Which example illustrates a correct modifier placement?

The example that illustrates a correct modifier placement is when the adverb "quickly" is used to describe how the man ran. In this case, the placement of "quickly" before the verb "ran" provides clarity and enhances the meaning of the sentence by specifying the manner of the action. This arrangement allows readers to easily understand that it is the running that is performed quickly by the man.

In contrast, the other examples suffer from either awkwardness or incorrect structure. For instance, placing the adverb before the noun, as in "The quickly man ran to the store," disrupts the sentence flow and makes it unclear, as adverbs do not typically modify nouns. The third choice, "The man ran quickly to the store," is also correct, but does not serve as the best example compared to the other options. Finally, stating "The store ran quickly to the man" creates confusion, as it attributes human qualities to an inanimate object, which is illogical and grammatically incorrect.
