I do a park's walk every morning. [Syntax]

The correct answer is "さんぽ" (sanpo). This noun means "walk." When combined with the verb "します" (shimasu, to do) and the particle "を," it forms the phrase "さんぽをします" (sanpo o shimasu), meaning "to take a walk." "こうえん" (kouen) is the noun for "park." "の" (no) is a particle that connects nouns, here indicating a "park's walk" or "walk in the park." "を" (o) is the direct object particle, which should follow "さんぽ."

正解は「さんぽ」です。動詞「します」と助詞「を」と共に「さんぽをします」で「散歩する」という意味になります。「こうえん」は名詞で、「の」は名詞と名詞をつなぐ助詞です。「を」は目的語を示す助詞で、「さんぽ」の後に続きます。
