Choose the appropriate preposition to complete the sentence.

The curator removed a rare coin _______ the display case.

The correct option is from.

Step-by-Step Explanation:
A preposition is a word used to connect nouns or pronouns with other words in a sentence, indicating relationships of time, direction, place, or origin. In the given sentence, the verb "removed" describes an action where an item (a rare coin) is being taken out of or separated from its original location (the display case).

Let's evaluate each option to see which preposition fits grammatically and contextually:

1. from: This preposition is used to indicate origin, source, or the starting point of removal. The structure "remove something from a place" is the standard phrase used to express taking an object out of a container or setting. Therefore, this is the correct choice.
2. between: This preposition indicates a position or space separating two or more distinct entities (e.g., "between two tables"), which does not make sense in the context of removing a single object from a location.
3. across: This preposition describes movement from one side of a surface or area to another (e.g., "across the room"), which does not describe taking an item out of a case.
4. along: This preposition indicates movement following the length or direction of a path or line (e.g., "along the road"), which is contextually incorrect here.

Therefore, the complete sentence is:
"The curator removed a rare coin from the display case."
