  5. i got you guys, just took the test. heres the right answers;
    1. the GRAVITY of dark matter causes baryonic gas and dust to CLUMP TOGETHER.
    2. according to measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP), which material is by far the most plentiful in the universe? DARK ENERGY
    3. which types of baryonic matter are most abundant in the universe? Select the two correct answers. HYDROGEN AND HELIUM
