Assumptions:
Comparative prices of all the articles in June and December 2005 were available.
Prices of personal computers were higher in the first six months than the last six months of 2005.
Since prices of personal computers show the highest decline among all the articles, it implies that the comparative prices of all the articles was known. So, I is implicit. Also, it being given that prices of computers showed decline during the last six months, it means that they were higher in the first six months. So, II is implicit.

8. Statement: Due to substantial reduction in fares by different airline services, large number of passengers so far travelling by upper classes in trains have switched over to airline services.
Courses of Action:
The railways should immediately reduce the fare structure of the upper classes substantially to retain its passengers.
The railways should reduce the capacity of upper classes in all the trains to avoid loss.
Airlines, being convenient and faster means of transport, people would surely prefer it to the railways if there is a marginal difference between the fares. Hence, a considerable gap between the two fares is a must for the railways. So, course I follows. Following course II would reduce the volume of passengers. Hence, II does not follow.
