the arrival of another herbivorous mammal

the presence of a greater number of predator snakes

Answer 1

The condition most likely to lead to an increase in a field mouse population is the disappearance of a bird species that preys on the mouse.

With the predatory bird gone, there would be fewer predators to control the mouse population, allowing it to increase. In contrast, the other options would either introduce competition for resources (herbivorous mammals) or increase predation pressure (predator snakes), both of which could lead to a decrease in mouse population.
