Q: Answer the following question given this paragraph: Earth's magnetic poles have switched places repeatedly in the past. As you can see in the Figure below , each time the switch occurred, Earth's magnetic field was reversed. The magnetic field is the region around a magnet over which it exerts magnetic force. We think of today's magnetic field direction as "normal," but that's only because it's what we're used to. You can watch a simulation of a magnetic field reversal at this URL: http://www. pbs. org/wgbh/nova/earth/when-our-magnetic-field-flips. html. Q: The earth's magnetic poles have done what repeatedly in the past? Choices: - rotated - stayed the same - demagnetized - switched places A:
A: switched places

Answer the following question given this paragraph: Radioisotopes are widely used in medical diagnosis. These isotopes need to have short half-lives so that they can be administered in very low doses, thus minimizing damage to cells. Q: What type of isotopes have short half-lives and are given in very low doses? Choices: - stable isotopes - gasses - radionuclides - radioisotopes A:
**Answer**
radioisotopes
