Question rk4: Name of document you are referring to with url if on-line.
              Or paste in the text.

Question rk5: Supporting telemetry? E.g., show locations of temperature
              sensors, how often sampled, and values from telemetry.

Question rk6: Show mechanism how a short to ground in the Command Module
              causes a fire in the Service Module.

Question rk7: Name the systems downstreams of the short, the problems
              encountered, and the explain the mechanisms for how the
              short caused the problems.

It is your choice whether or not to answer questions or to spend your time on
other things. See Derek's comments.
