Options A and B are not correct because “should” and “would” do not reflect the command in order to maintain the meaning of the sentence. Should and would suggest that the it is at the discretion of the state to abolish the literacy test, which is not the case here.

E and D are also incorrect because the use of “abolishing of” does not appropriately reflect the requirement by the Act. An infinitive is appropriate.

C is correct as it rightly use the infinitive form of the verb to reflect the requirement or command in the Act. The use of “to abolish” is correct here and correctly reflect the meaning of the sentence.

"Among the triumphs of the era were Civil Rights, 24th Amendment and Voting Rights, which ORDERED the state TO abolish…"
We need to show intent, thus "to abolish"; the other choices have verb tense errors or unintended meanings.

Answer (C)

Among the eras triumphs were the Civil Rights Act of 1964, barring segregation in public places; the 24th Amendment to the Constitution, ratified in 1964, prohibiting the poll tax; and the 1965 Voting Rights Act, which ordered the state should abolish literacy tests as a requirement for registering to vote.

The sentence has a list of three items
- Civil Rights Act of 1964
- 24th Amendment to the Constitution, ratified in 1964
- the 1965 Voting Rights Act

and each of the items is provided with brief detail. As per the third the state was ordered to abolish literacy where ‘ordered’ is the verb – a commanding verb and ‘should abolish’ is the Voting Rights Act’s intention. Observing the answer choices there’re no other differences among them.

A. should abolish literacy tests as a requirement for registering to vote. – WRONG. A helping verb ‘should’ doesn’t communicate intention.
B. would abolish literacy tests as a requirement for registering to vote. – WRONG. Same as option ‘A’.
C. to abolish literacy tests as a requirement for registering to vote. – CORRECT. ‘To + Verb’ s used for intentional purpose.
D. abolishing of literacy tests as a requirement for registering to vote. – WRONG. Verb+ing form of abolish with a prepositional phrase is not used for communicating intention.
E. the abolishing of literacy tests as a requirement for registering to vote – WRONG. Here ‘the’ is added to option D however it’s still not error free.

IMO Answer (C).

It has got to be C. which ordered the state "to" abolish. Using the order for the verb abolish.

Official Explantion

Correct Answer: C
