[Anyof rule example]

Please label hydrogen atoms connected with left carbon atom.

[Complex grading example]

Describe carbon molecule in LCAO-MO.

[Another complex grading example]

Describe oxygen molecule in LCAO-MO

[Individual targets with outlines, One draggable per target]

Drag -Ant- to first position and -Star- to third position

[SMALL IMAGE, Individual targets WITHOUT outlines, One draggable per target]

Move -Star- to the volcano opening, and -Label3- on to the right ear of the cow.

[Many draggables per target]

Move -Star- and -Ant- to most left target and -Label3- and -Label2- to most right target.

[Draggables can be placed anywhere on base image]

Place -Grass- in the middle of the image and -Ant- in the right upper corner.

[Another anyof example]

Please identify the Carbon and Oxygen atoms in the molecule.

[Again another anyof example]

If the element appears in this molecule, drag the label onto it
