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.

Question: Read the following article and select the best answer. Article: Do's and Don'ts in Whale Watching The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait,where killer whales are found on a daily basis each summer. It is strongly recommended that vessel operators follow these guidelines for all kinds of whales. * Approach whales from the side, not from the front or the back. * Approach no closer than 100 metres, then stop the boat but keep the engine on. * Keep noise levels down-no horns, whistles or racing of engines. * Start your boat only after the whales are more than 100 metres from your vessel. * Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales. * Approach and leave slowly, avoiding sudden changes in speed or direction. * Avoid disturbing groups of resting whales. * Keep at low speeds and remain in the same direction if travelling side by side with whales. * When whales are travelling close to shore, avoid crowding them near the shore or coming between the whales and the shore. * Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales. * If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales. * Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines.
