Task: Class Definition Understanding (ontology: Food_Agriculture/Crop_Ontology)

Which of the following definitions best describes 'Duration between 5 and 95% senescence of subplot - Computation'?

A. Computation of the substraction between the necessary time before 95% and 5% emergence using after-fitting inverse regression of log-logistic time-to-event modeling of weekly sprout counts expressed in days after planting
B. Computing the number of days required from first sprout emergence to first flower initiation
C. Compute number of growing degree days required from planting (or 50% emergence) to 50% foliage senescence or maturity.
D. Averaged senescence period duration expressed in days between 5 and 95% senescence (i.e. 95%  and 5% of maximum ground cover after time to maximum ground cover) in two subplots.
Ground cover computed from weekly images analysis. 
Time at 95% and 5% of maximum growth after time at maximum growth computed via inverse regression of time to event Beta ground cover dynamic model.

Answer: Averaged senescence period duration expressed in days between 5 and 95% senescence (i.e. 95%  and 5% of maximum ground cover after time to maximum ground cover) in two subplots.
Ground cover computed from weekly images analysis. 
Time at 95% and 5% of maximum growth after time at maximum growth computed via inverse regression of time to event Beta ground cover dynamic model.
