What does the law of individuality state about objects?

• All objects are identical.

• Objects are similar if made by the same machine.

• Objects lose individuality over time.

What is the significance of the law of individuality in CSI?

• It suggests all evidence is identical.

• It negates the need for evidence collection.

• It helps in identifying the uniqueness of evidence.

• It implies evidence is always contaminated.

Why is it crucial to secure a crime scene quickly according to the law of progressive change?

• To prevent media interference.

• It emphasizes the role of probability in identification.

• It allows for multiple interpretations of evidence.

What is the difference between inductive and deductive reasoning?

• Deductive reasoning is always uncertain.

• Deductive reasoning is based on observations.

• Inductive reasoning is based on established facts.

• Inductive reasoning generates knowledge from observations.

What does the principle of comparison emphasize?

• Comparing unrelated samples is effective.

• Comparison is unnecessary in forensic science.

• Only similar items can be compared.
