Answer:
The relationship an infant has with his or her primary caregiver is most important.
Explanation:
During the early stages of development, in the infancy, the child has his/her parents and who is closer to him/her as a primary reference. It's at this moment that child will begin to understand the world and the rules that must be followed. The parents or caregivers are responsible for this learning process.
During World War I, 116,516 US soldiers were killed and 204,002 were wounded. If you add those two numbers together, the total number of US soldiers killed or wounded was 320,518.
You can represent that as a fraction of the current population of Chicago like this:

For simplicity's sake (since I assume the Chicago population number is an estimate), let's round the number of soldiers killed or wounded down to 300,000. That would look like this:

We can simplify that down a lot by dividing the number of soldiers and the number of Chicagoans by the least common denominator of 300,000. That would give us this fraction:

So for every 1 US soldier killed or wounded in World War I, there are 10 Chicagoans living in the city today.
Answer:
The media affects which issues are important by what they broadcast/inform viewers about. Often the public watch or read the news to get the main events about what is happening around the world. It depends on what the media shows on what the people think is important.
