The high energy of X-rays allows them to pass through the human body.
The high energy of X-rays allows them to pass through the human body.
The high speed of X-rays allows them to be used safely on human patients.
The high speed of X-rays allows them to be used safely on human patients.
The rarity of X-rays in nature means they can be used in machines without other X-rays blurring images.

To determine why the student should propose the use of X-rays for producing an image of the interior of the human body, let's analyze the given options:
1. "The brightness of X-rays means they last a long time once they are produced by a machine." - This statement does not provide a valid reason for proposing the use of X-rays. The longevity of X-rays once they are produced is not relevant to the creation of an image of the interior of the human body.
2. "The high energy of X-rays allows them to pass through the human body." - This statement is accurate and provides a valid reason for proposing the use of X-rays. X-rays have higher energy compared to other types of electromagnetic radiation, which allows them to penetrate through soft tissues in the human body. This characteristic makes them useful in medical imaging to capture images of bones, organs, and other structures.
3. "The high speed of X-rays allows them to be used safely on human patients." - This statement is not relevant to the use of X-rays in medical imaging. The speed of X-rays does not play a role in their safety or effectiveness for imaging purposes.
4. "The rarity of X-rays in nature means they can be used in machines without other X-rays blurring images." - This statement is incorrect. X-rays are not rare in nature and are, in fact, produced by various sources such as X-ray generators. The rarity of X-rays is not a determining factor for proposing their use.
Based on the analysis, the statement that best explains why the student should propose the use of X-rays is:
- "The high energy of X-rays allows them to pass through the human body."
This characteristic of X-rays enables them to penetrate soft tissues and capture detailed images of the interior of the human body.
The correct response is:
The high energy of X-rays allows them to pass through the human body.
X-rays have high energy which allows them to pass through tissues and organs of the human body. This characteristic makes X-rays suitable for creating images of the interior of the human body as they can penetrate through the body and capture the structures, such as bones, that lie beneath the surface.
