The answer to this would be gunpowder
The correct answer is answer C ("The article will be biased because the historian is using only one source about the ruler").
If a historian only took this one scroll to write a biography on its subject (the ruler), it would most likely be extremely misleading and inaccurate. There's no way of getting closer to the truth of any subject without contrasting a variety of opinions from different sources. What if people working for this ruler wrote it in a way that made him look good? What if it was written under pressure? What if it was a complete lie? These and many other questions should come to mind as possible ways in which relying on one source might compromise historical facts.

The answer is Supervisor
When searching captured and detained personnel, the Supervisor will be responsible for identifying and positioning all the members.
This is important, since each and every team member has been allocated tasks, job description and responsibilities. Only when every one will follow these, would overall discipline and cohesion of the team work.
In such circumstances, it is important that only the Supervisor carries out these tasks and no one else.
Interchangeable parts are parts (components) that are, for practical purposes, identical. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting (such as filing). This interchangeability allows easy assembly of new devices, and easier repair of existing devices, while minimizing both the time and skill required of the person doing the assembly or repair.
The concept of interchangeability was crucial to the introduction of the assembly line at the beginning of the 20th century, and has become an important element of some modern manufacturing but is missing from other important industries.
