Translation:I will study Chinese even harder.
I saw this answer as well. The correct answer was, "I will put more effort into learning Chinese." my answer was, "I will put more effort into studying Chinese." I feel like studying and learning should both be accepted answers.
...and even more into learning the English that Duolingo expects in translation.
I will make studying Chinese even harder by (exclusively) using Duolingo. ;-p
I will put more effort in learning Chinese should be accepted. Give Lingot = Agree
