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

Text: The study design included four groups of female C57BL/6N mice (n=80; 20 per group)
{'C': 'Allocation'}

Text: Special care was used to limit animal discomfort throughout the whole study.
{'C': 'Unlabeled'}

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 resulted in sample size of 6 animals/group, which is conform with the housing and handling capacity under BSL3 conditions at the Rega Institute.
{'C': 'Allocation'}

Text: Twelve weeks old male C57BL/6JGpt mice were randomly divided into three groups (n = 6 for each).
{'C': 'Allocation'}

Text: Mice were dissected at 5 dpi to collect the cortex, hippocampus, thalamus, lung, and kidney to screen for virus loads, histopathological changes, and proteomic and phosphoproteomic profiling.
{'C': 'Unlabeled'}

Text: We calculated that 7–15 mice per treatment group would be able to detect a 30% reduction in arthritis scores with an 80%–93% power, and a p ≤ 0.05.
{'C': 'Allocation'}

Passage: Eight 10-week-old K18-hACE2 mice were equally divided into virus-infected (n = 4) and control (n = 4) groups.
