The passage below is accompanied by four questions. Based on the passage, choose the best answer for each question. (. . .) There are three other common drivers for carnivore-human attacks, some of which are more preventable than others. Natural aggression-based conflicts – such as those involving females protecting their young or animals protecting a food source – can often be avoided as long as people stay away from those animals and their food. Carnivores that recognise humans as a means to get food, are a different story. As they become more reliant on human food they might find at campsites or in rubbish bins, they become less avoidant of humans. Losing that instinctive fear response puts them into more situations where they could get into an altercation with a human, which often results in that bear being put down by humans. “A fed bear is a dead bear,” says Servheen, referring to a common saying among biologists and conservationists. Predatory or predation-related attacks are quite rare, only accounting for 17% of attacks in North America since 1955. They occur when a carnivore views a human as prey and hunts it like it would any other animal it uses for food. (. . .) Then there are animal attacks provoked by people taking pictures with them or feeding them in natural settings such as national parks which often end with animals being euthanised out of precaution. “Eventually, that animal becomes habituated to people, and [then] bad things happen to the animal. And the folks who initially wanted to make that connection don’t necessarily realise that,” says Christine Wilkinson, a postdoctoral researcher at UC Berkeley, California, who’s been studying coyote-human conflicts. After conducting countless postmortems on all types of carnivore-human attacks spanning 75 years, Penteriani’s team believes 50% could have been avoided if humans reacted differently. A 2017 study co-authored by Penteriani found that engaging in risky behaviour around large carnivores increases the likelihood of an attack. Two of the most common risky behaviours are parents leaving their children to play outside unattended and walking an unleashed dog, according to the study. Wilkinson says 66% of coyote attacks involve a dog. “[People] end up in a situation where their dog is being chased, or their dog chases a coyote, or maybe they’re walking their dog near a den that’s marked, and the coyote wants to escort them away,” says Wilkinson. Experts believe climate change also plays a part in the escalation of human-carnivore conflicts, but the correlation still needs to be ironed out. “As finite resources become scarcer, carnivores and people are coming into more frequent contact, which means that more conflict could occur,” says Jen Miller, international programme specialist for the US Fish & Wildlife Service. For example, she says, there was an uptick in lion attacks in western India during a drought when lions and people were relying on the same water sources. (. . .) The likelihood of human-carnivore conflicts appears to be higher in areas of low-income countries dominated by vast rural landscapes and farmland, according to Penteriani’s research. “There are a lot of working landscapes in the Global South that are really heterogeneous, that are interspersed with carnivore habitats, forests and savannahs, which creates a lot more opportunity for these encounters, just statistically,” says Wilkinson.
According to the passage, which of the following scenarios would MOST likely exacerbate the frequency of carnivore-human conflicts?
Unleashing dogs by pet owners in areas with known high concentrations of large carnivores.
The passage lists risky human behaviour as a major cause of attacks; one of the two most common risky behaviours is walking an unleashed dog, and most coyote attacks involve a dog.
Letting dogs off the leash where large carnivores are concentrated would therefore raise the number of conflicts.
Managing food waste and addressing the effects of climate change would reduce conflicts, and photographing animals from secured viewing areas avoids the risky close contact the passage warns about.
Hence, Unleashing dogs by pet owners in areas with known high concentrations of large carnivores.
Zombie cells may contribute to age-related chronic inflammation: this finding could help scientists understand more about the aging process and why the immune system becomes less effective as we get older. Zombie or “senescent” cells are damaged cells that can no longer divide and grow like normal cells. Scientists think that these cells can contribute to chronic health problems when they accumulate in the body. In younger people, the immune system is more effective at clearing senescent cells from the body through a process called apoptosis, but as we age this process becomes less efficient. As a result, there is an accumulation of senescent cells in different organs in the body, either through increased production or reduced clearance by the immune system. The zombie cells continue to use energy though they do not divide, and often secrete chemicals that cause inflammation, which if persistent for longer periods of time can damage healthy cells leading to chronic diseases.
