Question

is observation?
As hominids evolved, their eyes increased in size and became more forward facing. Which of the following can be inferred from this observation? Hominids became more dependent on vision over time and less so on their other senses. 

Hominid depth perception decreased, and eye size increased to compensate. 

Hominid brains increased in size, which required their sensory organs to increase in size as well. 

Hominids were less likely to sustain injuries when their eyes faced the direction of their motion.

Answer 1

 The answer is Hominids became more dependent on vision over time and less so on their other senses.  This statement is related to the general decrease in the importance of smell and the increasingly significant use of vision. The stereoscopic (three-dimensional) vision and the appropriate perception of the resulting depth enabled the development of visual acuity over time.
