Yes I suppose they could pass such a law as long as all the branches agree and emergencies are exempt.
Two things that the Radical Republicans insisted be part of their Reconstruction plan was that the military would stay in the South to supervise the transition, and that the newly freed slaves would be offered all the freedoms of whites in the South.
I would go with issues that contributed to the civil war.
Racism and Women's rights were a huge controversy during the civil war and the 15th amendment gives every one the right to vote, no matter what race, gender, or past slavery.
Sorry about the late answer!
Despite not providing the picture, there is enough information in the question to understand that the correct answer is alternative A) "At least 500 Million Years"
If the fossilized being lived around 500 million years ago, it means that the rock must be at least about that age.
Alternatives B and C are inconclusive, since the rock might have formed before, and with the information presented it's impossible to tell it's exact age. We can only tell that it's at least 500 million years old because of the fossil of a specimen that lived about 500 million years ago.
