A) Exposure to air pollution may amplify the risk of developing blood clots; one reason is suggested by the finding that small particulates that enter the bloodstream from the lungs cause blood cells to coagulate more readily.
Perhaps the best among the choices, though - the expression one reason is suggested by the finding - looks a little odd.
(B) Entering the bloodstream from the lungs, one reason that exposure to air pollution may amplify the risk of developing blood clots is suggested by the finding that small particulates cause blood cells to coagulate more readily.
Entering the bloodstream – one reason -MM
(C) Entering the bloodstream from the lungs, one reason exposure to air pollution may amplify the risk of developing blood clots is suggested by the finding that small particulates cause blood cells to coagulate more readily.
Entering the bloodstream – one reason -MM (D) The finding that small particulates cause blood cells to coagulate more readily is suggestive of one reason, entering the bloodstream from the lungs; exposure to air pollution may amplify the risk of developing blood clots.
What is -
entering the bloodstream from the lungs -modifying? -
One reason? Or - The finding? - A total mess, missing the meaning way off the mark
(E) The finding of small particulates entering the bloodstream from the lungs and causing blood cells to coagulate more readily suggests one reason exposure to air pollution may amplify the risk of developing blood clots from blood cells
_
The finding of small particulates entering the bloodstream- Is the finding entering the blood stream ?– absurd
A is the only acceptable choice
