Stereochemistry Terminology

When describing the relationship of isomeric compounds the verbs must and might carry very different meaning. The first is a constraining necessity and the second a possibility. This distinction is an important feature of this question, in that one word or the other is used in each statement.

Which of the following statements are true for two pure isomeric compounds, both of which are chiral?
First select problem 1. or 2., and then check the boxes beneath all the statements you believe to be true.
(note, not all the statements are the same)

1. must statements.
they must be meso isomers
 they must be tautomers
 they must be enantiomers
 they must be diastereomers
they must both be optically active
 they must be constitutional isomers
 they must have different nmr spectra
 none of these statements are true
2. might statements.
they might be meso isomers
 they might be tautomers
 they might be enantiomers
 they might be diastereomers
they might be stereoisomers
 they might be constitutional isomers
 they might have different nmr spectra
 none of these statements are true
