Official Solution:
There are two cities Armia and Banur, 50 miles away. A premium Bus service, Travel-One, has a non-stop bus service in the morning from Armia to Banur. Almost every day the bus remains filled to 90% of its capacity. The operator of Travel-One intends to fill up these 10% seats by making a halt enroute at Town Creepia.
Which of the following, if true, would strengthen the operator’s plan the most?
A. There are no additional expenditure incurred in terms of fuel and other resources due to the stoppage.
B. There are very limited bus services to other cities from Creepia.
C. The passengers using the bus service presently use it because of non-stop service.
D. The people of Creepia presently use private vehicles to travel to other cities due to limited means of public transport.
E. Travel-One generally operates its bus service keeping the revenue as a priority.
A. There are no additional expenditure incurred in terms of fuel and other resources due to the stoppage. Good for revenue and profit. But does not give any reason WHY the 10% seats should get filled up by making a halt at Creepia.
B. There are very limited bus services available at Creepia. A trap and very close to be the answer. Limited Bus service may mean there is no requirement of bus or there may be other transport available, which may be getting used and therefore, there is no demand for any other mode of transport.
C. The passengers using the bus service presently use it because of non-stop service. This actually may work as a weakener, as the people using it may stop using the bus service because of the halt.
D. The people of Creepia presently use private vehicles due to limited means of public transport. CORRECT. the catch and reason over B is "due to"... This means people are being forced to use their private vehicles due to lesser number of transport available. So surely there is a demand for public transport / buses. Perfectly fits in as a strengthener.
E. Travel-One generally operates its bus service keeping the revenue as a priority. Revenue may be a priority but how does it help in plan.. No it doesn't strengthen the plan.
