The chorus appears five times in Oedipus Rex, and each ode they sing makes a reflection upon each climatic situation. The first song of chorus sound immediately after Oedipus has declared his resolution to trace the murderer of Laios. The chorus has already learnt the message from Delphi and consequently expressed uncertainly about who the murderer might be. The choric song also intensifies the sorrowful condition prevailing in the city. Sickness has our powered the city like an epidemic and no remedy is available. The second song is introduced just after Oedipus is accused of being a murderer himself. The chorus is not prepared to believe the allegation against Oedipus and instead urges the horrible murdered to free from the city immediately. The third song is a meditation upon a serious defect of Oedipus's nature. In his dealing with Creon, Oedipus has exhibited extreme pride, arrogance and ill-temper. The chorus indirectly speaks of the possible fall of tyrants through pride. The fourth ode comes up while Oedipus is occupied by the crisis of his identity. The chorus speculators on some romantic affair between gods and nymphs on the mountain side and assume that Oedipus must be such semi-divine product. The final choric song is an interpretation of Oedipus's fall and reflection upon short-lived happiness of human beings. The choric songs thus intensify and analyze the developing dramatic situation helping the audience to understand the drama more fully.
When animals are taken from their natural habitat, they are placed in secluded cages where their natural habitat is recreated, to the best of the zoo’s abilities. However, certain aspects such as ambient temperature in an animal’s natural habitat cannot be recreated perfectly. Animals live around the world for a reason. The main reason is that their natural habitat is associated with a particular climate and eco system, one which is reliant upon all of the natural plants and animals who also share that habitat. Nocturnal animals are those who sleep during the day and forage during the night. When nocturnal animals are taken from their natural habitat and placed inside of a zoo, with standard day time operating hours, it can be incredibly difficult for the animals to maintain their normal sleeping and activity plans due to a high rate of traffic often banging on their cage or calling to them during the day.
The science revolution attributed to Thales began gaining political force, and this play offered a warning to the new thinkers. Kitto interprets the play as Sophocles' retort to the sophists , by dramatizing a situation in which humans face undeserved suffering through no fault of their own, but despite the apparent randomness of the events, the fact that they have been prophesied by the gods implies that the events are not random, despite the reasons being beyond human comprehension.  Through the play, according to Kitto, Sophocles declares "that it is wrong, in the face of the incomprehensible and unmoral, to deny the moral laws and accept chaos. What is right is to recognize facts and not delude ourselves. The universe is a unity; if, sometimes, we can see neither rhyme nor reason in it we should not suppose it is random. There is so much that we cannot know and cannot control that we should not think and behave as if we do know and can control.
