Question 1

Statements: All maps are charts. Some charts are graphs. No graph is a diagram. Conclusions: I. Some maps are diagrams. II. Some charts are not diagrams. Which conclusion(s) follow?

Accepted Answer

Only II follows

Answer

Some charts are graphs and no graph is a diagram, so some charts are not diagrams (II follows); there is no direct path from maps to graphs/diagrams, so Conclusion I does not follow.
