Question

as human travel increases, the number of introduced species likely
decreases.
increases.
stays the same.
is eliminated.

Explanation:

When human travel increases, people move more between different regions. This movement often leads to the unintentional or intentional transport of species (e.g., plants, animals, microorganisms) from their native habitats to new areas. So, the number of introduced species (species moved to non - native areas) is likely to increase. The other options don't make sense: a decrease would be opposite to what happens with more travel, staying the same ignores the impact of increased human movement, and being eliminated is not related to the introduction of species due to travel.

Answer:

B. increases
