jim crow laws.
the black codes.
racial integration.

Explanation:

For Question 39: During Reconstruction, the strong military presence in the South helped enforce the Civil - Rights Acts of 1870, 1871, and 1875. The black codes were restrictive laws against freedmen, Jim Crow laws came later and were for racial segregation, and Congressional approval was not the main enforcement mechanism.
For Question 40: The racial segregation of public facilities in the South was based on Jim Crow laws. Racial discrimination is a general concept, the black codes were different from Jim Crow laws and more immediate post - Civil War restrictions on freedmen, and racial integration is the opposite of segregation.

Answer:

Question 39: The strong military presence in the South during Reconstruction
Question 40: Jim Crow laws
