D. The railway did not increase the frequency in proportion to the increase in the number of commuters in the past one year
Feedback For 1: Here the commuters called on the strike in a response to the accidents which take place due to overcrowding and are demanding increase in the frequency of trains, assuming that if the frequency increases, then lesser number of such accident would take place. Hence, 1 is an assumption.
For 2: From the statement “increase in the number of overcrowding “it can be concluded that, the trains in the Mumbai suburban run overcrowded. Hence, 2 is a conclusion.
For 3: In the statement, there is no reference to intension of the railway authority. Hence, 3 is out of context.
For 4: As the number of accidents is increasing in the past one year, it can be inferred that, the frequency of trains did not increase in accordance to the increase in the number of commuters. Hence, 4 is an inference.
