Well I'd say that your answer is informative because it said "explained our teacher". I hope this helps.

A “Thanking Oedipus for ridding them of the Sphinx, the Thebans made him king.”

D “O’Neal’s first basketball team in 1992 was the Orlando Magic in Florida.”

C. “Destruction of habitat is a known primary cause of extinction.”

A. cause/effect organization

Explanation:

The main purpose of the first passage is to explain the reasons why Oedipus ended up in the situation of having to marry Jocasta. The text explains that Oedipus was made king as a reward for ridding the Thebans of the Sphinx.

In this passage, the main idea that the reader should get is that which explains the beginning of O'Neal in basketball. Therefore, the statement that best explains this is that O'Neal's first team was the Orlando Magic in Florida.

The fact that destruction of habitat is a known primary cause of extinction is the main idea of this text. In this text, the author wants us to understand how it is that extinction occurs in animals with reduced habitats. He does this through the use of scientific explanations and hypothetical situations.

This is an example of a cause/effect organization, as the author presents both the origin of the conflict (the fact that Laius knew he would be killed by his own son) and the effect that this had on the story (the fact that Laius decided to leave his son to die).
