DIAGRAMMING DILEMMA - LEVEL 2
Venn diagrams are often used to organize information that compares and
contrasts two or more different objects. In our diagram, circle B
represents black holes while circle N represents neutron stars.
Carefully read over the list of descriptive phrases found below. The
number of a phrase that describes both a neutron star and a black hole
should be written in the overlapping section of the two circles. The
number of a phrase that describes only a black hole should be written in
the non-overlapping section of circle B. The number of a phrase that
describes only a neutron star should be written in the non-overlapping
section of circle N.
