{Which of them it was} (	o tis ara ei(8820)ex aut(936e)). Note
the article 	o with the indirect question as in verses  2,4 .
The optative ei(885c) here is changed from the present active
indicative estin, though it was not always done, for see
dokei in verse  24  where the present indicative is retained.
They all had their hands on the table. Whose hand was it?
