We have already seen how the pronouns é, í, íad are repeated in identification copula sentences (see exercise 10.1). For example:
* Is é an dochtúir é
* Is iad na buaiteoirí iad.

But if we specify the subject more closely, the pronoun at the end of the clause is omitted:
* Is é Seán an dochtúir.
* Is iad sin na buaiteoirí.

In this exercise, connect the two pieces of information supplied using is.
