The discovery that Earth’s inner core rotates independently of and more quickly than
Earth’s outer layers is responsible for advancing studies of the flow of heat from the inner
through the outer planet and of the formation and periodic reversal in direction of Earth’s
magnetic field.
A. core rotates independently of and more quickly than Earth’s outer layers is
responsible for advancing studies of the flow of heat from the inner through the
outer planet and of the formation and periodic reversal in direction of Earth’s
magnetic field
B. core rotates independently of and more quickly than Earth’s outer layers is
responsible for advancing studies of how heat from the inner core flows through
the outer planet, and the formation and periodic reversal in direction of Earth’s
magnetic field
C. core rotates independently and more quickly than Earth’s outer layers are
responsible for advancing studies of how heat from the inner core flows through
the outer planet, and how Earth’s magnetic field forms and the periodic reversal
of its direction
D. core, rotating independently and more quickly than Earth’s outer layers, are
responsible for advancing studies of the flow of heat from the inner through the
outer planet, and the formation and periodic reversal in direction of Earth’s
magnetic field
E. core, rotating independently of and more quickly than Earth’s outer layers, is
responsible for advancing studies of the flow of heat from the inner through the outer planet and of how Earth’s magnetic field forms and the periodic reversal of
its direction
OA: a
Please explain the construction of the statement : ' core rotates independently of and more quickly than Earth’s outer layers is
responsible for advancing studies of the flow of heat from the inner through the
outer planet and of the formation and periodic reversal in direction of Earth’s
magnetic field'

Discovery is so A B and E.
In E - , rotating independently of and more quickly than Earth’s outer layers, should be part of main clause - out
B-advancing studies of how heat from the inner core flows through
the outer planet - wrongly placed
A -wins.
In E - , rotating independently of and more quickly than Earth’s outer layers, should be part of main clause - out
B-advancing studies of how heat from the inner core flows through
the outer planet - wrongly placed
A -wins.
Can you explain what you mean by "wrongly placed"? Thanks.hemantsood wrote: B-advancing studies of how heat from the inner core flows through

A -wins.
I also picked "A", but only because I saw two errors in "B". "B" unnecessarily creates a final clause by using a comma, and the final clause is not parallel because it omits "of".

Should be how heat flows from the inner core to the outer planet instead of how heat from the inner core flows through the outer planet.ken3233 wrote:Can you explain what you mean by "wrongly placed"? Thanks.hemantsood wrote: B-advancing studies of how heat from the inner core flows through

I was in hurry last time when I wrote wrongly placed I should have written more precisely.

A. core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies
of the flow of heat from the inner through the outer planet and
of the formation and periodic reversal in direction of Earth's magnetic field
S-V agreement is perfect [The discovery_______is_______]
The discovery _____ is responsible for advancing studies of ______ and (study) of __________ Correct ||'sm is maintained.
B. core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies
of how heat from the inner core flows through the outer planet, and
the formation and periodic reversal in direction of Earth's magnetic field
"and" is unable to maintain ||'sm here.
C. core rotates independently and more quickly than Earth's outer layers are responsible for advancing studies
of how heat from the inner core flows through the outer planet, and
how Earth's magnetic field forms and the periodic reversal of its direction
SV agreement and
||sm error
D. core, rotating independently and more quickly than Earth's outer layers, are responsible for advancing studies
of the flow of heat from the inner through the outer planet, and the formation and periodic reversal in direction of Earth's magnetic field
E. core, rotating independently of and more quickly than Earth's outer layers, is responsible for advancing studies
of the flow of heat from the inner through the outer planet and
of how Earth's magnetic field forms and the periodic reversal of its direction
rotating(Verb+Ing) is problematic in D and E. It misleads as if the discovery is rotating.
I would like to discuss more on the ||'sm issue in D and E.

D has subject verb agreement error. Other than that the parallelism seems to be ok.richachampion wrote:A. core rotates independently of and more quickly than Earth's outer layers is responsible for advancing studies

E is clearly not parallel --
core, ___, is responsible for advancing studies of the flow of heat from the inner through the outer planet and
of how Earth's magnetic field forms and the periodic reversal of its direction
