Robins migrate south during the winter months to avoid harsh conditions and then return north during the summer. What environmental condition are the robins most likely responding to in order to determine when the seasons are changing?

A.)The tilt of Earth on its axis.
B.)Fluctuations in predator populations.
C.)Changing length of daylight hours.
D.)Increasing availability of water.

The answer is A or C because they wouldn’t just fly north because of predators and water availability so the Robins can either sense the tilt or can tell by the day hours.

Hamlet's fourth soliloquy is probably his most famous one - "to be or not to be."it is rather different from his previous soliloquies because now he is contemplating something that didn't come up before - suicide. he is thinking whether it is worth it to fight to find his father's murderer when in the end all of them are going to die, so why not die sooner than later. he is contemplating if he should go on fighting or just kill himself and end it all, which is why this soliloquy in particular is rather depressing, hesitant, and gives a deeper insight into hamlet's madness.
