If a new housing development goes up, the original ecosystem can repair itself.
a. true
b. false

False. When a new housing development goes up, the original ecosystem will take years to repair itself. This is why modernization is such a huge threat to the overall environment. A lot of ecosystems are destroyed to build these homes and as a result, many organisms within the thriving environment are displaced and destroyed. This is the reason why a lot housing development programs are now gearing towards a more sustainable form of construction. 

Very hard to understand

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
