[EX Q]: Question: How many years before the The Portuguese found Cape Palmas was it first discovered? Passage:Down the coast of Africa: The Portuguese reached the westernmost point of Africa in 1444 and in 1458 rounded Cape Palmas where the coast tends eastward. Here the trade winds gave out and they faced the irregular winds near the doldrums and the east-flowing Guinea Current. In 1471 they reached the Gold coast where they found the gold that had previously come by caravan across the Sahara. In 1474 Lopes Gonçalves reached the point where the coast turns south and became the first European sailor to cross the equator. In 1475-79 Spain and Portugal fought along the coast. The Treaty of Alcáçovas gave the whole area to the Portuguese except for the Canaries. This was the first colonial war and the first colonial treaty. In 1482 Diogo Cão continued south against the Benguela current and the southeast trade winds, reaching the Congo River in 1482 and Cape Cross in Namibia in 1485. In 1487 Bartolomeu Dias reached Cape Voltas near the mouth of the Orange River and stood out to sea. Although the sources are not clear, he may have guessed that there were southern westerlies and was trying a volta do mar. After many days, at about 40 degrees south he discovered the westerlies and turned east. Finding no land after a number of days he turned north and reached Mossel Bay about 400 km east of Cape Town. He continued east against the Agulhas current to Algoa Bay where the coast began to turn north. Guessing that he had found the route to India, he turned back, discovered and rounded the Cape of Good Hope and reached Lisbon in 1488. In 1493 Columbus arrived at Lisbon with news of the new world and reported that he had sailed out of sight of land for five weeks.
