First, the unit is words per minute, not the other way round because you're interested in how fast people can type, not how much time passes for every number of words they write or read (that would be minutes per word)
now, we know they do 4200 in 60 minutes. 
we need to divide 4200 by 60- first,

so the answer is, 70 words per minute
I think you made a typo in your answer and you meant 4600 instead of 4200 - then the answer is <span>C. 76 2/3 word/min</span>
 
        
        
        
C. A new source of freshwater
Explanation:
The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater. 
In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.
- A new source of freshwater provides new resources for the ecosystem. 
- In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress. 
- Water is essential for life.
- Fresh water sources are incentives for choosing to live in a place or not. 
- A fresh water source increases the carrying capacity for humans in a certain region.

<span>Characteristics that mentioned biomes have in common are:
- They are all forests, dominated by trees and other woody vegetation.
- They inhabit animal life with great microbial diversity.
- They all have big carbon sinks.
Still, trees different in a number of ways in these three biomes:
- </span><span>Tropical rainforest: Trees are evergreen and have large green leaves. Canopy is multilayered and dense, so there is a little light in the forests.
- </span><span>Temperate deciduous forest: Trees are deciduous, leaves are lost annually. Canopy is moderately dense, so there is more light than in tropical rainforests.
- </span><span>Boreal forest: Trees are evergreen conifers with needle-like leaves. Canopy is thick and permits low light penetration.</span>
