I'm taking a test and have to guess the right answer to the question after the article. Article: 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 . It was once thought that only humans could understand analogies,which help us to solve problems creatively,put things into categories,and make scientific discoveries. To test this ability in animals,scientists do"relational matching-to-sample"(RMTS) tests,according to the IFL Science website.If a pair was AA,for example,then picking BB to match it would be correct.If the pair was CD,however,then EF would be correct. Apes and monkeys have learned RMTS,but scientists wanted to know if crows could do it,too.An international team led by Edward Wasserman from the University of Iowa in the US first trained two hooded 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 (in the color1,shape,or number of shapes pictured),while the other wasn't.The cup with the card that matched the sample card contained two wormsto 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,Science News reports. Wasserman was surprised that crows were able to solve the problem without any training in RMTS."What the crows have done is extraordinary,"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... Question: Which of the following is TRUE about the tests on the hooded crows? Options: 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.

I'm taking a test and have to guess the right answer to the question after the article. Article: Life in 2060 Let us suppose it is now about A.D. 2060. Let's make believe(;) it is about sixty years from now. Of course, things have changed and life is very different. Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment of young and old. What are people eating now? People are still eating food. They haven't yet started to take on heir supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants. Since there are several times as many people in the world today as there were a hundred years ago, most of our planet's surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good. Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then. People are now largely vegetarians . You see, as the number of people increases, the number of animals decreases. Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more. Such would be our life in 2060. Question: Why are people largely vegetarians in 2060? Options: A: Because they don't eat meat . B: Because doctors advise them not to eat meat. C: Because the number of animals decreases. D: Because all the animals have died of diseases.

I'm taking a test and have to guess the right answer to the question after the article. Article: On a summer day, John was sitting on a beach in Hawaii with his parents. The six-year-old child suddenly said he was so lucky because he had so many toys to play with at home. His surprised parents replied that he was lucky, since a lot of kids didn't have any toys at all. "How can that be?" John said, confused, but then he said that he would like to get toys for those children. His parents naturally thought their son was just kidding. But as soon as they returned home, John began using his pocket money to buy toys for other kids and asking his friends to do the same. His parents responded by organizing pizza suppers for other families interested in helping other children that can't afford to buy toys. John thought that he just wanted to cheer those kids up. John's parents started to find a place that would allow children as young as six and seven to volunteer. They finally find a day care center for disabled children to let John and his friends visit. They went and played with these kids, playing around the room as if they belonged there. John and his friends named their work Kids Cheering Kids. John and his friends visited kids at some childcare centers, helping out with a party they organized. They also prepared a performance for children with disabilities. Their activities have drawn public concern. The spirit of helping is as fresh as it was that day in Hawaii. "The whole purpose," John says, "is to make the kids feel better." Question: What was John's parents' attitude towards his plan? Options: A: Positive. B: Critical. C: Doubtful. D: Puzzled.
