Assertion: a wireframe model can report the volume of the object it represents. Reason: it stores the complete geometry of every edge.

  • A.the assertion is false although the reason offered is a true statement in itself
  • B.both the assertion and the reason are true and the reason explains the assertion
  • C.both the assertion and the reason are true but the reason does not explain the assertion
  • D.the assertion is true but the reason given for it is false

Answer: A

Correct answer: the assertion is false although the reason offered is a true statement in itself

It is true that a wireframe stores every edge exactly, but edges do not enclose anything: the model has no surfaces and therefore no inside, so no volume can be computed. It is also why a wireframe can be genuinely ambiguous about which face is nearer. Volume requires a surface or a solid model.
