What would happen to the core of the sun if its temperature rose slightly?
A) The rate at which fusion occurs would increase, leading to a contraction of the core, which would in turn cause the temperature to rise even further.
B) The rate at which fusion occurs would decrease, leading to a contraction of the core, which would in turn cause a further temperature rise.
C) The rate at which fusion occurs would decrease, leading to an expansion of the core, which would in turn cause the temperature to drop back down.
D) The rate at which fusion occurs would increase, leading to an expansion of the core, which would in turn cause the temperature to drop back down.
Question 2
In addition to the conditions required for any solar eclipse, what must also be true in order for you to observe a total solar eclipse?

B) The Moon's umbra must touch the area where you are located.
C) Earth must lie completely within the Moon's umbra.
D) Earth must lie completely within the Moon's penumbra.
E) The Moon's penumbra must touch the area where you are located.
