The passage given below is followed by four alternate summaries. Choose the option that best captures the essence of the passage. Scientific research shows that many animals are very intelligent and have sensory and motor abilities that dwarf ours. Dogs are able to detect diseases such as cancer and diabetes and warn humans of impending heart attacks and strokes. Elephants, whales, hippopotamuses, giraffes, and alligators use low-frequency sounds to communicate over long distances, often miles. Many animals also display wide-ranging emotions, including joy, happiness, empathy, compassion, grief, and even resentment and embarrassment. It’s not surprising that animals share many emotions with us because we also share brain structures, located in the limbic system, that are the seat of our emotions.
The similarity in brain structure explains why animals show emotions typically associated with humans.
The passage lists the remarkable sensory and motor abilities of animals and their wide range of emotions, and then explains that it is not surprising that animals share many emotions with us because we share brain structures in the limbic system.
The second summary picks only the detail about sensing and disease detection. The third invents a causal link between sensory abilities and emotions. The fourth states the emotions but leaves out the explanation.
The first summary gives the main claim with its reason: similar brain structure explains the shared emotions.
Hence, The similarity in brain structure explains why animals show emotions typically associated with humans.
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.
