Which precedents did the u. s. constitution establish for other governments? select all that apply.
a) government power can be divided into two branches
b) citizens have basic rights that governments must safeguard
c) accused people are presumed guilty until proven innocent
d) people cannot be forced to testify against themselves

b and c is my guess but i'm kinda stuck.

I believe the answer is:B. citizens have basic rights that government must safeguard, people cannot be forced to testify against themselves

The basic rights that given by the constitution to its citizens prevent the Government from violating the things that should be had by humans in order to make our life valuable.
Example of basic rights: The right to live, the right to be free from torture and degradation, etc.

The answer is on suffrage experience.
