Answer
Brief Explanations:
The passage starts by stating that carrots are good for general eye health but don't improve night vision. Then it explains that the myth of carrots improving night vision originated from British propaganda during World War II. The British government used radar (a new technology) to track German planes at night. To keep radar a secret, they told the media their pilots could see German planes because they ate many carrots. As a result, people believed eating carrots would help with night vision. The second option encompasses this entire narrative - starting from the propaganda (British media campaign aspect, as the government told the media) leading to people's belief about carrots and night vision. The first option only mentions the British government telling the media about pilots eating carrots, which is just a part of the story and doesn't explain the resulting belief (the main idea is about the origin of the myth that carrots improve night vision, not just the government's statement to the media).
Answer:
Because of a British media campaign, people thought that eating carrots would improve their night vision.
