pretend you have a section of obliterated text that was overwritten with a marker. it cant be seen using any light - based techniques at the moment. you could use which of the following to help you visualize the original ink?
options:

• bleach
• a mirror
• ethyl alcohol

Explanation:

To visualize original ink overwritten by a marker (not visible via light - based methods), a warm flame can be used. Some inks are heat - sensitive, and applying a warm flame can cause the original ink to become visible as the heat affects the ink or paper in a way that reveals the underlying text. Bleach would damage the paper/ink, a mirror is for reflection (not helpful here), and ethyl alcohol is not typically used for this purpose.

Answer:

A warm flame
