Subset: Paris

Superset: France

Being in Paris is sufficient to be in France, however being in France is not sufficient to be in Paris (could be in another city).

Being in France is necessary to be in Paris, however being in Paris is not necessary to be in France (could once again be in another city).

Another Ex:

A Honda is sufficient to be a car, however a car is not sufficient to be a Honda (other car brands exist).

A car is necessary to be a Honda, however a Honda is not necessary to be a car (other car brands exist).

Final Ex:

Lisa is at the grand crayon, therefore it is sufficient to conclude she is in USA. However, Lisa being in the USA would not be sufficient to conclude that she is at the grand canyon (could be elsewhere).

The USA is a necessary condition for Lisa to visit the Grand Canyon. However it is not necessary for Lisa to visit the Grand Canyon in order to be in the USA (could be elsewhere).

I'm struggling with the comparatives that require inferences so far. Everything else but #5 was simple to grasp, hope to get ahold of the inferences soon
