2. ...calculated that the internal solar magnetic fields could produce instabilities in the solar plasma.
3. ...holds that Milankovitch cycles can induce changes in solar heating on Earth and the changes are amplified on Earth.
4. ...doesn\'t believe in Ehrlich\'s viewpoints at all.

In boxes 5-9 on your answer sheet write
TRUE if the statement is true according to the passage

7. Carbon dioxide can be locked artificially into sea ice to eliminate the greenhouse effect.

A British scientist, however, challenges this view by claiming that the internal solar magnetic ...12... can induce the temperature oscillations in the sun\'s interior. The sun\'s core temperature oscillates around its average temperature in ...13... lasting either 100,000 or 41,000 years. And the ...14... interactions within the sun\'s magnetic field could flip the fluctuations from one cycle length to the other, which explains why the ice ages changed frequency a million years ago.
