Article: Ladybirds didn't have black spots on their backs at first. Then a storm broke out, and their famous guide, Caius Insectus, disappeared into the flood , and the few ladybirds who survived had to choose a new leader to guide them out of trouble. They decided that their new leader would be the first ladybird to successfully travel south to the Great Lake and return to describe it. Many young ladybirds moved off immediately into this adventure. One by one they returned and told of how beautiful the southern lake was at that time of year, with its clear waters and flowers. However, the last of the ladybirds was late in getting back. He hadn't managed to reach the lake. Everyone criticized him, and they prepared to continue their journey the next day.

Article: It seems that there is no middle ground when it comes to cats. People either love them or hate them. These feelings are not new either. All through history, cats have been worshiped or hated. A study of ancient writings and evidence found in tombs indicates that for the past 5,000 years, cats have been kept as pets in China, Arabia, Egypt, and India. However, this isn't very long compared to dogs, which have been domesticated for 50,000 years. Still, while the period in which cats have been domesticated may be quite short, it has definitely had its high and low points. Cats were at their highest position of domesticated life in ancient Egypt. There were more cats living in Egypt during the time of the pharaohs than in any other place in the world since that time. This high number of cats was probably due to the laws protecting them. Cats were associated with the moon goddess, Bast, so the Egyptians worshiped them as holy animals. If anyone was caught killing a cat, the person could be put to death. Families in Egypt also mourned the death of a cat and had the body of the dead cat wrapped in cloth before it was finally laid to rest. This respect for cats carried over to the Roman Empire where cats were the only animals allowed into temples. This fact was probably due to the ability of cats to keep the temples free of mice and rats. With the coming of the Dark Ages in Europe, the place of cats in society took a turn for the Empire, Christians began to associate cats with pegan beliefs. Cats had a reputation as helpers of witches. When a person was accused of being a witch, a cat would often be put on trial with the person. The cat would be tortured to try and make the person tell the truth, and usually the cat and the person would end up being burned in a bonfire or drowned. Bonfires of collected cats were not uncommon during this time. The days of hunting witches have ended, but other myths about cats still hold out. For a while, people in some places used to bury live cats under new buildings for good luck. As well, many people today continue to believe that black cats bring bad luck. If a black cat walks in front of a person, that person must take extra care in the near future to watch out for dangerous situations. Regardless of superstition , cats remain a popular pet today. Some cat experts believe that a cat never truly be domesticated because it may turn wild and run away at any time. However, this claim has not put people off keeping cats in their homes. A third of homes in the United States have cats, and one out of every three of these homes keeps both a dog and a cat. Especially in large cities, many people in small apartments have found that cats make much better pets than dogs. Cats may not be worshiped as gods any more, but there are people who seem to think of their cat as their children. These cat owners will do almost anything to keep their pets healthy and happy. For those cat owners who have always wondered what their pets are trying to tell them, a Japanese company may have come up with the perfect invention. In 2003, the Takara Company announced the Meowlingual, a cat translation device. The Meowlingual uses a microphone, display, and cat voice analyzer to analyze a cat's meows to determine which of 200 phrases a cat is trying to say. According to a company spokesperson, "... cat owners all over the world have been telling Takara, ' We want a cat translator!'" Now, the company "is making their dream come true by bringing in a new era of communication between cat lovers and their pets."

Options: (A) the status of cats throughout history (B) the evolution of different species of cats (C) the popularity of the cats today (D) communication between cats and their owners

Article: A romantic message-in-a-bottle discovered by a mother and daughter at a Scottish beach has sparked a mystery about whether it could have travelled 5,000 miles across the seas from China. Nicola MacFarlane, 41, and daughter Lucy, four, from Portobello, near Edinburgh, were looking for driftwood on Portobello Beach when they came across an old glass bottle containing a note inside written in _ . Now the family are trying to work out if the letter has managed the extraordinary journey across the Philippine Sea, into the Indian Ocean and through both the South Atlantic and the North Atlantic Ocean's before washing up on the shores of Great Britain. It was written on Chinese Valentine's Day or Qixi Festival as it is more traditionally known, lunar July 7, 2012, so it sent off as recently as six days ago because it followed the modern calendar, which celebrated the occasion on August 23. Nicola was still excited to read about the Chinese love story after having it translated. "I really do hope that it is from China but even it is from nearer to home, it's still a lovely gesture and an inspiring find. It's a love story regardless of where it came from. Nicola, who runs a beach art business in Portobello, added: "I'm always at the beach looking for bits of driftwood but I've never come across anything like this before. We knew it was Chinese, but we had no idea what it said.' Unable to read the Mandarin text, Nicola turned to the internet and her Australian friend, Julie Gould, whose daughter attended a Chinese school in Sydney. Several hours later Julie returned with the news that it was in fact a love letter. The translated letter reads: "Da Hai(Ocean), I hope no-one will get this bottle, as we just wish you can hear our voice, and get your blessing. Today is the Chinese Valentine's Day, we pray that our relationship will last forever and we will have a long happy life together..." Nicola said: "It sounds to me like the couple are in love but cannot be together so they have sent the message to tell the world of their love."
Question: When did Nicola and her daughter come across the message-in-bottle?
Options: (A) On July 15, 2012. (B) On August 29, 2012. (C) On August 31, 2012. (D) On September 2, 2012.
