According to the modern view of existential import, which of the following propositions has existential import?

A) All dogs are animals.
B) Some unicorns have horns.
C) All students who miss three or more classes will fail the course.
D) No news is good news.
E) No S is P.

In the modern view of existential import, any proposition that states the existence of at least one thing within its subject class has existential import. In proposition B, "some unicorns have horns," it is implied that there exists at least one unicorn in the subject class, therefore it has existential import. The other options do not make any claims about the existence or non-existence of entities within their subject classes.
