Counting carnivores is a tricky business. Individual identification is a tremendous challenge and requires highresolution cameras or good, unobstructed views in person. They are often shy and cover large distances. Lions are difficult to count even though they are social and sleep most of the day. Only a very few lion populations are known at the individual level, such as Liuwa Plains National Park, Zambia. Individual recognition of every lion in an area requires intense study, significant resources, and low numbers of individuals. Therefore, researchers use a variety of other imperfect techniques to estimate lion population size in all other lion areas. Some more common estimation techniques include spoor tracking or call-up surveys.
The drastic reduction in lion numbers and habitat highlighted by our research is certainly alarming from a conservation standpoint. Yet, African lions are not in immediate danger of extinction. Substantial lion populations exist in large, well-protected areas such as the Serengeti or Kruger ecosystem. Many of the remaining lion populations in East or Southern Africa are in well-protected areas such as national parks and game reserves (although some of these allow hunting). Nevertheless, this should not be used as a blanket statement; there are populations and even countries in these regions that have few or no lions remaining. Overall, lions in West and Central Africa are in the gravest danger of extinction. More than half of the populations vital to lion conservation in these regions (as noted by the IUCN) have been extirpated in the past five years, with several countries losing their lions entirely. According to our research, fewer than 500 lions remain in West Africa, scattered across eight isolated sites. This is of serious concern as these populations contain the most genetically unique lions in all of Africa and are most closely related to the Asiatic lion.
You cannot protect what you do not know you have. This is a simple but true adage. Our compilation needed to occur in order to prioritize areas for conservation action. With a good map, numbers, and some understanding of connectivity between the lion areas, we now know which populations are threatened with extinction or conversely, which are well connected and well protected.

Choose the correct sentence with the same meaning.
When is it time to stop studying?
It's 10 p.m. and six government employees are out checking the streets of Seoul, South Korea. But these are not police officers searching for teenagers who are behaving badly. Their mission is to find children who are still studying. And stop them. Education in South Korea is very competitive. The aim of almost every schoolchild is to get into one of the country’s top universities. Only the students with the best grades get a place. The school day starts at 8 a.m. and the students finish studying somewhere between 10 p.m. and 1 a.m. at night. This is because many go to private academies called hagwon after school. Around 74 percent of all students attend a hagwon after their regular classes finish. A year’s course costs, on average, $2,600 per student. In Seoul, there are more private tutors than schoolteachers, and the most popular ones make millions of dollars a year from online and in-person classes. Most parents rely on private tutoring to get their children into a university. With so much time spent in the classroom, all that students in South Korean high schools do is study and sleep. Some of them are so exhausted that they cannot stay awake the next day at school. It is a common sight to see a teacher explaining the lesson while a third of the students are asleep on their desks. The teachers don’t seem to mind. There are even special pillows for sale that fit over the arms of the chairs to make sleeping in class more comfortable. Ironically, the students spend class time sleeping so that they can stay up late studying that night. The South Korean government has been aware of the faults in the system for some time, but now they have passed some reforms. Today, schoolteachers have to meet certain standards or take additional training courses. However, the biggest challenge for the government is the hagwons. Hagwons have been banned from having classes after 10 p.m., which is why there are street patrols searching for children who are studying after that time. If they find any in class, the owner of the hagwon is punished and the students are sent home. It's a strange world, where some children have to be told to stop studying while others are reluctant to start. Adapted from: LATHAM-KOENIG, Christina & OXENDEN, Clive. American English File 3 - Workbook. 2"“ edition. Oxford: OUP, 2014.
In the sentence “However, the biggest challenge for the government is the hagwons.” (last paragraph), the word HOWEVER could be correctly replaced in this context, without change of meaning, by:
Cow Threat
Cows are walking machines. They transform materials (grass, hay, water, and feed) into finished products (milk, beef, leather, and so on).
As any factory, cows produce waste. Solid waste is eliminated through the rear end of these ‘complex machines’, and it is used as fertilizer.
The fermentation process in their four stomachs produces gas. These walking machines have two chimneys: one in the front end, and other in the rear end. Gaseous emissions through the front end chimney are called burps. Cows burp a lot. Every minute and half these burps release methane gas. Methane is dangerous to the planet because it contributes to the greenhouse effect.
The world population is growing very fast. That means there are more people eating beef. Consequently, there is more cattle – more walking machines – producing more methane gas.
This is the problem, but very few people want to change their eating habits. What about you?
Analyze these sentences:
1. The words people and cattle are being used in the text as nouns in the singular form.
2. In “…and it is used as fertilizer.”, the underlined word is an example of the comparative of equality.
3. The word in bold in “Consequently, there is more cattle” can be replaced by therefore without changing its meaning.
Choose the alternative which presents the correct ones.

UNEARTHED: REMAINS OF THE EARLIEST KNOWN TSUNAMI VICTIM
By Charles Choi | October 25, 2017 1:00 pm
Paragraph 1 Tsunamis have claimed hundreds of thousands of lives in the past two decades. Now a new study finds that a 6,000-year-old skull may come from the earliest known victim of these killer waves.
Paragraph 2 The partial human skull was discovered in 1929 buried in a mangrove swamp outside the small town of Aitape Papua New Guinea, about 500 miles north of Australia. Scientists originally thought it belonged to an ancient extinct human species, Homo erectus. However, subsequent research dated it to about 5,000 or 6,000 years in age, suggesting that it instead belonged to a modern human.
A Rare Specimen
Paragraph 3 The skull is one of just two examples of ancient human remains found in Papua New Guinea after more than a century of work there. As such, archaeologists wanted to learn more about this skull to elucidate how people settled this region.
Paragraph 4 The scientists went back to where this skull was found and sampled the soil in which it was discovered. They focused on details such as sediment grain size and composition.
Paragraph 5 In the sediment, the researchers discovered a range of microscopic organisms from the ocean known as diatoms. These were similar to ones found in the soil after a 1998 tsunami killed more than 2,000 people in Papua New Guinea — for instance, their shells of silica were broken, likely by extremely powerful forces.
Paragraph 6 These diatom shells, combined with the chemical compositions and the size ranges of the grains, all suggest that a tsunami occurred when the skull was buried. The researchers suggested the catastrophe either directly killed the person or ripped open their grave.
Paragraph 7 Tsunamis, which are giant waves caused by earthquakes, volcanic eruptions or underwater landslides, are some of the deadliest natural disasters known. The 2004 tsunami in the Indian Ocean killed more than 230,000 people, a higher death toll than any fire or hurricane.
Paragraph 8 The site where the skull was found is currently about 7.5 miles away from the coast. Still, the researchers noted that back when whoever the skull belonged to was alive, sea levels were higher, and the area would have been just behind the shoreline.
Paragraph 9 The waves of the tsunami that hit Papua New Guinea in 1998 reached more than 50 feet high and penetrated up to three miles inland. “If the event we have identified resulted from a similar process, it could have also resulted in extremely high waves,” study co-lead author Mark Golitko, an archaeologist at the University of Notre Dame in Indiana and the Field Museum in Chicago.
Paragraph 10 These results show “that coastal populations have been vulnerable to such events for thousands of years,” Golitko said. “People have managed to live with such unpredictable and destructive occurrences, but it highlights how vulnerable people living near the sea can be. Given the far larger populations that live along coastlines today, the potential impacts are far more severe now.”
Paragraph 11 Golitko plans to return to the area over the next few years “to further study the frequency of such events, how the environment changed over time, and how people have coped with the environmental challenges of living in that environment.” He and his colleagues detailed their findings Wednesday in the journal PLOS O.
