Design Process
why do engineers use graphics to record and communicate information?
All of the Above, Graphics help us understand how things work, graphics help us understand how things are related to each other, more information can be understood.
An engineers Notebook
All of the Above, also referred to as an Engineers Logbook, a Design Notebook, or designer's. A record of design ideas generated in the course of an engineer's employment that others may not claim as their own. An archival record of new ideas and engineering research achievements.
why did our ancestors create measurement standards?
All of the above,the need for standardization, to build things accurately, to be able to create drawings with directions.

What is the difference between sketching and technical drawing?
Sketching is free hand where as technical drawings are created using drafting tools, technical drawings are created to be used during the manufacturing or construction process. Both A and B
