Question from Solar Flares' Article

Questions:
1. What is Solar Flares?
    a. The high magnetic fields in the sunspot-producing active regions that
         also give riese to explosions
    b. The high temperature fields in the sunspot-producing active regions
         that also give riese to explosions
    c. The high land in the sunspot-producing active regions that
         also give riese to explosions
    d. The high magnetic fields in the sunspot-producing active regions that
         also give a massive light
    e. Temperatures in the outer layer of the sun
2. Did Sunspots appear in random locations? Why?
    a. Yes, because they are moving
    b. Yes, because they are big
    c. No, because they tend to be concentrated in two mid-latitude bands on
        either side of the equator
    d. No, because they are not moving
    e. Yes, becuase they did not tend to be concentrated in two mid-latitude
        bands on either side of the equator
