还是关于OG解释的疑问

12.   Traveling the back roads of Hungary, in 1905 Béla Bartók and Zoltán Kodály began their pioneering work in ethnomusicology, and they were armed only with an Edison phonograph and insatiable curiosity.

(A) Traveling the back roads of Hungary, in 1905 Béla Bartók and Zoltán Kodály began their pioneering work in ethnomusicology, and they were armed only

(B) In 1905, Béla Bartók and Zoltán Kodály, traveling the back roads of Hungary, began their pioneering work in ethnomusicology, and they were only armed

(C) In 1905 Béla Bartók and Zoltán Kodály began their pioneering work in ethnomusicology, traveling the back roads of Hungary armed only

(D) Having traveled the back roads of Hungary, in 1905 Béla Bartók and Zoltán Kodály began their pioneering work in ethnomusicology; they were only armed（C）

(E) Béla Bartók and Zoltán Kodály, in 1905 began their pioneering work in ethnomusicology, traveling the back roads of Hungary, arming themselves only

正确答案：C。 armed only 用来修饰B and K ，而它的位置不会产生歧义吗？

19.   The commission acknowledged that no amount of money or staff members can ensure the safety of people who live in the vicinity of a nuclear plant, but it approved the installation because it believed that all reasonable precautions had been taken.

(A) no amount of money or staff members

(B) neither vast amounts of money nor staff members

(C) neither vast amounts of money nor numbers of staff members

(D) neither vast amounts of money nor a large staff（D）

(E) no matter how large the staff or how vast the amount of money

In choice A, amount of … staff members is incorrect; amount properly refers to an undifferentiated mass, as in the case of money. Choice B does not make clear whether vast amounts is supposed to describe money only or money and staff members, and in choice C it is not certain whether vast modifies amounts only or amounts and numbers. Choice D is best. Choice E cannot fit grammatically into the original sentence because it supplies no noun that can function as a subject for the verb can. This question is a little more difficult than the average.

对B选项的解释不理解，我认为可以明确amounts of 仅修饰money。
