As part of continuing efforts to control illegal immigration, the US government should institute a system of internal passports similar to those in European nations. Drivers’ licenses currently serve a kind of internal-passport function, but this system is severely limited because not all states require the same documentation before issuing photo ID. Illegal workers can get a driver’s license in one state with lax regulations and use it as identification in another state with stricter regulations but better-paying jobs. Internal passports will keep illegal workers from slipping through the cracks by standardizing forms of photo ID. Which of the following is most similar to the passage above in logical structure?A. National standardized college entrance exams replace exams written independently by test administration services affiliated with groups of universities. B. A national association of doctors approves standards for diagnosis and treatment of childhood development disorders, and these standards are used in private clinics across the country. C. Resale values of used cars are discussed, standardized, and published in an industry manual also available to independent buyers and sellers. D. The distance between rails of train tracks is standardized across the country, allowing trains built by any manufacturer to travel along any rail line. E. Employment applications and hiring processes for a national restaurant chain are standardized in order to ensure uniform quality among employees.
