    I will be writing my final exam tomorrow evening, and I am currently stuck on the following practice problem. It would be very nice if someone could help me out and I will remain eternally grateful for your help!

    1) (Multiple Choice) Which of the following statement(s) about Cold Dark Matter (CDM) is (are) incorrect:
    a) CDM particles travel at a speed much lower than c
    b) neutrinos are a candidate for CDM
    c) simulation models using CDM produce smaller scale structures than those using Hot Dark Matter
    d) CDM is likely baryonic
    e) CDM particles should be more massive than HOT Dark Matter particles


    Well, I believe that a and e are true, b and d are false, but I am totally unsure about c...is it true or false and why? Does anyone know?

    Thank you!
