Well, son, I'll tell you: Life for me ain't been no crystal stair.

It's had tacks in it,

And splinters,

And boards torn up,

And places with no carpet on the floor - Bare.

But all the time I'se been a-climbin' on,

And reachin' landin's,

And turnin' corners,

And sometimes goin' in the dark

Where there ain't been no light.

So boy, don't you turn back.

Don't you set down on the steps

'Cause you finds it's kinder hard.

Don't you fall now -

For I'se still goin', honey,

I'se still climbin',

And life for me ain't been no crystal stair.

—“Mother to Son,”
Langston Hughes

What is the central idea of the poem?

Life is not easy, but there are places along the way for children and parents to rest.
Life is not an easy journey, but children should keep climbing, just like their parents.
Life is not easy, but if it were too easy, children would not listen to their parents.

On a map showing the employment density of an urban area that follows the urban realms model, which of following statements best describes what the distribution of jobs might look like? (3 points) jobs closely follow major transit routes. jobs appear to be shifting from the inner to outer core. most jobs are concentrated around the central business district. jobs are distributed roughly in circles. several edge cities contain high numbers of jobs. which of these is not a criticism of the concentric zone model? (3 points) it does not accurately describe cities after the rise of suburban development. it only applies to cities that grew after the development of the automobile. it fails to address the development of cities outside of the united states. it assumes that inner-city areas will always be repurposed instead of abandoned. it places too much importance on the traditional central business district.
