Read the following article and select the best answer. Article: For hundreds of millions of years, turtles have struggled out of the sea to lay their eggs on sandy beaches, long before there were nature documentaries to celebrate them, or GPS satellites and marine biologists to track them, or volunteers to hand-carry the hatchlings down to the water's edge lest (for fear that) they become disoriented by headlights and crawl towards a motel parking lot instead. A formidable wall of bureaucracy has been erected to protect their prime nesting on the Atlantic coastlines. With all that attention paid to them, you'd think these creatures would at least have the gratitude not to go extinct (die out). But Nature is indifferent to human notions of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species of North Atlantic turtles, notably loggerheads, which can grow to as much as 400 pounds. The South Florida nesting population, the largest, has declined by 50% in the last decade, according to Elizabeth Griffin, a marine biologist with the environmental group Oceana. The figures prompted Oceana to petition the government to upgrade the level of protection for the North Atlantic loggerheads from "threatened" to "endangered"-- meaning they are in danger of disappearing without additional help. Which raises the obvious question: what else do these turtles want from us, anyway? It turns out, according to Griffin, that while we have done a good job of protecting the turtles for the weeks they spend on land (as egg-laying females, as eggs and as hatchlings), we have neglected the years spend in the ocean. "The threat is from commercial fishing," says Griffin. Trawlers (which drag large nets through the water and along the ocean floor) and longline fishers (which can deploy thousands of hooks on lines that can stretch for miles) take a heavy toll on turtles. Of course, like every other environmental issue today, this is playing out against the background of global warming and human interference with natural ecosystems. The... Question: What does the author mean by "Nature is indifferent to human notions of fairness" (Line 1, Para. 2)? - Nature is quite fair regarding the survival of turtles. - Turtles are by nature indifferent to human activities. - The course of nature will not be changed by human interference. - The turtle population has decreased in spite of human protection.
The turtle population has decreased in spite of human protection.

After trouble with the car, the television, we spent the evening waiting for the next trouble. Shortly after dinner we both smelled smoke. My wife, who was often careless when cooking, ran to the kitchen but returned looking puzzled. I rushed up the stairs to see smoke coming from under our bedroom door. I went to the bathroom and tied a wet cloth over my face. Then I returned to the bedroom, opened the door andcrawled in--there would be less smoke at floor level. With one hand reaching out in front of me I advanced carefully feeling for the switch to turn off the electric blanket. At that moment I heard the bell of a coming fire engine. Thank goodness my wife had not been wasting her time. Question: When the husband was upstairs trying to stop the smoke _ . - the wife telephoned the firemen - the firemen saw the smoke and came - thewife was downstairs doing nothing - they were in great danger
the wife telephoned the firemen

Read the following article and select the best answer. Article: Does happiness have a scent? When someone is happy,can you smell it? You can usually tell when someone is happy based on seeing them smile,hearing them laugh or perhaps from receiving a big hug.But can you also smell their happiness? Surprising new research suggests that happiness does indeed have a scent,and that the experience of happiness can be transmitted through smell,reports Phys.org. For the study,12 young men were shown videos meant to bring about a variety of emotions while researchers gathered sweat samples from them.All of the men were healthy and none of them were drug users or smokers,and all were asked to abstain from drinking or eating smelly foods during the study period. Those sweat samples were then given to 36 equally healthy young women to smell,while researchers monitored their reactions.Only women were selected to smell the samples,apparently because previous research has shown that women have a better sense of smell than men and are also more sensitive to emotional signaling--though it's unclear why only men were chosen to produce the scents. Researchers found that the behavior of the women after smelling the scents--particularly their facial expressions--indicated a relationship between the emotional states of the men who produced the sweat and the women who sniffed them. "Human sweat produced when a person is happy brings about a state similar to happiness in somebody who breathes this smell," said study co-author Gun Semin,a professor at Koc University in Turkey. This is a fascinating finding because it not only means that happiness does have a scent,but that the scent is capable of transmitting the emotion to others.The study also found that other emotions,such as fear,seem to carry a scent too.This ensures previous research suggesting that some negative emotions have a smell,but it is the first time this has proved to be true of positive feelings. Researchers have yet to isolate exactly what the chemical compound for the happiness smell is,but you might imagine what the potential... Question: What is the main finding of the new research? - Men produce more sweats. - Negative emotions have a smell. - Pleasant feelings can be smelt out. - Women have a better sense of smell.
Pleasant feelings can be smelt out.
