Directions: Choose the pair(s) of words that need to be interchanged to make…

Concept: In an “interchange of words” question, one or more pairs of words must be swapped so that every verb-object and noun-preposition pairing in the sentence follows a standard collocation and the sentence reads as one logically complete statement. A swap is valid only when it removes every mismatched pairing at once — fixing one pairing while leaving another broken does not resolve the sentence.

Application: The marked words in the given sentence are solved (A), remedies (B), asked (C), and problem (D), in the order: “The Justice Officer solved (A) whether every judicial remedies (B) could be asked (C) through constitutional problem (D).”

1. Read the sentence in its original order: it produces the phrases “solved whether” and “remedies could be asked” and “constitutional problem.” A “whether” clause is not typically paired with “solved,” and “remedies” is not typically paired with “asked” as its subject.

2. Interchange A and C (solved ↔ asked): the opening clause becomes “The Justice Officer asked whether …,” giving the standard pairing “asked whether.”

3. Interchange B and D (remedies ↔ problem): the second clause becomes “… every judicial problem could be solved through constitutional remedies,” giving the standard pairings “problem could be solved” and “through constitutional remedies.”

4. Applying both interchanges together gives: “The Justice Officer asked whether every judicial problem could be solved through constitutional remedies” — every pairing in the sentence now follows a standard collocation, and the sentence reads as one complete statement.

Cross-check: Testing each interchange alone shows neither removes every mismatch by itself: interchanging only A and C still leaves “remedies could be asked … constitutional problem,” where “remedies” is still paired with “asked”; interchanging only B and D still leaves “solved whether every judicial problem,” where “solved” is still paired with a “whether” clause. Only interchanging both A-C and B-D together removes every mismatched pairing in the sentence.
