1. $\mathrm{E}_{\mathrm{b}}>\mathrm{E}_{\mathrm{d}}>\mathrm{E}_{\mathrm{c}}>\mathrm{E}_{\mathrm{a}}$

2. $\mathrm{E}_{\mathrm{a}}>\mathrm{E}_{\mathrm{c}}>\mathrm{E}_{\mathrm{d}}>\mathrm{E}_{\mathrm{b}}$

3. $\mathrm{E}_{\mathrm{c}}>\mathrm{E}_{\mathrm{a}}>\mathrm{E}_{\mathrm{d}}>\mathrm{E}_{\mathrm{b}}$

4. $\mathrm{E}_{\mathrm{b}}>\mathrm{E}_{\mathrm{a}}>\mathrm{E}_{\mathrm{d}}>\mathrm{E}_{\mathrm{c}}$
