Answer:
Regarding wild boar, the fact that is best supported by the evidence provided is wild boars have established successfully mostly in areas with warm climates.
Step-by-step explanation:
The wild boar (Sus scrofa) is a mammal from Africa, whose capacity to adapt to the environment is high. However, it is usually found in warm climates where it has a good supply of water and food.
According to the description of its distribution on the map, the states where it is found —predominantly Texas, California and Florida— verify the fact that they can be found mostly in warm climates, where they have found an ideal environment for their development..
About the other options:
- Wild boars were brought to the United States by humans. This is true, but it is not a fact that can be deduced from the information on the map.
- Wild boars have quickly spread through the United States. The map does not show this information.
- Wild boars have a high reproductive rate and no natural predators. The map does not show this information.
