<p>Test passes if the second and third lines below are identical, with two checkmarks (✓) followed by one cross (✗); and
also, if the first line is <em>either</em> identical to the other two, <em>or</em> has one checkmark followed by two <b>subscript</b> crosses.
If the first line has a checkmark followed by two normally sized crosses, the test fails. </p>
