Explanation:

Question 1

To determine the meaning of "emerge", we analyze the prefix "e - " (which often means "out" or "from") and the context (a humpback coming from the ocean). "Come out of" matches this meaning. "Go across" is incorrect (implies moving through), "act playfully" is unrelated, and "move very quickly" doesn't fit the context of a whale surfacing.

The options are about the author's purpose. The text (with references to whales and storytelling - like "entertaining story about whales") suggests the author aims to tell an engaging story about whales. "Tell results of a discovery" is too narrow, "persuade to use wind power" is off - topic, and "describe a scientist's life" doesn't match the whale - focused context.

The details in the Boston shop paragraph are likely about the start of research on whale flippers. "Help understand scientists' work" is too general, "show scientist - artist difference" is not supported, and "support whales are amazing" is not the main point of that detail. The detail is about the origin of the research.

Answer:

B. come out of
