Stars like the sun can continue to shine steadily for billions of years because its light and heat are produced by nuclear fusion, in which titanic releases of energy result in the loss of only tiny amounts of mass.
(A)
its light and heat are produced by nuclear fusion,
in which(B)
nuclear fusion produces its light and heat,
in which(C)
nuclear fusion produces their light and heat,
where(D)
its light and heat are produced by nuclear fusion,
where(E)
their light and heat are produced by nuclear fusion,
in which
we can notice two kinds of splits in our 5 second scan!
1)its/their/nuclear fusion- probably pronoun agreement
2)in which vs where- probably modifier errorlets analyse split #2:
"where" can only modify places and nuclear fusion/ heat/light do not qualify as places therefore we can
eliminate options C and Dlets analyse split 1:
its illogically refers to stars! therefore we can
eliminate options A and Btherefore E is the correct option!option wise analysis:
(A)
its light and heat are produced by nuclear fusion, in which
(B) nuclear fusion produces
its light and heat, in which
(C) nuclear fusion produces their light and heat,
where(D) its light and heat are produced by nuclear fusion,
where(E) their light and heat are produced by nuclear fusion, in which-
Correct!
