Find the correct combination of the words that should replace each other to make both sentences contextually meaningful.
(I) The park was dismayed (A), and we adored (B) walking around and taking in the reparation(C);
(II) we were sublime (D) to find out that the main attraction (E) was closed for scenery (F).

To find the correct combination of words that need to be swapped to make both sentences grammatically and contextually meaningful, let us analyze the context of each sentence step-by-step:

Sentence (I): "The park was dismayed (A), and we adored (B) walking around and taking in the reparation (C);"
- A park is an inanimate object and cannot feel "dismayed" (A). Thus, (A) is contextually incorrect in this position.
- The phrase "adored (B) walking around" makes perfect sense as "adored" means loved or enjoyed very much.
- "taking in the reparation (C)" is incorrect because "reparation" means making amends for a wrong one has done, which does not fit the context of a park's visual surroundings. We typically take in the "scenery" of a park.

Sentence (II): "we were sublime (D) to find out that the main attraction (E) was closed for scenery (F)."
- Humans can feel "dismayed" (distressed or disappointed) upon finding out that a main attraction is closed. Placing "dismayed" in position (D) makes perfect sense: "we were dismayed to find out...". Similarly, describing a park as "sublime" (of such excellence or beauty as to inspire great admiration) in position (A) makes perfect sense: "The park was sublime...". Thus, swapping (A) and (D) resolves these context errors.
- "main attraction (E)" is contextually correct, as attractions can be closed for maintenance or repairs.
- "closed for scenery (F)" is incorrect, but swapping it with "reparation (C)" makes both sentences correct: "taking in the scenery (F)" in sentence (I) and "closed for reparation (C)" (meaning closed for repairs/restoration) in sentence (II).

By swapping (A) with (D) and (C) with (F), we get the following fully meaningful sentences:
- Sentence (I): "The park was sublime, and we adored walking around and taking in the scenery;"
- Sentence (II): "we were dismayed to find out that the main attraction was closed for reparation."

Therefore, the correct combination of words to replace each other is (A)- (D) and (C)- (F).
