In the question, a statement is given followed by two assumptions numbered I and
II. An assumption is something supposed or taken for granted. You have to consider the statement and the following assumptions and decide which of the assumptions are implicit in the statement. Statement: The Transport Authority has decided to install automated digital speed-display boards along major city avenues to curb over-speeding. Assumptions :
I. A section of drivers using the city avenues currently exceeds the prescribed speed limits.
II. Providing real-time visual feedback on current speed will deter motorists from over-speeding.

Assumption I is implicit: The decision to introduce a specific measures targeting over-speeding is only logical if the Transport Authority assumes that over-speeding is an active issue among motorists on those avenues. If all drivers strictly adhered to speed limits, the intervention would be redundant and unnecessary. Assumption II is implicit: The objective of installing these digital speed-display boards is to "curb" over-speeding. This takes for granted that the chosen mechanism (real-time visual speed feedback) will influence driver psychology and encourage them to slow down. Hence, both assumptions I and II are implicit in the given statement.
