Instruction: Identify the assumptions that must hold for the statement to be valid, then choose the correct option.
Statement: To reduce traffic congestion in urban areas, cities should invest in public transportation infrastructure, even though it requires significant initial investments.
Assumptions:
I. Public transportation can effectively reduce traffic congestion.
II. The initial cost of building transportation infrastructure is high.
III. People are willing to shift from private vehicles to public transportation.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Only I and II are implicit.
Assumptions:
I. Implicit (Public transport is suggested as a solution, so it must be assumed that it can reduce traffic congestion.)
II. Implicit (The statement clearly mentions that it requires significant initial investments.)
III. Not implicit (The statement does not necessarily assume people are willing to shift; it only suggests investment in infrastructure.)
