Question

The map shows the distribution of wild boars in the United States (shaded area).

A map of the United notes showing the distribution of wild boars in dark orange. Wild boars appear most often in Texas, California, and Florida, and along the southern notes.

Which of these facts about wild boars is best supported by the evidence provided?
Wild boars were brought to the United States by humans.
Wild boars have quickly spread through the United States.
Wild boars have established successfully mostly in areas with warm climates.

Answer 1

"Wild boars have established successfully mostly in areas with warm climates."

Reason: the shaded distribution is concentrated in southern states (Texas, Florida, California and along the southern U.S.), which are generally warmer. The map gives no information about how they arrived or how fast they spread, so the other statements are not supported.
