The Guam rail is a flightless bird found on the island of Guam. It builds a shallow nest on the ground and lays eggs throughout the year. There
are no native species of snakes on Guam, so the Guam rail had no
experience with snake predators until the brown tree snake was
accidentally introduced sometime between 1944 and 1952. These
snakes, which eat a wide variety of animal species, quickly established
a large population on Guam.
How was the Guam rail most likely affected by the introduction of the
brown tree snake?

The table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which city’s rocks are likeliest to experience frost wedging, and why? a) city a because the consistently subzero temperature would prevent water from melting b) city b because it is a wet region and the temperature fluctuates around the freezing point c) city c because it receives plenty of rain fall and the weather is moderately cool d) city d because the hot and dry weather would cause rocks to absorb water
