Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf's howl and it appears that there may be more to discover. One theory is that wolves howl to bend better together. It's almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior. Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be "punished" for Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ----Why do welves howl for sure? What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of "roll rall"where wolves all howl togeter to howl, very likely others will follow.

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: 400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate change. Moss found buried beneath the Teardrop glacier on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists. Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems . Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts. Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before. While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte plant that mainly grows across Canada, the US and the Highlands of Scotland. Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, "When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that _ When we think of thick areas of ice covering the landscape, we've always thought that plants... Question: Dr La Farge's research is of great importance to _ . Options: A: knowing what the plants during the Little Ice Age were like B: understanding how ecosystems recover from glaciers. C: regrowing many species that have been destroyed before. D: figuring out the effects of melting ice caps on moss.
Ans: B

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: Malala Yousafzai, the teen activist from Pakistan, has just become the youngest person ever to win a Nobel Prize. In 2012, Malala survived from being shot by terrorists for speaking out for a girl's right to be educated in her native country. She is being recognized today for her global activism on education for girls. Winning this award is a huge honor, especially for such a young person. Malala's journey to the Nobel Prize has not been easy. She grew up in a dangerous district of Pakistan called the Swat Valley. This area was taken over by the Taliban. The Taliban ruled the district with an iron fist. They were especially cruel to women, not allowing them to go shopping, have jobs, or go to school. In 2009, Malala began speaking out publicly for every girl's right to an education. She blogged about how the Taliban didn't want her to go to school. She also continued to attend her local school, despite the danger involved. Then, in 2012, the Taliban tried to kill Malala to silence her. Two Taliban gunmen shot her and two other students while they were on a school bus. Malala was flown to the United Kingdom for immediate medical treatment. Malala eventually recovered from her injuries. She now lives in Birmingham, England, and continues to work hard to support girls' and women's rights around the world. "The terrorists thought that they would change my aims and stop my ambitions," she said, "but nothing changed in my life except this. Weakness, fear, and hopelessness died. Strength, power, and courage were born." The 17-year-old girl from Pakistan is sharing the 2014 Nobel Peace Prize with a children's activist Kailash Satyarthi, who is from India Satyarthi leads many campaigns dedicated to removing child labor. Question: After recovering from being shot, Malala _ . Options: A: felt depressed B: was devoted to removing child labor C: decided to stop her ambitions D: continued to fight for women's right
Ans:
D
