Answer:
C. have done
Explanation:
A, B, D use the present continuous (progressive) tense, while C. uses the present perfect tense.
Those with disabilities whether physical (like missing a limb, or being blind) or intellectual (like Down syndrome and autism) face challenges that those without the disability do not. Finding a job they can actually do may be an issue, or finding a well paying job may be difficult. Those who have gone to jail/prison may face issues being hired because of their past. Employers may be hesitant to hire someone who has been convicted of breaking the law, and may find it hard to trust them if hired, leading to possible difficulty being promoted into higher positions. Illegal immigrants may have challenges when it comes to paperwork with jobs, as many jobs request to see your SS card and record this information. Immigrants may also be discriminated against. If doing under the table work, they may be exploited and paid far less because their employer knows of their situation. To overcome these barriers, employers must be more open to non conventional workers and insure all employees are being treated equally, which is granted with the Equal Protection Clause of the 14th Amendment. Some employers have taken steps such as working with the govt. to hire those with intellectual disabilities. The same also goes for those divorced of crimes that are deemed to have been rehabilitated and are making their way back into society.
