Which of the following is true about abstract and nonabstract existence? (select the best answer)
Nonabstract entities are also called physical entities, are acted upon by gravity, and interact with other nonabstract entities.

All entities that exist, whether abstract or nonabstract, are perceived as existing.
All of the above are correct.

My friend has this whimsical "theory of everything" called the little green men theory. According to this theory, all physical interactions are caused by invisible little green men who push things around. For example, things fall because invisible little green men push them towards the ground. Also opposite charges attract because the invisible little green men push them towards each other. What is wrong with my friend's theory? (select more than one)
It's too generic and doesn't give quantitative predictions.
If the men are invisible, they can't be green since green is a visible color.
My friend drinks too much coffee and stays up too late at night thinking about how to develop a theory of everything.
