Nares provide an opening for air to enter the nasal cavity.
Air enters the nasal cavity from the outside through two openings: the nostrils or external nares. The openings from the nasal cavity into the pharynx are the internal nares.
The nasal cavity and mouth join at the area in the back of the throat called the oropharynx . The pharynx is part of two body systems (the respiratory system and the digestive system) because it carries both air and food.
At the bottom the pharynx is divided in to two pipes- one for air and one for food. One pipe, the larynx, is for air only. It’s also called the voice box because it contains a pair of vocal cords that vibrate to make sounds when you talk.
A small flap of tissue called the epiglottis protects the larynx. When we swallow, the epiglottis covers the larynx to prevent food and liquid from going into the lungs.
The trachea (windpipe) is the part of the airway that continues below the larynx .
The carina is at the bottom of the trachea and is the point at which the trachea divides into the left and right main bronchus leading to the lungs.

Explanation:
They are surely better. I think that there is much less discrimination. Social media is full of opinions on this situation and everyone is thinking that all people should be equal. Nowadays, all races are having the same opportunity in life.
The best example for that is president Barack Obama who is the first Bi-racial presidential candidate and he was nominated by the other people which is showing how people are looking at that race relations situation and that it doesn't matter which race is someone.
I think that the situation is better because those people are standing for each other and doing their best. They were fighting for their rights trough many years and they deserved it.
Depending on how far the source where the signal is coming from is, radio waves travel at the speed of light. If the civilization lives in a star system that is 20 light years away from us, the signal would take 20 light years to reach us.
(1 light year = 1 normal year but traveling or moving at the speed of light).
