What age groups perceive illness as a punishment?

Answers

Answer:

Pre-schoolers may perceive illness and death as a punishment.

Explanation:

Researchers such as Roger Bibace and Mary E. Walsh studied the concept of illness and death among the children. So they studied this concept in children from age group of 4-12 years old.

While asking the questions about the illness and death to 4-7 (Pre-schoolers) years children, they found out that children of this age perceive that the illness they suffer is a result of  their mischievous behavior and has come upon them as a punishment.

This concept of illness as a punishment in children of this age comes from the idea when their parents warn them not to behave badly or something wrong might happen to them.

So, the correct answer is that children's group of pre-schoolers (somewhat aged between 4-7 years old) perceive that illness is a punishment.

Answers

Answer:

So she gave her legal right to drink alcohol and was being ethical.

Answers

The correct answer is B. Cuneiform

Explanation:

The image presents an ancient form of writing based on symbols rather than on individual letters; this form of writing was known as the cuneiform writing system and developed in the Sumerian civilization (Mesopotamia).

Besides this, cuneiform is considered as a major contribution of this Ancient civilization because it registered important information about Sumer civilization and was one of the first writing systems.
