Final answer:
The text narrates the hardship of at least four individuals in a dingey at sea, and there's no mention of a giant throwing boulders. The answer to the question is false.
Step-by-step explanation:
The passage provided does not give clear evidence to support the claim that "Only three, including the narrator, made it out alive. The rest drowned at sea after the Giant hurled massive boulders at their raft." Instead, the text talks about the struggles of a small crew in a dingey facing the peril of the sea and their efforts to reach the shore. The text mentions a "correspondent," an "oiler," a "cook," and a "captain," which indicates that there were at least four individuals trying to survive the rough sea conditions. Moreover, there is no mention of a Giant throwing boulders. Thus, based on the excerpts from the text provided, the correct answer to the question would be false.
