Since there is no question posted, I'll ask one. Name three types wood-cutting and list the pros and cons of each one.

Shelter-Wood-Cutting:  Pros: Sustainable, trees are left to grow back. Cons: Young trees can be damaged by wind.
Selective-Cutting: Pros: Most of the habitat is left. Cons: Process is invasive, expensive. Some trees do not repopulate well, such as pines and firs.
Clear-Cutting: Pros: Are there any? High profit. Cons: Causes environmental issues, e.g. habitat loss, soil runoff, deforestation, desertification.

Although that is correct, I was looking for a different answer.

Is it
The Great Green Wall? The initiative in Africa to combat desertification?

What two gases are responsible for acid rain? Include the reactions that produce their respective acids.

This is from a previous year and is not applicable this year.

Haha lol, test-writers in Green Gen don't always follow the rules so its good to know stuff from last year (I guess that's the advantage to having put up with Green Gen for an extra year :D ). But to answer your questions
The two compounds are SO2 and NOX. Depending on if its NO or NO2 different acids will form. But here they are

2SO2+O2-->2 SO3 
SO3 + H2O --> H2SO4

NO+H2O--> HNO2
NO2+H2O--> HNO3
