Are the remains buried in a French castle really those of the master? Was the "Mona Lisa" a self-portrait in disguise ? A group of Italian scientists believe the key to solving those puzzles lies with the remains, and they say they are seeking permission to dig up the body to conduct carbon and DNA testing. If the skull is undamaged, the scientists can go to the heart of a question that has fascinated scholars and the public for centuries: the identity of the "Mona Lisa." Recreating a virtual and then physical reconstruction of Leonardo's face, they can compare it with the smiling face in the painting. "We don't know what we'll find if the tomb is opened. We could even just find grains and dust," says Giorgio Gruppioni, an anthropologist who is participating in the project. "But if the remains are well kept, they are a biological record of events in a person's life, and sometimes in their death." Silvano Vinceti, the leader of the group, said that _ in charge of the said burial site at Amboise Castle early next week. Leonardo moved to France at the invitation of King Francis I, who named him "first painter to the king." He spent the last three years of his life there, and died in 1519 at age 67. The artist's original burial place, the palace church of Saint Florentine, was destroyed during the French Revolution and remains that are believed to be his were eventually reburied in the Saint-Hubert Chapel near the castle. "The Amboise tomb is a symbolic tomb; it's a big question mark," said Alessandro Vezzosi, the director of a museum dedicated to Leonardo in his hometown of Vinci. Vezzosi said that investigating the tomb could help identify the artist's bones with certainty and solve other questions, such as the cause of his death. He said he asked to open the tomb in 2004 to study the remains, but the Amboise Castle turned him down. The group of 100 experts involved in the project, called the National Committee for Historical and... Question: The best title of this story might be " _ " - What Is the Purpose of an Investigation? - How Did Leonardo da Vinci Die in France? - Are the Remains Really Those of the Master? - Did Leonardo Paint Himself as 'Mona Lisa'?
**Answer**
Did Leonardo Paint Himself as 'Mona Lisa'?

Read the following article and select the best answer. Article: It's impolite to spit out the first bite of your dinner. But to a type of Australian snake, this rude behavior is a matter of life and death. The snake, called a floodplain death adder , eats two types of frogs that are hard to stomach. The frogs produce chemicals to defend them from predators . One of these species, the Dahl's frog, can kill a snake that tries to eat it. The other species, the marbled frog, is less dangerous but still tough to eat. When attacked, _ produces a glue like substance. Leaves and branches get caught up in this material, making a big sticky mess that gets in the way of anything trying to swallow it. A marbled frog can even get stuck on the head of an attacking snake. Both frogs have good defense methods. But the floodplain death adder knows how to get around each of them. Floodplain death adders quickly strike these frogs, using their poisonous teeth to inject poison. But then, instead of swallowing their dinner immediately, the snakes sit back and wait for their preys to become safe to eat. That's because both the Dahl's frog's protective toxin and the marbled frog's glue break down over time. After a while, the frog toxin is no longer poisonous and the glue is no longer sticky. The two substances break down at different rates, and floodplain death adders seem to know the difference, And adder waits for a different length of time depending on the species of frog it just struck. The stickiness of the marbled frog glue decreased by as much as two-thirds after just 10 minutes. And that's just about how long an adder waits before eating a marbled frog. On the other hand, the snakes wait for about 40 minutes before eating a Dahl's frog. That's enough time for the frog's toxin to break down into harmless substances. But even a quick strike gives a taste of the Dahl frog's toxin. After striking such a frog, a floodplain death adder thrashes around and lies on its back with its mouth open, It's like the snake has just had a... Question: The glue produced by the marbled frog is used for_. - sticking the snake's head - making a safe place to live in - preventing anything from tying to attack it - killing an attacking snake
**Answer**
preventing anything from tying to attack it
