Read the following article and select the best answer. Article: Squirrels often communicate with whistles, chirps and chucks, which sound like the word "chuck". Whistles and chirps are like the sounds that many birds make.Now scientists have translated some of their squirrel-speak. Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls.The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture their reponses.Some squirrels lifted their heads up and became.Alert .Creatures that were more frightened simply ran for their lives and dived into caves. "In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger.' " Hare told.Discovery News. Hare and some other researchers believe such sounds arc part of an advanced language that develops just as all other communication systems. Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behaviour, thus increasingly the caller's social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls. In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too.According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms. While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests . Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide "hope that humans will gain a greater appreciation and... Question: If a squirrel is in a very dangerous situation, it would probably make _ . - whistles with chucks - pure chirps - whistles without chucks - repeated chucks
pure chirps

(Question)
Read the following article and select the best answer. Article: Roger Alvarez, 22, was one of the 52 percent of students who didn't make it through his senior year at Manual Arts High School in Los Angeles. He dropped out several years ago, but by the time he was in ninth grade, Alvarez says he already knew he wasn't going to graduate. "There's a certain amount of knowledge you have to have when you enter in a specific grade, and I didn't have it." Alvarez says,"Every class I used to go in, I was like, 'Do I know this? I don't know this.'" It was a shameful attitude, he tells his former English teacher, Antero Garcia, 29. "You were determined to help me, but what was I willing to give? I could have actually tried." For his part, Garcia wants to know how he could have reached out to Alvarez better, but Alvarez says Garcia had always been helpful. "I mean, you could cheer me up, and then I see other students doing way better," Alvarez says,"So then, I get nervous. I get stuck, and then _ ." He felt the situation was hopeless. "You talked to me like if I could do it, but inside me, I knew I couldn't." he tells Garcia,"I just didn't want you to think that I'm...stupid." Now, school is a life tool that Alvarez says he's missing--but his teacher isn't to blame. "Always, I just wanted you to know...you were a good teacher, and I always respected you." he tells Garcia,"Some teachers, I felt like they only wanted to teach a certain group of people. But you looked at me and you paid attention." "Maybe it didn't get me to graduate, but there're a lot of teachers, they don't take the time to take a look. And it was never your fault." Alvarez now works the night shift at a loading dock . He still hopes to get his degree one day. Question: By saying "my motivation goes to the floor", Alvarez meant _ . - he hid his goal from others - he lost heart gradually - he built up his motivation - he fell to the ground completely
(Answer)
