cheapest car, which had all but has died in India. It was almost 10 years old. The Nano’s death was confirmed by production numbers: Tata Motors Ltd. produced 1 unit in June, down from 275 in the same month last year. Exports were zero, versus 25 in June 2017. The company acknowledged that the car in its ‘present form cannot continue beyond 2019’. Why? Arguments: I. The expiry of the ‘people’s car’, as Tata Motors branded it in 2008, holds lessons for automakers hoping to make it in India: While consumers may be value-conscious, cutting costs to the bone in pursuit of a gimmicky claim to fame is of no use if the end result is a second-rate vehicle with a tendency to catch fire.  II. The Nano’s failure to sell stands is in stark contrast to the rest of the Indian car market. From motorbikes to cars and trucks, growth in every segment is picking up.  III. This is a market where electric vehicles are non-existent and the chatter over fancy ideas such as future mobility and autonomous vehicles, which pervades the rest of the auto world, is muted.
