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: What's the best title of the passage?

Read the article and select the best answer. Article: Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness. The first kind of loneliness is temporary. This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situational loneliness, is a natural result of a particular situation -- for example, family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year. The third kind of loneliness is the most severe. Unlike the second type, habitual loneliness usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition. Psychologists agree that one important factor in loneliness is a person's social contacts, e.g. friends, family members, co-workers, etc. We depend on various people for different reasons. For instance, our families give us emotional support, our parents and teachers give us guidance, and our friends share similar interests and activities. However, psychologists have found that, though lonely people may have many social contacts, they sometimes feel they should have more. They question their popularity. Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between habitual loneliness and serious illness such as heart disease. While temporary and situational loneliness can be a normal, healthy part of life, habitual loneliness can be a sad and sometimes dangerous condition. Question: What is the best title for the passage?
