B is the answer and I hopes this helps
Answer:
The correct answer is A)
To limit the potential flooding damage that could result if an earthquake happens and the dam spills over
Explanation:
According to the text, seismic risks are very high for dams in that region. One of the reasons is that some of the dams were built many years ago when civil engineers didn't have information about what an earthquake could do to dams.
Citing an occurrence that happened in 1899 as an example where thousands of people were killed as a result of a failed dam, it is feared that should same reoccur, the loss may be more because about 300,000 people occupy the flood zone along the Alameda Creek below the dam.

Answer:
For many centuries, smallpox devastated mankind. In modern times we do not have to worry about it thanks to the remarkable work of Edward Jenner and later developments from his endeavors. With the rapid pace of vaccine development in recent decades, the historic origins of immunization are often forgotten. Unfortunately, since the attack on the World Trade Center on September 11, 2001, the threat of biological warfare and bioterrorism has reemerged. Smallpox has been identified as a possible agent of bioterrorism (1). It seems prudent to review the history of a disease known to few people in the 21st century.
Edward Jenner is well known around the world for his innovative contribution to immunization and the ultimate eradication of smallpox (2). Jenner's work is widely regarded as the foundation of immunology—despite the fact that he was neither the first to suggest that infection with cowpox conferred specific immunity to smallpox nor the first to attempt cowpox inoculation for this purpose.
