Structure of the base table

Consider the predictive modeling problem where you want to predict whether a candidate donor will make a donation in the next year. To build the model, you use historical data and calculate the target in 2017. The target is 1 if a donation is made in 2017 and 0 otherwise. Below, the first lines of the base table are given. It contains the number of donations made in 2016, the number of donations made in 2017, the age of the donor and the target. Which columns can be used as candidate predictors?

Donations 2016	Donations 2017	Age	Donation in 2017 (target)
5	2	68	1
3	0	65	0
2	0	23	0
8	6	56	1
