Why might the following nuclear reaction not be very good for energy production in a fission reactor?
U ? 
Ba + 
Kr + 1 neutron
A. The mass of the by-products is too high and therefore the energy released will not be high enough.
B. The material only produces one neutron so the chain reaction will not be very efficient.
C. Interatomic attraction between the products will impede the efficient separation of the atoms from the unstable nuclei.
D. There are too many products produced.
E. The products are too large.

It is theorized that a pulsar only emits X-rays and visible light during its early history. What do you suppose is the basis of this theory?
A) As the pulsar's energy dissipates, the frequency of the energy it emits drops. B) X-rays are likely the result of radioactive decay, which only can occur in a pulsar's early history. C) X-rays and visible light are both part of the electromagnetic spectrum. D) The pulsar's high rate of spin produces a magnetic field that, over time, slows the pulsar down.
Along divergent plate boundaries, magma formation takes place typically due to:
a) melting of the plates as they move apart as a result of frictional heating b) increased pressure from plate movement c) pressure being reduced (decompression melting) as the plates move apart d) water being released under pressure which lowers the melting temperature of the overlying asthenosphere e) hot spots, which always occur along divergent boundaries
