Question

read paragraph 1.
do you worry about the number 13 or breaking a mirror? do you try to avoid black cats or walking under a ladder? if so, youre probably superstitious.
how does the structure of paragraph 1 contribute to the passage as a whole?
the questions and answer show how much and greatly peoples habits can vary.
the questions and answer determine where some of the earliest myths began.
the questions and answer detail the rituals practiced by different communities.
the questions and answer explain a term that is key to understanding the text.

Explanation:

The paragraph uses two questions about common superstitious behaviors and then answers by defining "superstitious". This structure explains the key term "superstitious" which is essential for understanding the text. The first option is incorrect as it's about habits varying, not habits. The second is wrong as it doesn't discuss myth origins. The third is incorrect as it's not about community rituals. Only the fourth option matches the purpose of explaining a key term.

Answer:

The questions and answer explain a term that is key to understanding the text.
