We determined the structure function ratio REMCᵈ=F₂ᵈ/(F₂ⁿ+F₂ᵖ) from recently published F₂ⁿ/F₂ᵈ data taken by the BONuS experiment using CLAS at Jefferson Lab. This ratio deviates from unity, with a slope dREMCᵈ/dx=-0.10±0.05 in the range of Bjorken x from 0.35 to 0.7, for invariant mass $W>1.4$ GeV and Q²>14pt0exGeV². The observed EMC effect for these kinematics is consistent with conventional nuclear physics models that include off-shell corrections, as well as with empirical analyses that find the EMC effect proportional to the probability of short-range nucleon-nucleon correlations.
