<span>The correct answer is A. younger than. This is all just fancy ways of saying that if you cut open a mountain and look at the rocks, the ones on the top will be younger than the ones on the bottom. That is because of the ways that the rocks formed and the way things were deposited.</span>
Explanation:
All are benefits of virtualization.
A. Backup and recovery can be centralized at one location, even with world-wide subsidiaries. The management of backup and recovery is therefore centralized and streamlined over 24 hours.
B. Lower operating cost comes from centralized or clustered locations, and for less costs for maintaining and replacing physical machines.
C. Security is vital to a commercial business. Virtualization allows security to conform to uniform standards for all locations without scattered locations supervised / operated by local personnel with different security standards.
D. Streamlining and automated management tasks includes all of the above. There is no more need to schedule availability of particular types of machines at particular locations. All resources are available at any time (assuming proper design of resources). Tasks can therefore be automated with continuous production, hence productivity. This is the most important feature and advantage of virtualization.
E. Ability to run legacy programs is definitely an advantage, but in almost all case, this is an occasional requirement, so is lower in the importance of the advantages.
Answer:
Very little rainfall occurred, and then a long drought had started. For this reason, people of Chaco Canyon (Anasazi) left that place and never came back.
Explanation:
Scientists have found one possible cause by dendrochronology (the study of looking at tree rings) in the Chaco Canyon area. In the period between A.D. 1125 and 1180, very little rain fell in the Chaco Canyon. After 1180, rainfall briefly returned to normal. From 1270 to 1274, there was another long drought, followed by another period of average rainfall. In 1275, yet another drought began. This one lasted 14 years.
When the people of Chaco Canyon (Anasazi) started facing this little rainfall, they fall into water problems. Their problem started to solve when the rain became typical, but they again started facing the same problem when long draught had begun.
So, finally, they (Anasazi) decided to leave Chaco Canyon and never thought about the return back there.
