input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: 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... Options: A Monkeys Are Clever Than Crows B Crows Show Cleverness C Crows Did Well in RMTS D Crows May Understand Analogies. Answer: B Crows Show Cleverness Question:

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Now let's look ourselves as a species in relation to ecosystem balance.Modern scientists believe that humankind, like other animals, evolved through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape) group. Despite this similarity with other creatures, however, the evolution of humankind differs from that of other species in one important and unique way. In other species, evolution has led to specialization, both in the species abilities and in its place within the environmental structure. For example, the giraffe is much adapted to feeding on treetops, but it is also specialized and thus limited to feeding on trees and shrubs. Only with great difficulty can it bend down to graze on the ground. Similarly, the anteater is extremely well adapted to eating ants but is unable to catch or eat other animals. The same is true for countless other species. For humankind it is opposite. Our evolution had led to a very generalized ability. Our highly developed intelligence and ability to make and handle tools mean that we can do almost anything. Humans evolved in such a way that we are able to move into every environment on Earth and even into space. No natural competitor offers great resistance, and other natural enemies such as disease have been controlled. Said another way, we see in humankind a great imbalance between biological potential and environmental resistance. The result is the rapidly increasing world population, frequently referred to as the population explosion. Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities. Options: A increase the population B resist natural offers C go to the moon D cure all diseases Answer: C go to the moon Question:
