Explanation:

One similarity between the laws being challenged in the United States Supreme Court cases of Plessy v. Ferguson (1896) and Korematsu v. the United States (1944) is that "specific groups of people were being targeted based on race or ethnicity."

The above statement is true because Plessy v. Ferguson (1896) is where the Supreme Court ruled that it is constitutionally right to have racial segregation in as much the segregated facilities were equal in quality.

Similarly, the Korematsu v. the United States (1944) is where the Supreme court ruled that it is constitutionally right to remove the Japanese Americans from the West Coast Military Area during World War II.
