Take the following as truth: Greater evidence of such a people is found on Mallorca and Menorca than on Ibiza, but one of the Balearics' most important sites is actually on the island of Formentera, where the megalithic monument/tomb of Ca Na Costa has been dated to 2000 b.c.
Then the following statement: "Formentera is a very important site." is true, false, or inconclusive?
