In one town, some people support a proposal to
build a shopping mall on a large, undeveloped
lot, because it would increase business and
create new jobs. as a trade-off, the shopping
mall would cause a decrease in the
(1) amount of air pollution
(2) volume of garbage and litter
(3) amount of wastewater entering the local
sewage system
(4) variety of wildlife populations in the area

If the people decided to build their shopping mall on the large, undeveloped lot which would build a lot of jobs and businesses this would probably also reduce the variety of the wildlife population in this area. (4). This is also the correct answer.

This would happen because building a huge project like this would affect the local wildlife population which would be forced to move to another location. 

B. The water in the glass entered the raisins.

Explanation:

The water moved into the raisins because of the unbalanced sugar/water content. There's a low concentration of water inside a raisin because it's dried, and most things move from high to low concentration, which is why the raisin absorbed the water. Another great example of this type of diffusion is spraying perfume in a room. At first, it's highly concentrated in one spot, but will move to other areas that have lower concentrations of it- filling the room. I hope this helped!
