The answer would be A. Have the Defendant pay a higher bail amount... Judges I don't believe can take away a person right of bail because of the "innocent until proven Guilty". They won't have the defendant followed by the police 24/7 but they may have them monitored. And judges CANNOT take away a person right to a trial.
Many primary civilizations started in river valleys because for the cities in each civilization an important portion of the population existed in cities. Large-scale farming was a requirement to feed the large populations. Fertile due to flooding the land by rivers was home to lush plant life and an outstanding place to plant and grow crops. The close source of water permitted for irrigation for the large-scale farming as well as drinking and bathing. Water also intended animals and animals meant food so this was another advantage to settling in river valleys. Settling and living in river valleys later main to further development of civilizations and new patterns of living such as trade and communication by means of the river for transportation.
