My try:
In late 1997, the chambers inside the pyramid
of the Pharaoh Menkaure at Giza were closed
to visitors for cleaning and repairing
due to moisture exhaled by tourists, which raised its humidity
to such levels so that salt from the stone was crystallizing and fungus was growing in the walls.
A.
due to moisture exhaled by tourists, which raised its humidity
to such levels so that salt from the stone was crystallizing
B.
due to moisture that tourists had exhaled, thereby raising its humidity
to such levels that salt from the stone would crystallize
C.
because tourists were exhaling moisture, which had raised the humidity within then
to levels such that salt from the stone would crystallize
D.
because of moisture that was exhaled by tourists raising the humidity within them
to levels so high as
to make the salt from the stone crystallize
E.
because moisture exhaled by tourists had raised the humidity within them
to such levels that salt from the stone was crystallizing
The way I understand it (cutting the flab...)
Chambers were closed for...(why?)
BECAUSE high level
of moisture had raised the humidity
to a level that salt from the stone was
crystallizing and fungus was
growing in the walls.
EA:
1) Chambers were closed
DUE TO... (were closed clause in the non underlined section...)
DUE TO is wrong... has
to be replaced by
BECAUSE OF...
2)
due to (->
BECAUSE OF) is followed by moisture {exhausted by... modifier} NOT logical. It must be followed by the reason why the chambers were closed...
because "high levels
of humidity..... that salt from the stone was crystallizing and fungus was growing in the walls"
3) Right choice must contain "
crystallizing" In the clause "that salt from the stone was
crystallizing and fungus was
growing in the walls"
to maintain the parallelism.
POE:
1)
DUE TO scan: A and B are gone
2)
Because of must be followed by the reason: C is gone
3) crystallizing/crystallize: Except A and E all violate this -> D is also gone
E is the correct answer.

It seems likely that a number
of astronomical phenomena, such as the formation
of planetary nebulas, may be caused by the interaction where two stars orbit each other at close range.
A. may be caused by the interaction where two stars orbit each other
B. may be caused by the interaction between two stars that each orbit the other
C. are
because of the interaction between two stars that orbit each other
D. are caused by the interaction
of two stars where each is orbiting the other
E. are caused by the interaction
of two stars orbiting each other
The way I understand it (cutting the flab...)
- It seems likely
- that a number
of astronomical phenomena, {such as the formation AP},
are caused by the interaction
in which two stars orbit each other at close range.
EA:
A possibility has been presented.
Lets take an example:
It is
likely that something
is true.
It is
likely that something
may be true.
In the above two sentences, second is wrong. Why?
Because use
of "may be" with likely already being said for the same purpose is redundant.
So, 1) may be MUST get replaced by ARE
2) 'may be caused by' is supposed
to and is modifying "astronomical phenomena". So "
Because of" cannot be used in its pace..."
because of" might come in...(in that case following phrase has
to be modifies accordingly)
3) Where can only refer
to a physical place (country, place, city etc.) not
to a situation
So, IN WHICH must be used
POE:
1) LIKELY (non-underlined)/MAY BE: A and B are gone
2) use
of "
because of": C is gone
3) use
of "where": A and D are gone (A twice
)
Left with E !
I am not going for seeing meaning
of those answers I have already marked wrong!
Happy
to be get corrected on my misunderstanding!
