885-sec1-9 V+ing与which指代全句

9.     As the price of gasoline rises, which makes substituting alcohol distilled from cereal grain attractive, the prices of bread and livestock feed are sure to increase.

(A) which makes substituting alcohol distilled from cereal grain attractive

(B) which makes substituting the distillation of alcohol from cereal grain attractive

(C) which makes distilling alcohol from cereal grain an attractive substitute

(D) making an attractive substitution of alcohol distilled from cereal grain（E）

(E) making alcohol distilled from cereal grain an attractive substitute

我的问题: OG有道题说V+ing的句子不能放在两句中间, 因为无法分辩是修饰哪句的. 另外, which不能指代前面的全句. 这时哪个优先考虑? 谢谢!

你说的那题可能是OG21吧

21. Defense attorneys have occasionally argued that their clients' misconduct stemmed from a reaction to something ingested, but in attributing criminal or delinquent behavior to some food allergy, the perpe­trators are in effect told that they are not responsible for their actions.

(A)  in attributing criminal or delinquent behavior to some food allergy

(B)  if criminal or delinquent behavior is attributed to an allergy to some food

(C)  in attributing behavior that is criminal or delinquent to an allergy to some food

(D)  if some food allergy is attributed as the cause of criminal or delinquent behavior

(E)  in attributing a food allergy as the cause of criminal or delinquent behavior

In choices A, C, and E, in attributing ... behavior modifies the perpetrators, producing the illogical statement that the perpetrators rather than the defense attorneys are attributing behavior to food allergies. Choice C is also wordy, and attributing ... as is unidiomatic in E. In the correct form of the expression, one attributes x, an effect, to y, a cause; or, if a passive construction is used, x is attributed to y. D avoids the initial modification error by using a passive construction (in which the attributors are not identified), but attributed x as the cause of y is unidiomatic. Choice B is best.

GMAT中which不能指代句子是个绝对的真理，所以，碰到which指代句子的必错；其实，现分在句中造成修饰混乱的现象大都出现在语法修饰对象和逻辑修饰对象不一致，比如OG21中in attributing的语法修饰对象是perpetrators，而逻辑修饰对象应该是attorneys；而你所举的这个例子没有这个问题，making很明显是跟主句，表明rises这个动作的后果。

谢谢. 我不是指OG21,还有其他的句子, 我一时还记不起来.
