Which hypothesis will most likely lead to further investigation and, potentially, a theory?
Answer
A
If all humans take swimming classes, then every human will become a better swimmer because humans will spend most of their time in water.
B
If worms can survive living near underwater volcano vents, then life may evolve adaptations that allow survival in extreme environments.
C
If dreams are based on life, then nightmares are based on fantasy because nightmares are too scary to be real.
D
If senior citizens believe in the act of hypnosis, then hypnosis can cure them of getting older because believing works wonders.
Explanation
