PEOPLE may use the expression "birdbrain" in English to talk about someone who is stupid, but crows prove that this is unfair. Now it has been discovered that crows may understand analogies  . To test this ability in animals, scientists do "relational matching-to-sample (RMTS)"tests. If a pair was AA, for example, then picking BB to match it would be correct. An international team led by Edward Wasserman in the US first trained two crows to match things by color1, shape, and number in what is called" identity matching-to-sample (IMTS)" , then moved onto RMTS. For the IMTS test, the birds were put in a cage with a plastic tray that had three cards and two cups in it. The card in the middle was the sample card. The cups on either side were covered with the other two cards. One was the same as the sample, while the other wasn' t. The cup with the card that matched the sample card contained two worms to eat. In the second part of the experiment, the birds were tested with relational matching pairs. A card with two same- sized circles, for example, meant they should pick the test card with two same-sized squares and not two different-sized circles. The birds did well in the more difficult test and picked the correct card more than three quarters of the time. Wasserman was surprised that crows were able to solve the problem without any training in RMTS. He said in a news release: "Honestly, if it was only by force that the crows showed this learning, then it would have been an impressive result. But this was spontaneous." So perhaps it' s time to stop saying " birdbrain" permanently. Which of the following is TURE about the tests on the crows? A) The birds did better in RMTS than in IMTS. B) The birds were first made to do RMTS, then IMTS. C) The birds picked almost all the correct cards in RMTS D) In the IMTS test, the birds needed to identify the sample card to get rewards.

Thousands of cities around the globe turned off their lights for an hour to mark Earth Hour 2014, a symbolic show of support for the environment organized by the World Wide Fund for Nature.  Since the movement began in Sydney, Australia, in 2007, it has spread to more than 7,000 cities across more than 160 countries. Singapore continues to hold one of the world's largest lights-off events, drawing around 9,000 people this year to Marina Bay Sands, a commercial center typically awash in electricity.  To mark the event actors Andrew Garfield, Jamie Foxx, Emma Stone and a group of other famous stars from The Amazing Spider-Man 2 movie were in town.  Other iconic landmarks that fell dark included the Petronas Twin Towers in Kuala Lumpur, Bangkok's Wat Arun temple, the Empire State Building in New York, the Eiffel Tower in Paris, Sydney Opera House, Red Square in Moscow, the Bird's Nest in Beijing and Hong Kong Harbor.       As the movement has grown, more organizations and business have committed to switching off their lights in support of efforts to reduce their environmental footprint. In Singapore, at least 600 organizations and companies agreed to either switch off their lights or participate in movements to use fewer plastic bags, take shorter showers, turn up their air-conditioning units or switch to LED lighting.  This year the World Wide Fund for Nature, which first launched worldwide Earth Hour, also launched Earth Hour Blue, a crowdfunding platform aimed at raising money for environmental projects around the globe. On Mar. 26 a project to stop the illegal wildlife trade in Asia by providing assistance to wildlife rangers became the first one to reach its target of $20,000 by relying completely on crowdfunding.  The hour-long event has little if any impact on electricity consumption, but as an awareness raising event it has registered success.  In a statement to mark Saturday's event, Andy Ridley, CEO and Co-Founder of Earth Hour, said Asia's rapidly growing digital presence is an added bonus that has... We can infer from the report that   _ A) Australia and Singapore were the first two countries to launch Earth Hour B) More than 7000 cities from 160 countries took part in Earth Hour 2014 C) Some famous movie stars from The Amazing Spider-Man 2 were invited to Singapore to celebrate the event D) The World Wide Fund for Nature first organized Earth Hour worldwide

The book also encourages children to face their fears."I think it's really good to show that Max is friends with the monsters," Davis said."Kids can find out monsters aren't always the thing under the bed that's going to scare them.I think this is good because it shows that the children can go to scary places but still have a positive experience." Since the book has been successful throughout the years,a movie was recently made and many people are excited to see it.Davis said she thinks the movie will be wonderful but it might be a little scary for younger children."You don't want bad dreams over a book that's extremely wonderful'" Davis said.
