Answer: that keeping out foreign imports allows the goods and services to be produced by domestic workers.
Step-by-step explanation:
If goods and services that are usually imported are kept out of the country through import controls, the local producers would have to step in to meet the demand for those goods and services.
In doing so they will have to hire domestic workers for the production of those goods and services which therefore imply that limiting the imports of those goods and services created jobs for the local workforce.
