8. In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair 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 on the walls.
(C) because tourists were exhaling moisture, which had raised the humidity within them 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
OG 13 explain C D: them seems to refer to tourists
but E is correct
I think the C explain it that the tourists is close to them and the tourists is a subject. so them refer to tourists.
But I am confused that D and E the tourists is not a subject. and the D E have the similar structure. why the D's explain that them refer to tourists???
