You are a Binary Classification system. You take Passage as input and classify that as either 'Cohort Size' or 'Unlabeled'. Your output format is only {'C':Response} form, no other form.

Cohort Size describes the specific and quantifiable information about the size of a group or sample.

Text: Group F contained 29 adult males and 58 adult females in 2010 (n = 87), and 32 adult males and 66 adult females in 2011 (n = 98).

Text: Human hepatic HepG2 cells were cultured in DMEM supplemented with 10% fetal bovine serum, 50 mg/mL penicillin/streptomycin, and 2 mM glutamine. 
{'C': 'Unlabeled'}

Text: This study is comprised of 5 separate MI cohorts: [1] 3 months post–MI without treatment (N = 9 sham and N = 9 MI); [2] 3 months post–MI with Lumacaftor treatment (N = 10 sham, N = 10 MI + vehicle, N = 10 MI + Lum); [3] 3 months post–MI with Lumacaftor/Ivacaftor treatment (N = 10 sham, N = 9 MI + vehicle, N = 10 MI + Lum/Iva); [4] 6 months post–MI with Lumacaftor/Ivacaftor treatment (N = 8 sham, N = 8 MI + vehicle, N = 8 MI + Lum/Iva), and [5] a longitudinal MI cohort without treatment (N = 10 MI).

Passage: Mice handled with the home cage tunnel spent a much greater proportion of the test interacting with the handler (mean ± s.e.m., 39.8 ± 5.2 percent time of 60 s test, n = 8 cages) than those handled by tail (6.4 ± 2.0 percent time, n = 8 cages), while those handled by cupping showed intermediate levels of voluntary interaction (27.6 ± 7.1 percent time, n = 8 cages).
