Answer:
The cave paintings may also be representations to leave a record of how these people live for future generations
Option (a) is true.
Step-by-step explanation:
The cave paintings serve as a record of how these people lived for future generations.
They provide us with insights into their culture, beliefs, and way of life.
The word "trace" is too vague to accurately describe the purpose of the cave paintings.
"Documentation" and "memoir" are both more formal terms that suggest a written record, which is not the case with cave paintings.
"Thrived" implies that the people who created the cave paintings were successful or prosperous, which may or may not be the case.
Therefore,
"record" is the best word to describe the purpose of the cave paintings, and "lived" is the most accurate verb to describe the way these people existed.
Option (a) is true.
