Answer:

You do an experiment.

Explanation:

Chemistry is still an experimental science. Notions of Lewis acidity/Lewis basicity are all very well. These notions are generalizations that account for observed chemical behaviour. So does the given species accept an electron pair? I don't know. Because I haven't done the experiment.
