HIV or other sexually transmitted diseases.
Answer:
Is selective.
Explanation:
The fact that attention is selective means that we can focus on something in particular and turn off all the other things that we perceive in an environment. This is helpful when we want to focus on one thing, like listen to our professor, so we do not pay attention to what is going on in the room like mates talking, someone chewing, the noise outside, etc.
Because when people are educated, they are aware of the social values and the events happening around.
