Hello, I need help with part B$.$

There is evidence that, other things equal, a $10$ percent increase in the number of workers with a particular skill level leads to about a $4$ percent decline in wages for workers with that skill level. In addition, this $10-$to$-4$ ratio appears to hold true whether the increase in labor supply is caused by domestic changes in labor supply or by an influx of immigrant workers.
