Neither a rising standard of living nor balanced trade,
by itself, establishes a country's ability to compete in
the international marketplace. Both are required
simultaneously since standards of living can rise
because of growing trade deficits and trade can be
balanced by means of a decline in a country's
standard of living.

If the facts stated in the passage above are true, a
proper test of a country's ability to be competitive is
its ability to

(A) balance its trade while its standard of living rises
(B) balance its trade while its standard of living falls
(C) increase trade deficits while its standard of living
rises
(D) decrease trade deficits while its standard of
living falls
(E) keep its standard of living constant while trade
deficits rise

Why the answer choice E & B is wrong. anyone pls explain
