Read the article and select the best answer. Article: People with bigger brains ftend to score higher on standardized tests of intelligence, according to new study findings. However, the study author Dr Michael A.McDaniel of the Virginia Commonwealth University in Richmond emphasized that these findings represent a general trend, and people with small heads should not automatically believe they are less intelligent. For instance, Albert Einstein's brain was "not particularly large", McDaniel noted. "There's some relationship between brain size and intelligence on the average, but there's plenty of room for exceptions," he said. Interest in the relationship between brain size and intelligence grew in the1830s, when German anatomist Frederich Tiedmann wrote that he believed there was "an unquestionable connection between the size of the brain and the mental energy displayed by the individual man". Since that statement, scientists have conducted numerous studies to determine if Tiedmann's assertion was, in fact, correct. Most studies have looked into the link between head size and intelligence. More recently, however, researchers have published additional studies on brain size and intelligence, measured using MRI scan . For his study, McDaniel analyzed more than 20 studies that looked into the relationship between brain size and intelligence in a total of 1,530 people. The studies showed that on the average, people with larger brain volume tended to be more intelligent. The relationship between brain volume and intelligence was stronger in women than men, and in adults than in children. McDaniel notes in the journal Intelligence. McDaniel is not sure why the relationship was stronger for adults and women. "Other research has shown that women, on the average, tend to have smaller brains than men, but score just as well--if not higher--in tests of intelligence," he said. McDaniel insisted that the relationship between brain size and intelligence is not a "perfect" one. "One can certainly find lots of examples of smaller-sized people who are highly intelligent," he...

Options: A: proves Tiedmann's idea was completely true B: shows women are smarter than men C: involves many studies and a lot of people D: explains why people with smaller brains are clever

It was the first serious one in 40 years of farming side by side, sharing machinery, and trading labor and goods as needed. Then the long cooperation fell apart. It began with a small misunderstanding and it grew into a major difference, and finally it exploded into an exchange of bitter words followed by weeks of silence. One morning there was a knock on John' door. He opened it to find a man with a carpenter's toolbox. "I'm looking for a few days' work," he said. "Could I help you?" "Yes," said the older brother. "I do have a job for you. Look across the creek at that farm. That's my neighbor, in fact, it's my younger brother. Last week there was a meadow between us and he took his bulldozer to the levee and now there is a creek between us. Well, he may have done this to spite me, but I'll go him one better. I want you to build me a fence--an 8-foot fence --so I won't need to see his place anymore. Cool him down, anyhow." The carpenter said, "I think I understand the situation. I'll be able to do a job that pleases you." The older brother had to go to town for supplies, so he helped the carpenter get the materials ready and then he was off for the day. The carpenter worked hard all that day measuring, sawing, nailing. About sunset when the farmer returned, the carpenter had just finished his job. The farmer's eyes opened wide, his jaw dropped. There was no fence there at all. It was a bridge-- a bridge stretching from one side of the creek to the other! A fine piece of work-- and his younger brother was coming across, his hand outstretched. "You are quite a fellow to build this bridge after all I've said and done." The brothers stood at each end of the bridge, and then they met in the middle, taking each other's hand. They turned to see the carpenter lift his toolbox on his shoulder. "No, wait! Stay a few days. I've a lot of other projects for you," said the older brother. "I'd love to... Question: What was life like for the two brothers before the conflict? Options: A: They lived a poor, miserable life. B: They were friendly neighbors, helping each other. C: They never spoke to each other. D: They lived together as one family.

Article: Your next Saturday night takeaway could be brought to you by a robot after a major food delivery company announced plans to use automated vehicles to transport meals. Europe's biggest online takeaway food company Just Eat has partnered with Starship Technologies to deliver food with robots on the streets of London later this month. "Nobody has ever done deliveries with land-based robots," said Allan Martinson, the chief operating officer of Starship. The robot courier can travel up to 4 miles per hour for about 10 miles. It uses a GPS signal and nine cameras to navigate . Instead of a person arriving at their door, customers could find themselves receiving a notification on their phone that says a robot is on its way and a code to unlock the automated courier. "Put the code in, the robot opens up, and there's your food," said David Buttress, chief manager of Just Eat. The robot, which has so far been tested in Greenwich, Milton Keynes and Glastonbury, costs PS1 to transport within 3 miles, compared with the PS3 to PS6 it costs for a human courier. To date 30 robots have driven nearly 5,000 miles without getting into an accident or finding themselves picked on by passers-by. They have driven in more than 40 cities around the world, including London and Tallinn, Estonia. An initial worry was how the public would react to robots. But Martinson said the public has been calm when passing the delivery machine on the streets. "The most surprising reaction has been the lack of reaction," said Martinson. Another significant fear was that people would disrupt the robots, or try to steal them and their contents. To prevent this, the robot is fitted with nine cameras, two way audio, and movement sensors that send a warning if it is lifted off the ground. And it opens only with a pass code provided to the customer via a notification. "It's much easier to shoplift than it is to steal a robot," said Martinson. Question: Which of the following is one of the worries about Starship robots? Options: A: People's indifference to the robots. B: Safety of the robot delivery. C: Accuracy of the robot delivery. D: People's concern about public traffic.
