Mother to Son figurative language What other figurative language is in this poem besides metaphor?

Well, son, I'll tell you;
Life for me ain't been no crystal stair,
It's had tacks on it.
And splinters,
And boards tor 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'
- comers.
And sometimes goin*
in the dark
Where there ain't been no light.
So, boy, don't you tum 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

its hard for me to see which word is supposed to be in bold. if i knew then i would be able to better.

michael’s company should invest in the updating of every section as well as data and processes technology and software. through the analysis of the manufacturing process, the company can take a clear approach towards the best way to improve not only the process but also de final result. some of the main problems that manufacturing companies face are the waste of material due to disorganized processes and the lack of real-time process checkings. this can be solved with specific software and machines that can turn paperwork into the digital era and that will reduce the time employees take on that, being this time better apply to control the production process and communication among different sectors of the company, the product will be made in shorter time with better quality and more profit

i believe that's the correct answer
