    Hahahahahaha, Dr Russ. That's so funny.
    But it's true. :D

    Let's spare Matt some embarrassment. Here are the answer options:

    A. The compound of potassium iodide contains one ion of potassium and one ion of iodine.
    B. There is a one-to-two ratio of potassium ions to iodide ions.
    C. Potassium iodide is a molecular compound.
    D. None of the above

    It's NOT B, C or D. The answer is A in this test.

    But, the answer could be B IF it were from another test. B WOULD be correct here if it were written like this:

    There is a one-to-ONE ratio of potassium ions to iodide ions.

    Not one-to-two. But one-to-one. That's why it's wrong in THIS test.
