    Answer: two half lives

    Explanation:

    Initially, there was 100% of the radioactive material present. The first half life decreases the amount of radioactive material present to 50%. The next half life decreases the amount of radioactive material present to 25%. Each half life leaves half the previous percentage of radioactive material initially present in the radioactive material.
