Claiming and denying

Jones puts forward an interesting theory¹ of language learning, backing up² his argument with thorough data. Fully accepting the fact that different learners find different methods useful, Jones makes the point³ that motivation is the key factor in most learners’ success. Although this has been widely acknowledged⁴ in general terms for some time, Jones is more precise than most, stating clearly that motivation is more important than all other factors, and substantiating⁵ this claim with impressive data.
