Read the text to answer question. The aliens among us Humans think of themselves as the world’s apex predators. Hence the silence of sabre-tooth tigers, the absence of moas from New Zealand and the long list of endangered megafauna. But sars-cov-2 shows how people can also end up as prey. Viruses have caused a litany of modern pandemics, from Covid-19, to hiv/aids to the influenza outbreak in 1918-20, which killed many more people than the first world war. Before that, the colonisation of the Americas by Europeans was abetted – and perhaps made possible – by epidemics of smallpox, measles and influenza brought unwittingly by the invaders, which annihilated many of the original inhabitants.

Read the text and answer question How to Make Friends While Traveling Solo Even in the best cases, traveling alone can get lonely. Here’s how to connect safely with the people you meet along the way. By Aric Jenkins April 16, 2019 Experiencing another culture on your own terms, at your own pace, with a budget of your own choosing can be an incredibly rewarding and insightful adventure. But while some may find such a journey liberating, others might worry about safety or a period of solitude in a strange, unfamiliar place. Humans, after all, are social animals. Prospective solo travelers should know that, despite its label, solo travel does not have to mean you’re alone all the time. There are local communities to safely interact with as well as fellow globe-trotters in a similar position. A 2016 report from travel research company Phocuswright found that a whopping 72 percent of hostel guests in the United States were traveling alone. Airbnb saw similar a trend in its data, with cities like Ho Chi Minh City, Cologne, and Johannesburg experiencing more than a 130 percent increase in individual bookings in 2016. With solo traveling growing in popularity, it’s clear there are options to socialize with other travelers — it’s just a matter of putting yourself in the right position to do so. Here are some tactics you can use to meet and befriend people abroad, from tried-and-true methods to innovative new apps and technology. Go on ‘free’ walking tours The word free is in quotations because, assuming your tour guide is at least half-decent, you should tip them at the end (many earn the majorityof their income on commission). But these walking tours can be worth every penny. Not only will the guide give you an informed and hopefully entertaining view of the locale, but you’ll have a chance to interact with other tourists and possibly come away with a new friend. (…) Use Airbnb to go on unique experiences hosted by locals Airbnb may be known more for its lodging arrangements, but it also wants to give you something to do at your destination. Airbnb Experiences connects travelers with local guides who lead guests on paid activities ranging from city tours to bar crawls and hobby and skill classes. Launched in late 2016, Experiences quickly became a popular feature. Connect with like-minded explorers on social travel apps Prefer to cut out the middleman and connect directly with other travelers? Try your hand at the crop of social networking apps specifically designed for travel. Travello, free on iOS and Android, allows you to discover other travelers nearby , match itineraries for planned trips and join groups based on similar interests. You can also create a feed by posting photos and updates. (…) Stay in hostels In a world of hospitable hotels and authentic Airbnbs, why do travelers elect to stay in hostels? Two reasons, really: Hostels are cheap and sociable. You’ll find college-esque dormitories with common lounge rooms and kitchens, and sometimes a bar or cafe. It’s an ideal environment to meet other travelers, and hostel staffs are well aware of this — some will lead city tours or pub crawls designed to foster interaction between hostel mates. Others might host game nights in the common room or arrange family dinners. (…) Adapted from the digital edition of The New York Times: www.nytimes.com

Opportunity Cost This phenomenon goes by the name of ‘opportunity cost,’ since by not investing in more equipment and a more rigid production flow, the company is forgoing the opportunity to earn increased profits. These costs are every bite as real as the payment of dollars out-of-pocket. This notion _______ opportunity cost can be reinforced _________ a famous saying ______ Benjamin Franklin, no slouch himself _________ operations management. To make the point, however, we must make a brief excursion into logic. One truth of logic is the validity of the so-called contrapositive, which says simply that if the statement “If A, then B” is true, then it is also true that “If not B, then not A.” That is, of every time A occurs B follows, then we can be sure that if B does not occur, then A did not occur as well. Enough logic then, and back to Ben Franklin. One of his Poor Richard sayings is that “A penny saved is a penny earned.” We have all recognized the truth of that since childhood, but I assert that by this saying Ben showed us he knows everything about opportunity cost. After all, what is the contrapositive of “A penny not earned is a penny not saved (i.e., a penny sent). All we are saying by this notion of opportunity cost is that “a penny not earned (an opportunity forgone) is a penny spent.” We shall often have occasion to consider opportunity costs, in analyzing and deciding various operations issues.

Text A French art expert believes a charcoal drawing kept in a collection for more than 150 years may be a preparatory sketch made by Leonardo da Vinci of the Mona Lisa.

The black-and-white drawing of a woman, nude from the waist up, known as the Monna Vanna, was previously attributed to Leonardo’s studio, suggesting it was done in his style by a pupil or follower, not by the master himself.

But after preliminary tests at the Louvre Museum, experts believe the sketch may well have been drawn by Leonardo.

Among the signs, according to curator Mathieu Deldicque, are the fact the drawing was made during the same period as the Mona Lisa, the paper is from the same region of Italy, and the technique is very similar to that of the Mona Lisa. “We know the drawing was made during the lifetime of Leonardo da Vinci, we know that the paper was made in Italy, between Venice and Florence, and the third discovery is the high quality of this drawing in the face of the Monna Vanna and in her arms,” Deldicque told reporters. “That’s very interesting because the arms are the same as the Mona Lisa‘s.” Leonardo, who lived from 1452 to 1519, was an engineer, scientist, inventor and sculptor, as well as one of the finest artists of the Italian Renaissance.

He painted the Mona Lisa, also known as La Gioconda and regarded as the world’s most valuable artwork, at the beginning of the 16th century.

It is believed to depict Lisa Gherardini, the wife of a successful merchant. EXCITING The charcoal portrait, in which the woman is holding a similar pose to the Mona Lisa but with her body more side-on and her head turned further over her left shoulder, has been held in a collection at the Conde Museum at the Palace of Chantilly, north of Paris, since 1862.

The Mona Lisa and Monna Vanna hold their hands in very similar ways, the right hand across the left and resting on the forearm, the fingers gently extended.

Deldicque said that while it was exciting to think the charcoal drawing was created by Leonardo, there were more tests to be done. “We have one more month of analysis and then a very slow process of history of art with a collection of analysts and advice by specialists,” he said.

It is possible that process will determine that the authorship is the same.

But it may also be inconclusive, he said, adding: “Maybe the mystery will remain.”
