Answer 1

Building a mass transit system is likely to have which of the following effects?
Okay... Lets walk through this..
This "mass transit system" the system could be magnetically driven which the question is not pertaining to what 'type' of transit system it is.
Traffic congestion would be much lower because so many people can use this system to get back and forth to destinations which will 'alleviate' the traffic congestion.
Increasing the temperature of the urban island, well this can be possible, yet the question is not directing you to what type of transit system this is. Also the question given has no link to an urban island unless within this test there is mention of an island...
AH' now since the answers given, have been broken down... Which answer do you choose. Good Luck
