PROBLEM: Greenwich is on the River, five miles from the middle of London, and its history is two thousand years old. The first English people were fishermen there, and they named the place Greenwich, meaning "green village". Later the English kings and queens lived at Greenwich in their beautiful places. The name of the earliest palace was Placentia. Henry VIII lived there. He knew that England must be strong at sea. So he started two big ship-yards at Greenwich. But trouble was coming to Greenwich. In 1649, a war started in England and for eleven years there was no king. The men who had worked for him at Placentia decided to live the place themselves. They sold all its beautiful things. Finally, the war ended and King Charles II came back. But Placentia was falling down. So King Charles built a new and bigger palace, which is now open to the public. At this time, Charles was worried about losing so many of its ships at sea: their sailors did not know how to tell exactly where they were. So in 1675, Charles made John Flamsteed, the first astronomer in England, try to find the answer. Flamsteed worked in a new building on the high ground in Greenwich Park. From it with a telescope which he made himself, Flamsteed could look all round the sky. And he did, night after night, for twenty years. Carrying on Flamsteed's work a hundred years later, an astronomer called Harrison finally made a clock which told the time at sea, and helped sailors to know where they were. You can see Harrison's clock, still working, in Greenwich's museum of the sea. Because of Flamsteed's work, every country in the world now tells its time by Greenwich Time.

SOLUTION: Who made the first clock which could tell the time at sea?

PROBLEM: Swimming in the water of Hawaii's Big Island is a fun experience. But it can be more exciting if there are dolphins swimming around and jumping out of the sea too. For many people, it would be a wonderful dream to swim with these lovely animals! However, this may not be good for dolphins. They may get hurt because of human interaction . Dolphins are active and usually look for food at night. In the day, they like to rest in shallow bays . Many people think the dolphins are awake during the day as they swim. But when they sleep they rest half of their brain and keep the other half awake to breathe, so they may be sleeping even when they're swimming in the water. From 2010 to 2013, spinner dolphins of Hawaii's Big Island were exposed to human activities more than 82 percent of the time, according to Julian Tyne, a researcher at Australia's Murdoch University. The National Oceanic and Atmospheric Administration (NOAA) says disturbing the animals in their near-shore habitat could force them to swim to less favorable places, putting them at risk of attack by sharks and other animals. Besides, when people are around, dolphins become more active. Thus, they can't get enough sleep. "Disturbing their resting behaviors can actually affect their long term health and the health of the dolphin population," Ann Garrett of NOAA's National Marine Fisheries Service told the Associated Press. As a result, the NOAA wants to make rules to help protect the dolphins. For example, the agency may ban swimming with the Hawaii spinner dolphins. Or they may stop people from swimming in shallow bays when the dolphins are resting. Tour operators must also be taught to watch for signs to know when the dolphins are in their resting state.

SOLUTION:
Which activity is against the rules?
