Answer to Question 1

The planet's rotation, as the word dynamo implies, is paramount in generating the magnetic field, so the field should align itself with the rotational axis; in other words, the N needle on a compass should really point north. For Saturn, it is fine, but at Earth and Jupiter, the field is off by about 10 degrees. However, for Uranus this magnetic tilt is 59 degrees, and even for Neptune it is 47 degrees off. Also, the core of the planet should contain the electrically conductive fluid that generates the field, but for both green giants, the fields do not pass anywhere close to this core.

Answer to Question 2

B

Astigmatism is the most common vision problem. It may accompany nearsightedness or farsightedness. It is usually caused by an irregularly shaped cornea, but sometimes it is the result of an irregularly shaped lens. Either type can be corrected by eyeglasses, contact lenses, or refractive surgery.
