Question

1. use what you know about prefixes and roots to choose the meaning of omnidirectional.

a) a fear of directions
c) sending or receiving signals in all directions
b) the order of directions
d) a central location for receiving directions

Explanation:

The prefix "omni -" means "all". The root "direction" refers to a course or path. So "omnidirectional" means related to all directions. Option C which is about sending or receiving signals in all directions aligns with this meaning. Option A has "fear" which is not related to the prefix and root. Option B has "order" which is not indicated by the prefix. Option D has "central location" which is not in line with the meaning of the prefix and root.

Answer:

C. sending or receiving signals in all directions
