why was my answer marked as wrong? The question was ''what is the primary CO2 chemosensing organ in the body that drives respiration?'' my answer was ''the vestibular hair cells in the inner ear''. I gave a link to mouse study as proof.

This was the link

https://www.ncbi.nlm.nih.gov/pubmed/21130842

It seems pretty clear cut to me they are implying the inner ear is a primary chemosensing organ and another paper on the same subject said there was a 53% loss in CO2 ventilatory drive which makes the inner ear the primary chemosensing organ while the carotid bodies and the medulla play a much smaller role. So why was my answer marked as being wrong?
