Answer 1

I think the correct answer from the choices listed above is the first option. Astrology is not considered science because it does not make testable predictions. Astrology consists of a number of belief systems that hold that there is a relationship between astronomical phenomena and events or descriptions of personality in the human world. 

Answer 2

1) Astrology does not make testable predictions.

One of the reasons why astrology isn't a science is because their horoscopes' predictions aren't testable, their quality and genuineness isn't determined as they are too general, not specific at all, and any stated outcome could apply to anyone, or not apply at all. Nowadays, it is very common that astrologist suggests "today's prediction" of Virgo people, and that thousands of Virgo people claim that the prediction didn't become a reality, but perhaps such prediction was a reality for a scorpion person, for example.
