Task: Question Generation
Input (English): Englishman Sir Francis Drake probably located the island on the final leg of his circumnavigation of the world (1577–1580). Further visits by other English explorers followed, and, once Saint Helena’s location was more widely known, English ships of war began to lie in wait in the area to attack Portuguese India carracks on their way home. In developing their Far East trade, the Dutch also began to frequent the island. The Portuguese and Spanish soon gave up regularly calling at the island, partly because they used ports along the West African coast, but also because of attacks on their shipping, the desecration of their chapel and religious icons, destruction of their livestock and destruction of plantations by Dutch and English sailors.
Output (English): Who gave up calling at the island due to attacks on their shipping?
