What allows a high-mass star to fuse different elements from a low-mass star?
A. Its greater mass means that it contains more elements.
B. More mass means a stronger magnetic field that helps heavier elements fuse.
C. High-mass stars spin slower and thus do not mix their fuels as well.
D. More mass means more compression and thus a hotter core that allows heavier elements to fuse.
E. The statement is false. Low-mass and high-mass stars can fuse the same elements.

Two identical concentric loops are arranged as shown in the diagram below. Loop 1 initially carries a steady current driven by the power supply shown, will the two loops briefly attract or repel each other as the current in loop 1 decays to zero? 
Suppose that when we turn off the power supply, it takes a small but finite time for the current to decay to zero in loop 1. In what direction does the current induced in loop 2 flow during this time interval?
A. They attract each other. B. They repel each other. C. They neither attract nor repel each other. D. One needs more information to answer.
