Two meanings with the same pronunciation
A fictional student edits two sentences for a school newsletter. The first is 「新しい地域の調査に、カンシンを持った。」 The second is 「仲間の粘り強い努力に、カンシンした。」 The surrounding notes explain that the first writer became interested and wanted to learn more, while the second writer admired the effort. These notes are part of the exercise and remove the ambiguity that a bare pronunciation could create. The student must select suitable characters, then explain the contrast in meaning rather than claiming that identical sounds always require identical spelling. A third draft says 「私の目標は、本を紹介したい。」 It is included to ask about the logical fit between the opening topic and the final predicate, not to impose a particular career or school role.
