og-175-ETS V.S. XDF?

175. Two new studies indicate that many people become obese more due to the fact that their bodies burn calories too slowly than overeating.

(A) due to the fact that their bodies burn calories too slowly than overeating

(B) due to their bodies burning calories too slowly than to eating too much

(C) because their bodies burn calories too slowly than that they are overeaters

(D) because their bodies burn calories too slowly than because they eat too much（D）

(E) because of their bodies burning calories too slowly than because of their eating too much

解释第六行说E的because of their bodies burning calories too slowly than ... 中的bodies 要改成bodies' 即变成bodies' burning 才行，但one's doing不是一定错的吗(新东方语），是否说明ETS承认one's doing 也有对的时候？

ONE'S DOING不是一定错，语法书中有详细解释~~

但这道题不是这样解，重点是MORE...THAN的用法，MORE后面和THAN后面要平行，不论用DUE TO还是用BECAUSE还是用BECAUSE OF,都要平等，如MORE DUE TO... THAN DUE TO...，不选E是因为E远不如D简洁，而ABC MORE...THAN前后都不平行
