Question: Read the following article and select the best answer. Article: Turns out we aren't good at walking and talking at the same time, according to a study of pedestrians on their cell phones. Nearly one-third of pedestrians (29.8% ) were distracted by their mobile devices while crossing the street, say researchers of a study published online in the journal Injury Prevention. Just as drivers who text, talk on cell phones, or adjust MP3 players increase their risk of losing control of their vehicles, pedestrians distracted by their conversations or their devices also put themselves at higher risk of getting into an accident. During the summer of 2012, scientists in Seattle, Wash. , studied 1,102 pedestrians at 20 crossroads seeing the city * s highest number of pedestrian injuries over the past few years. They watched how pedestrians crossed the street @ whether they looked both ways or obeyed the crossroad signal @ and also recorded how long it took pedestrians to do so.Distractions included listening to music with headphones, using a cell phone or earpiece to talk on a cell phone, text messaging, and talking with another person. Overall, researchers found the most common distraction among pedestrians was listening to music (11.2%), followed by text messaging (7.3%), and using a handheld phone(6.2%). But the most absorbing distraction was texting. Compared to pedestrians who were not distracted, those who were texting took 1.87 seconds longer to cross and were four times more likely to not look where they were going, disobey traffic lights, or cross outside of the crosswalk. While the study did not track injuries related to these trends, previous studies have linked such activities to a higher risk of being injured while crossing the street. Combined with the rise in the use of mobile devices, especially smart phones, the results raise concerns that multi-tasking while walking may be a rising concern for pedestrians. And that danger may only climb, as the number of wireless devices has already _ the population of the United States. Last year, roughly 1,152 people wound up... Question: The scientists did their study at the 20 crossroads in order to _ . - attract more attention - see more injuries - record more samples - find more pedestrians
Answer: record more samples

Question: Read the following article and select the best answer. Article: Are animal brains too simple for thoughts and choices? Stories about animal kindness have really changed my point of view. In fact, some stories are amazing, especially when animals are meeting with people. Here are two stories that interest me. James, a wildlife writer, told a story that an African woman had placed her baby in the shade of a tree while she was working. An elephant group walked by and saw the baby. Several elephants pulled leafy branches from the tree covered the sleeping baby. Flies can be a problem in Africa and the branches protected the baby from the flies. The elephants were so gentle and quiet that they did not even wake up the baby. Then the elephants walked away. An English magazine offers another story. Bill, a cat, stayed at home while its master was away on a trip, but the man was injured in a railway accident and died a few days later in a hospital. At the funeral, the Man's brother was surprised to see that Bill was there. The faithful cat had traveled a long way to the hospital, looked at the coffin , and then sadly returned home. Humans are only one part of the earth. The beautiful flowers are our sisters; the deer, the horses and the great eagles, these are our brothers. The sky and mountains, the cows and men, all belong to the same family. These stories, I hope, will inspire more people to treat animals as our friends rather than pets or our next meal.
