There is an exercise problem in my workbook:
木村さん:明日は奈良を案内しますよ。
張さん:ありがとうございます。
Four options are provided (I only list the two that I find confusing):
1.張さんは木村さんに奈良を案内してもらいます。
4.木村さんは張さんに奈良を案内してくれます。
and one is asked to choose the one that has the same meaning as the dialogue. The answer given is the 1st one, but I chose the 4th one and still don't know why it's wrong.
