Answer 1

Answer they are all true.

Step-by-step explanation:

The Unabomber had no identity until he finally confessed in 1998. Therefore, the answer is true, (its almost like a trick question.)

The Polygraph machine does measure physical changes in the body, so the answer is true.

False positives are when the examinee tells a truth but it is recorded as a lie.
