    I agree with both of your answers.

    C is possibly the first answer, it would depend on that the Dr is studying. Lagged cross-coorelation coefficents look for delayed reactions in one twin due to a change in the other. Two years is a hint, but not conclusive.

    B is correct on the second.

  • psychology -

    D is definitely the correct answer for the first question. The case study method follows individuals for a prolonged period of time — a longitudinal study. Two years would qualify as a long period of time.

    You are right with the second question. Down syndrome is caused by a trisomy (an extra chromosome) of chromosome 21.

    I hope this helps a little more. Thanks for asking.
